September 18, 2017

Huntsville, AL – GeoCue Group Inc. (GeoCue) is excited to announce a new GNSS positioning system that will allow users of DJI Phantom 4 Pros and Inspire 2 drones (as well as most drones using higher end cameras) to achieve survey-level accuracy with a minimum of ground control. Loki, our new direct geopositioning system for small unmanned aerial systems solves the two fundamental problems associated with this technology:

  • Positioning Accuracy – Loki uses the new AsteRx-m2 multi-frequency, multi-constellation GNSS engine from Septentrio. With 448 hardware channels, finding and locking satellites is not a problem!
  • Camera Events – GeoCue has invented a patent-pending method of detecting camera events from Phantoms/Inspires and synchronizing those events to GNSS positioning. No modifications to the drone are necessary; the adapter cable is “plug and play.”

Loki is a self-contained kit that provides all of the hardware and software needed to equip your drone with a Post-Processed Kinematic (PPK) multifrequency, multi-constellation, differential, carrier-phase Global Satellite Navigation System (GNSS). Using a local base station (not included), Loki provides centimeter level positioning with minimal, and in some cases, no ground control points (though GCPs are always recommended for quality assurance).

“GeoCue has been a long time Septentrio OEM development partner,” said Neil Vancans, Vice President of Septentrio Americas. “They have offered our previous generation sUAS board on their high-end AV-900, achieving remarkable results in both accuracy and reliability. By solving the problem of connecting the virtual camera trigger on DJI drones to our AsteRx-m2 GNSS engine, they can achieve professional mapping accuracies with consumer-grade UAVs.”

DroneDeploy of San Francisco has become the leader in cloud-based processing for DJI (as well as other) drones. They have enabled users of Phantom and Inspire drones to easily upload drone images, work on-line with analytics, and download point clouds and orthophotos to desktops for advanced processing. Without Loki, achieving acceptable network accuracy requires the time-consuming placement of ground control targets throughout the mapping site. GeoCue and DroneDeploy have been working together to ensure a smooth Loki-DroneDeploy workflow from field to finish.

“The GeoCue Loki system is an exciting product for anyone using drones to make maps with high accuracy," says Mike Winn, CEO and co-founder of DroneDeploy. “The Loki’s combination of high-end GNSS positioning and DJI camera synchronization enables survey-grade accuracy with the simplest workflow that we’ve seen— making the Loki a great fit for the DroneDeploy platform."

“I am very excited to be working with industry leaders such as DroneDeploy on our Loki project,” says Lewis Graham, President and CTO of GeoCue Group. “Loki provides high accuracy positional data to downstream processing solutions. More significantly, it does this for DJI Phantom 4 Pro and Inspire 2 drones. Combining DJI, Loki and cloud processing solutions such as DroneDeploy provides a very streamlined and cost effective solution for high accuracy site surveys.”

The Loki kit includes:

  • Loki PPK Controller using the Septentrio AsteRx-m2 GNSS engine (GPS L1, L2, L5 and GLONASS L1, L2, L3, 448 hardware channels).
  • Maxtena M1227HCT-A2-SMA high performance, active, multiband GNSS antenna
  • Antenna ground plane with mounting kit
  • Antenna to controller cable
  • USB cable for data transfer and Loki controller charging
  • Personality cable (user selects either DJI or DSLR)
  • AirGon ASP software suite
  • Mounting kits for DJI Inspire 2 and Phantom 4 Pro
  • 1 year of maintenance and technical support

Loki requires a local multifrequency base station (not included but available from GeoCue). Loki is shipping to early adopter customers in August 2017. It will be available for the general market in September 2017. It will release with direct support for DroneDeploy and AirGon’s Bring Your Own Drone (BYOD) Mapping Kit. Loki’s introductory price will be USD $4,995. GeoCue is currently accepting preorders.

Loki will be on display September 6-8 at the InterDrone 2017 conference in Las Vegas and at Commercial UAV Expo, also in Las Vegas, October 24-26. A workshop dedicated to high accuracy mapping with DJI drones using Loki is being held in conjunction with the Commercial UAV Expo. Register at www.expouav.com.

Lewis Graham, GeoCue Group - Some years ago, we formed AirGon, our drone mapping subsidiary. Of course, being in the LIDAR and imagery business, we have always had a laser focus (pun intended here!) on high metric accuracy. For drone mapping with cameras, this means an on-board direct geopositioning system. For LIDAR mapping, orientation must also be known so the solution is onboard direct positioning and orientation system (POS). I thought it might be interesting to explore some of the options for direct geopositioning; we'll leave POS for a future article.

At the end of 2016, we started investigating the possibility of doing serious mapping with very low end drone platforms such as the DJI Phantom 4 Pro and the Inspire 2 (with Zenmuse 4Xs cameras). We think these are the minimum drones (as compared to say the Phantom 3) because of some significant improvements to the cameras. The first is that the sensor size has been increased to 1" This is really . the minimum you should consider in a drone mapping camera. The second big improvement is the inclusion of a leaf global shutter. The rolling shutters of cameras primarily designed for video acquisition wreak havoc on photogrammetry solutions. With shutter speeds at or slower than 1/2000 s these new cameras employ a leaf shutter. We have calibrated these two cameras dozens of times and find fairly good stability.

Lewis Graham, GeoCue Group - Some of you reading LIDAR Magazine this month are recipients of airborne LIDAR data, not producers. Rather than being in the thick of the sausage making acquisition and processing chain, you are receiving the data as the end use organization. What should you do?

We are the creators of LP360, one of the most widely used tools for performing comprehensive LIDAR data testing. We have been recently adding some new tools for the USDA and USGS to assist with some of the file content inspections that are applied to contractor-produced data (a cool new tool called "LAS File Analyst"). This work has me thinking about LIDAR quality and what recipients should be doing as standard practice.

Lewis Graham, GeoCue Group - We provide (mostly through our AirGon subsidiary) a lot of technology and services into the drone mapping market. Our focus is primarily on site types where drone mapping is a more economical alternative than manned airborne or traditional surveying. This range of application includes quarries (open pit mines), industrial sites and bare earth construction projects. At the moment, we use only dense image matching technology to create 3D models of these sites. I have discussed the strengths and weaknesses of dense image matching (DIM) in several Random Points columns but the net is that DIM is inexpensive (the plus) but cannot penetrate vegetation (the minus).

We sometimes are asked to do mapping of or provide technology for sites that have vegetation cover such as that of Figure 1. The magenta points are topo shots collected with an RTK rover. Note in the profile view that these shots appear far below (over 6 feet) the surface derived from the DIM model. In fact, due to miscorrelation by the DIM creation software, the points are distorted in the vertical by more than twice the height of the vegetation. This should dispel any notion of simply subtracting an average vegetation height from the DIM to arrive at an approximate model; you simply cannot use DIM modeling in these types of situations. We need a LIDAR!

Lewis Graham, GeoCue Group - As we all know, a "Moore's Law" of the LIDAR hardware industry seems to be a doubling of data resolution every few years. In fact, resolutions have become so high that we may have to begin to modify how we treat LIDAR data (as well as point clouds derived from dense image matching).

Recall (discussed in past Random Points) that resolution is the granularity with which we can measure something. With LIDAR point cloud data, resolution is the density in the planar (X, Y) dimension and fineness with which we can read elevations in the Z dimension. For example, data with a nominal point spacing (NPS) of 20 cm has twice the planimetric resolution of data with an NPS of 40 cm (and four times as many points).

Lewis Graham, GeoCue Group - AI recently attended a transportation conference and sat in on a talk given by some GIS graduate students. The subject of the talk was generating predictive driving data based on real time inputs from GNSS-equipped cargo trucks. The idea was to improve transport efficiency over the monitored segment (about 40 km) by using analysis of driving habits and providing corrective feedback.

The talk was rather interesting, with a lot of discussion of the real time data collected by GNSS on the trucks, the transfer of data and other factors. The base map being used was Google Maps because that was the "free" data that was available and, as a bonus, it had elevation data. The elevation data were useful because part of the analysis was the efficiency with which hills were being traversed. There was an analysis section that discussed the track deviations from the road centerlines and the probable causes. Methods were suggested for improvements in future studies. Mind you, this was a funded project with a lot of hardware purchased and installed. As I say, it was rather interesting. The only criticism I have is that the design and conclusions were mostly wrong!

Part 107 has gotten the mapping industry as a whole to take a closer look at what UAVs can do in terms of complementing or completely replacing some current mapping approaches. At the ASPRS Hot Topics session, which took place at the International LiDAR Mapping Forum, this topic was explored in great detail by numerous organizations that have created the products that are enabling those new approaches.

Qassim Abdullah from Woolpert and Lewis Graham from the GeoCue Group led the session, which allowed a number of UAV manufacturers to provide their perspective around where drone technology is at right now, and how these tools can be used on projects of all types and sizes. After that, a different set of manufacturers provided some insight around mobile mapping technologies to show the strengths and capabilities of the technology. Those strengths and capabilities were both directly and indirectly compared to UAV capabilities.

Lewis Graham, GeoCue Group - I used part of my Thanksgiving holiday to catch up on some industry reading. What I find is rather disturbing. The offending information is primarily coming from overview articles in online sources regarding small unmanned aerial systems (sUAS) and their data collection accuracy. While much of the information is useful, the statements regarding achievable accuracies and the techniques that can be employed are, for the most part, patently false. I find this to be a very disturbing trend because while practitioners of the art (e.g. professional land surveyors and others schooled in geomatics) will recognize the errors, executives making decisions about deploying technologies could be led to take entirely wrong decisions.

All of this made me think about geopositioning and how we make statements about project accuracies. For example, I often read articles that state project accuracies in terms of residuals measured from signalized ground control points (see Figure 1 for an example of a control/check target).

Lewis Graham, GeoCue Group - We have an enterprise systems division of our company that primarily develops technology for organizing and processing point cloud and raster data. Within this body of work and projects we have commercial product development such as our LIDAR Server technology as well as custom development such as a very large system hosted in Amazon Web Services that will be used, among other data, for managing a near real time space-based hyperspectral imager.

One of the primary choices one faces when designing such systems is the format that will be used for storage, presentation and delivery (which are not necessarily all the same) of various types of data. We are engaged in a large LIDAR data management and dissemination project for one of our key US government customers. We recently became involved in a discussion of raster versus point cloud for LIDAR data storage and delivery. I thought this debate had died long ago but it still occasionally comes up (especially from companies who support only one format!). I think it continues to surface because point clouds are a real problem to work with. Rasters are so nice and simple—can't we just make everything a raster?

Jeremiah Karpowicz - The AirGon booth at the Commercial UAV Expo literally had a sign that said, “Ask About Our BYOD Mapping Kit”, so I did just that with Lewis Graham, President/CTO of GeoCue Group. I had previously connected with Lewis to get his thoughts around whether or not drones are destined to become another survey tool, and if every survey truck has a drone on it in within the next few years, there’s a clear answer to that question.

During the interview, I asked Lewis a number of questions that focused on how professional surveyors can and are using the Kit. He discussed why it’s a good bridge for people who want to enter this market, what sort of feedback they’ve gotten about the kit, what the process to get started looks like and more.

Watch Interview

Jeremiah Karpowicz - We’ve all seen and heard the predictions around how many billions of dollars the world drone market possesses. Whether it’s the $82.1 billion between 2015 and 2025 that the AUVSI predicted in their report from a few years ago or the more recent $127 billion predicted by PwC, it’s safe to say there’s a lot of excitement about UAV technology.

Leaving aside the legitimate concern that such predictions are far too ambitious, few would argue about the tremendous potential drones possess in terms of both costs and the approach that can be taken on a given project. Now that we have Part 107, the barrier to entry that had kept many people from fully exploring the technology has been eliminated. Professionals of all types and sizes are trying to figure out how they can turn such predictions around the economic impact of the technology into reality. However, doing so has proven to be a challenge, especially for surveying and mapping professionals.

The reasons behind such challenges vary from person to person and from organization to organization, but many are related to the logistics associated with assembling a viable commercial drone platform. What sort of workflow should be utilized? How should deliverables be handled? Where is all of this info going to be stored? These were just some of the challenges that led AirGon to create the Bring Your Own Drone (BYOD) Mapping Kit.

Watch Interview

Lewis Graham, GeoCue Group - As I have mentioned in a number of past columns, we are addressing the small UAS mapping industry via our subsidiary company, AirGon LLC. While our primary business is developing and/or integrating technology to provide turnkey mapping systems, we also provide a small amount of mapping services. I have two goals for this services business; help customers transition from a services model to an owner-operator model and inform the development of our point cloud analytic software, TopolystTM.

When we first engage with a customer, we are usually put to a test. This test is "how do your results compare to those I have been obtaining through my existing data acquisition methods?" This is where a confusion in terminology exists between what is being collected via conventional photogrammetric stereo and new techniques. The use of inconsistent terminology in the press and various white papers only adds to the confusion.

Lewis Graham, GeoCue Group - Okay, okay, I know you are tired by now of reading about the new regulations for commercial small unmanned aerial systems (sUAS) that will take effect in the United State in late August. However, there is a real gem in these rules that it seems no one is discussing. In fact, I think it may be the most important rule of the entire Part 107.

First of all, a very, very big caveat! I am neither a lawyer nor a pilot so take everything in this article with a big grain of salt. I am not responsible for misinterpreting Part 107 and I won't come visit you in jail! After all, if you have read it cover to cover (as I have) you will realize it is not the easiest document to summarize!

Lewis Graham, GeoCue Group - Several months ago, I introduced Topolyst, our small Unmanned Aerial Systems (sUAS) processing software. One of the great features in Topolyst are tools to automatically create the footprint ("toe") of a stockpile and to optionally classify overhead points so that they are excluded from subsequent processing (such as cross sections or volumetric computations). An example of a stockpile with an overhead conveyor, prior to toe finding and classification, is shown in Figure 1. As seen in the 3D view in the upper right, the conveyor simply blends in with the stockpile, giving a grossly inaccurate volume for this pile.

Lewis Graham, GeoCue Group - One of the relatively new advances in commercial LIDAR technology is multibeam systems with different wavelengths for each beam (unlike multibeam with the same wavelength used simply to increase effective pulse rate). These so-called "multispectral" LIDARs are becoming quite common in the bathymetric arena where infrared is needed to detect the water surface and green is needed for water column penetration.

In 2014, Optech introduced a new system ("Titan") specifically aimed at extending the multispectral notion beyond simple infrared and green. Are we at the onset of multispectral active sensors? Let's casually explore what is meant by multispectral when it comes to LIDARs.

Jeremiah Karpowicz - It’s no stretch to say that we’ve come a long way in a short while when it comes to how professionals are using drones and even how UAV technology is perceived. Over the past few years there’s been an incredible evolution in terms of what users expect out of these tools, and while technological advances have driven much of that, some of these changes are really about a much deeper level of acceptance and understanding.

Lewis Graham, GeoCue Group - All of us are now, of course, aware of the "cloud." In fact, a lot of folks are in a semi-panic because they are not "on the cloud", sufficiently "using the cloud" and so forth. In this month's column, I want to explore cloud deployment a bit and see where it makes sense for data production and exploitation.

Lewis Graham, GeoCue Group - I was recently engaged in a discussion regarding topics to be considered for a technical seminar. Naturally the subject of Big Data (it is only appropriate that Big Data would use big letters, right?) came up. After all, our industry defines Big Data with the collection and processing of remote sensed information of every ilk. As the discussion progressed, my mind drifted off into thinking about what these things mean, from a contextual point of view.

Lewis Graham, GeoCue Group - I was recently engaged in a very interesting conversation with a company who is performing a number of survey related operations for mine site management. This conversation led me to think, once again, about the overall issues of accuracy.

Lewis Graham, GeoCue Group - I was recently giving a talk on mine site mapping using small Unmanned Aerial Systems (sUAS) where I was sort of verbally attacked about licensure. It is bad enough that the FAA requires a pilot license to fly a model airplane and now this person in the audience was indignant that I was not a big advocate of also requiring a professional land surveyor (PLS) license.

Lewis Graham, GeoCue Group - We have been developing tools for surface mine site (quarry, stock pile yards) mapping using small unmanned aerial systems (sUAS) for the past several years. Mine site volumetrics are ideal candidates for sUAS technology for a variety of reasons. First of all, the stockpile areas tend to be compact, often less than 50 acres. This makes these sites amenable to flying with a rotary wing sUAS. Secondly, they tend to be free of vegetation. Overhead interference such as vegetation is a real issue for dense image matching algorithms. Evan so, these sites are not without their challenges.

Lewis Graham, GeoCue Group - I have been the chair of the LAS Working Group (LWG) of the American Society for Photogrammetry and Remote Sensing (ASPRS) since the inception of LAS in 1999. This ubiquitous format has slowly evolved over the years (it is now in its fifth incarnation, LAS 1.4) to support new features added to commercial LIDAR collection systems. It has always been focused on kinematic collectors (the sensor is in motion during scanning) rather than static systems such as tripod scanners. In addition to LIDAR, LAS has become the de facto standard for encoding point cloud data from dense image matching such as processing of unmanned aerial systems projects.

Lewis Graham, GeoCue Group - We have been adding a new "Live View" control to our point cloud exploitation product, LP360. This control allows much easier manipulation of the display of point cloud data based on attributes such as classification and returns. While testing the Returns portion of the control, I was reminded of the very high value of this attribute for exploiting LIDAR data.

Lewis Graham, GeoCue Group - Using a drone and low-cost camera, producers can make accurate
 volumetric computations.

Volumetric data is a critical piece of information for aggregate operations. Yet economical, accurate and timely collection of such data remains elusive for most operators.

Several major developments in technology during the past eight years have enabled a new approach to collecting volumetric data for surface mining and stockpiling. Bearing a digital camera, a small unmanned aerial system (sUAS, or drone) can rapidly collect imagery that can be subsequently processed into a very accurate 3D model of the imaged area.

Lewis Graham, GeoCue Group - The United States Geological Survey (USGS) 3D Elevation Program (3DEP) is now in full swing. 3DEP is an expense sharing program with the goal of collecting high quality LIDAR data for the conterminous United States, Hawaii, and the U.S. territories with Alaska being covered by synthetic aperture radar (SAR) elevation data. The goal is to acquire these data over an eight year period and, one would assume, to repeat ad infinitum.

Lewis Graham, GeoCue Group - In the last Random Points, I rambled on about something I am marginally qualified to address--optimal design.

Lewis Graham, GeoCue Group - Drones are being used for a wide variety of commercial tasks, ranging from real estate photography to metric mapping. In the United States, the vast majority of these tasks are conducted outside the scope of the commercial rules for operation as specified by the Federal Aviation Administration (FAA). Folks either are unaware that rules even exist or they are taking a calculated risk of ignoring them. Those who are trying to obey the rules are spending thousands of dollars on attorney fees applying for FAA exemptions ("Section 333 exemptions"). Something has to give!

Lewis Graham, GeoCue Group - As I write this article (early January 2015) the Federal Aviation Administration (FAA) has yet to release rules for the commercial use of small Unmanned Aerial Systems (sUAS) in the USA airspace.

Welcome to the November edition of GeoCue News!
Lewis Graham, President and CTO, GeoCue Group

I hope everyone is enjoying a nice fall (or spring for those of you on the top side of the planet!).
We have been extremely busy during this last quarter of 2017. Our “Mapping with DJI Drones” seminar held in conjunction with the Commercial UAV Expo sold out months before it was held. We provided detailed workflow information from our Loki Direct Geopositioning System for DJI (and other) drones through the BYOD Mapping Kit. Those who attended provided us with a lot of positive feedback. We’ll repeat this as webinars and local events during 2017. Just last week DroneDeploy (www.dronedeploy.com) announced their selection of our Loki system for direct geopositioning in DroneDeploy cloud processing workflows. We have been working with them for the past several months to ensure a smooth user experience.
We added Puerto Rico to our hurricane LIDAR data support site, GetLIDAR.com. You can download LIDAR data of Puerto Rico, Harris County TX (Houston) or Florida to your Amazon buckets (we tell you how to set these up) at no charge. We are funding this as our contribution to hurricane relief efforts.
We are wrapping up our new licensing for LP360. This will provide customers who have floating licenses a new feature that will allow these licenses to be checked out to a laptop for roaming. This is our most often requested licensing feature. The new licensing is provided via a cloud-hosted server so you will no longer need to maintain a local license server. We’ll write a detailed article for this when we release LP360 2017.2.

Point Cloud Exploitation
Automatic Ground Classification of Dense Point Clouds in LP360
Lewis Graham
The density of point clouds (usually expressed as points per square meter) is increasing on what seems to be a monthly basis. This is particularly true of point clouds derived from Dense Image Matching (DIM), the clouds produced from software such as PhotoScan, Pix4D, DroneDeploy and so forth.
You can quickly check the density of a point cloud in LP360 using the Point Cloud Task (PCT), Point Cloud Statistics Extractor. Figure 1 shows this PCT set up to collect Point Count and Point Density.

TerraScan provides users with many different methods of visualizing their point cloud data. One of the most powerful is through the Display Mode dialog and the now nineteen modes from which to choose. Recently we have seen new modes made available including: The mixing of various modes together with Intensity, as well as point groups display options. This is a brief review of the older modes as well as these newer ones, including descriptions, uses, and example.

LIDAR Production Solutions
TerraScan: Range Classification for Terrestrial Scanner Data
GeoCue Group Support
Recently, a customer had a question about using the ‘Classify by Range’ (TerraScan -> Classify -> Routines -> Classify by Range) classification routine with terrestrial scanner (tripod-mounted static scanner) data. This tool classifies points based upon each point’s respective range from the scanner’s position at the moment of collection. This tool was designed to improve mobile LIDAR point cloud processing by eliminating the less dense and lower accuracy points that exist furthest from the sensor. This capability is also needed when processing data derived from a stationary scanner. This tool requires trajectory information. Unfortunately, static scanners do not have this kind of information. A very short trajectory could be constructed for the scanner position, but this also requires that the data is time-stamped as well, which may not be the case with this kind of scanner. There are alternatives to this option that can accomplish the same goal with minimal fuss.

Welcome to the October edition of GeoCue Group News!
Lewis Graham, President and CTO, GeoCue Group

Welcome to the October edition of GeoCue Group News! I hope you are enjoying nice fall weather if you’re on the north half of the planet and an enjoyable spring if you are on the other side.

We have been extremely busy this last quarter at GeoCue. We have been working with Teledyne Technologies on a new platform for managing and distributing data from a sensor array that Teledyne is mounting on the International Space Station (ISS). We are commercializing the Amazon Web Services (AWS) portion of this system to enable management and distribution of very large imagery and LIDAR data sets. The commercial spinoff, known as Earth Sensor Portal (ESP), got an unexpected public test. During a GeoCue discussion, we were trying to think of a meaningful way our company could contribute to the hurricane relief efforts for Texas, Florida and Puerto Rico. We thought that pre-event imagery and LIDAR could be extremely useful and set off to have a look. Turns out that while these data have been collected for all three areas, it is not so easy to get your hands on it. We decided to stand up a free data portal for the affected areas using our in-progress version of ESP. The USGS was extremely interested in cooperating with us because while they already had a lot of data in AWS S3 storage, there was not a public portal for download. In a similar vein, the Texas Natural Resources Information System (TNRIS) has lots of LIDAR data for Harris county but it had to be delivered on disk drives. We quickly stood up GetLIDAR.com to serve as a free clearing house for these data. This turned out to be extremely successful, validating the concept of cloud archiving, search and delivery for these type data. See our Director of Enterprise Solutions’ (David Glenn) article on GetLIDAR in this issue.

We have also released to manufacturing and delivered to customers our new direct geopositioning system (DGPS) for DJI (and other) drones. Dubbed Loki, the system is based on the proven Septentrio-based DGPS we developed for our AV-900 mapping drone. The really cool thing about Loki is that it enables PPK positioning on a DJI Inspire 2 drone (Phantom 4 Pro and m200 should be available by year end). We recently conducted a nine-flight sortie over a quarry with over 75m of vertical terrain relief using Loki on a DJI Inspire 2 with DJI X4s camera. We used no ground control (of course we had test points for accuracy assessment) and combined all nine flights into a single PhotoScan Pro project. Our vertical error was a stunningly good 0.136 foot (4.1 cm). This level of accuracy will support ½ ft contours. Now if you are a surveyor, you may not be impressed. However, sit back and think about the equipment; a $3,600 drone/camera combination with a $6,000 DGPS and no ground control at all, achieving an accuracy sufficient for differential volumetrics. This is really a game changer!! We’ll be updating you on the Loki system in most issues of the newsletter. In the meantime, have a look in this issue at the case study of the use of our drone data processing technology.

Have a great quarter! If you are a GeoCue customer for any of our technology (thank you very much!), see in next month’s letter. Otherwise, please be on the lookout for the January issue.

GeoCue Launches GetLIDAR.com to Support Hurricane Recovery
David Glenn
When natural disasters occur, one of the more pressing needs of disaster recovery teams is access to trust-worthy, pre-event data. Typical needs are for recent aerial images and elevation data, preferably orthoimages and LIDAR data. It can be difficult to find sources for this data, sources that can be easily accessed from any location, trust worthy with respect to data integrity and accuracy, and which provide a simple, straightforward interface to extract and deliver data to local computers for processing. GetLidar.com provides such an access point for data relevant to the areas in Florida, Texas and Puerto Rico heavily damaged by hurricanes Harvey, Irma and Maria.

Internalizing LIDAR Data Processing
Martin Flood
At GeoCue Group we are involved with customers across the mapping industry, from hardware designers through data collators and data analysts to end users, so we often get asked the question, “how much data processing should I do myself?” It is a great question. How much of any given business process you decide to internalize must be a key part of your overall growth strategy. Unfortunately, we often see companies making one of two classic mistakes when approaching this question about bringing LIDAR data processing in-house. The first mistake is to decide to do something just because you can, and being smart engineers and scientists, we all believe we can do LIDAR data processing! In fact, from a practical point-of-view, this is probably very true. Most engineering, survey and mapping firms have the technical capability and skills already on staff, or can acquire them by hiring experienced people, to take on LIDAR data processing. LIDAR data is no more complex than many of the other geospatial data types companies routinely process in-house. It has some unique aspects to it, but the workflows, tools and techniques are very teachable and can be learned, although there is no substitute for experience. But, just because you can do a thing does not mean you should do that thing. For LIDAR data processing, a compelling business case must exist to justify internalizing the process.

Fixing Time Consuming Inventory Collection
An AirGon Case Study with Philips' Soil
We conduct a core product inventory every quarter for our bark and pumice stockpiles to keep our bookkeeping updated. Our inventory collection methods consisted of simply guessing the volume of each pile (highly inaccurate) or having our loader operator move 5 yards of product at a time (extremely time consuming, difficult, and dangerous). In the end, our volume collecting methods were costing the company a lot of time and money.
After contacting AirGon for help, we acquired the Bring Your Own Drone (BYOD) Mapping Kit. With the BYOD Mapping Kit, we are able to complete our inventory collection from start to finish in one hour.

Welcome to the September edition of GeoCue Group News!
Lewis Graham, President and CTO, GeoCue Group

We’ve just completed our 2017 LP360 User Group and Training meeting here in Huntsville. There will be more on this event in next month’s newsletter but we were very pleased with the reaction to all of the new feature edit tools in LP360 (standalone). The feedback was that these new tools will enable very large savings in the time required to digitize features and breaklines.
I am pleased to report that we have begun shipping our new Loki direct geopositioning system. Initial units have been shipped to customers for the Inspire 2 and DSLR versions of the system. We also have released the completely new ASP Suite for postprocessing Loki and DJI data. We have done extensive testing of the system and are still amazed at the accuracy that can be achieved with a DJI Inspire 2 carrying a Zenmuse X4s camera. We’ll have a white paper out on this in the next month. If you are interested in very high accuracy mapping with DJI drones, be sure to sign up for our colloquium being held in conjunction with the Commercial UAV Expo in October.
Our first preview of the Amazon hosted Earth Sensor Portal (ESP) will roll out next week in support of hurricane relief efforts. We will be posting all of the USGS 3DEP LIDAR data for the state of Florida as well as pre-event LIDAR and imagery data for Harris County (Houston), Texas. These data will be available for transfer to your own Amazon Web Services (AWS) S3 bucket at no charge. Look for the announcement of a GoToMeeting training session on obtaining these data from ESP in the next week.

UAS Metric Mapping
An Introduction to ASPSuite
We are releasing a significant update to the AirGon Sensor Package Software Suite (ASPSuite or just ASP) with the release of our new direct geopositioning system (DGPS), Loki. ASPSuite is the intermediate step between landing the drone and feeding data to the Structure from Motion (SfM) software (PhotoScan, Pix4D, DroneDeploy and etc.).
ASPSuite is available in two licensing levels, Standard and Advanced. The Standard level is useful when you are not using a Loki DGPS on your drone. It provides tools to help you manage flights and, more importantly, to fix some errors that DJI makes in assigning altitudes to images; if the altitudes of your flight are not approximately correct, your automatic camera calibration software will resolve an incorrect focal length. It also will geotag images as a final processing step. ASPSuite Standard edition is included with the Bring Your Own Drone (BYOD) Mapping Kit. ASPSuite Advanced Edition adds drivers for RTKLIB, the software we use for obtaining the DGPS solution as well as tools for geotagging images and correcting event mismatches. ASPSuite Advanced edition is included with each Loki package. Additional licenses of both levels can be separately purchased.

Point Cloud Exploitation
LDExport - An LP360 Command Line Executable
LP360 has several very useful command line executable utilities that can be used to simplify different tasks or improve the efficiency of large batch processes when working with substantial amounts of data or repeating processes. LDExport was added to this utility catalog with 2017.1. It simplifies the export of LAS points and surfaces, for example when generating output products. LDExport can be found along with the other command line utilities at C:\\Program Files\Common Files\QCoherent (or Program Files (x86) for 32-bit installs.

Automating Volumetric Reporting in TerraModeler
When producing volume reports, TerraModeler, as with all Terrasolid software follows a convention of producing ASCII reports. These reports can then be easily integrated into formats desired to produce respectable deliverable reports. In the case of volume reporting, TerraModeler supports a nice and easy reporting method using an external application that replaces multiple values in a document. This find and replace tool eliminates the need to transcribe or copy and paste measurement values into final reports, which can not only save time, but can also eliminate transcription errors.

Welcome to the August edition of GeoCue Group News!
Lewis Graham, President and CTO, GeoCue Group

Here at GeoCue, we have had a tremendously busy summer thus far. We just posted the Experimental (EXP) release of version 2017.2 of LP360. This version has the new LAS File Analyst which is a terrific new set of capabilities if you need to test or fix LAS point cloud files.
We are also in the midst of releasing Loki, our new direct geopositioning system for DJI drones (or any drone carrying a DSLR camera). This is a hardware and software product so there are a lot of moving parts. It is a game changer, I think. We are seeing some pretty phenomenal accuracies from a DJI Inspire 2 with X4S camera. We should be shipping the initial Loki units next month (September).
We will be releasing a major update to the ASPSuite software within the next month. This update adds Loki support as well as simplifying the interface for both direct geopositioning and DJI position repair, for those using our BYOD Mapping Kit without Loki.
We have two major training events coming up that you should seriously consider attending. The first is our annual LP360 training in Huntsville, September 11 through 14. The second is a colloquium on high accuracy mapping to be held in conjunction with the Commercial UAV Expo in Las Vegas on October 24th. If you are interested in getting into the drone mapping business at a reasonable budget, come to this event!

Downloading Image Layers in Reckon
Viewing uploaded images on the Reckon website is a great way view orthomosaics and hillshades. If a user needs to download an image to view it offline or in a different program (LP360), this can be accomplished by downloading the image from the web-client. Downloading image layers in Reckon is an easy and secure process that allows the administrator to easily disseminate orthomosaic and hillshade images to designated users.

Classify Surface Points Routine
Photogrammetric point clouds are notoriously noisy, very dense, and generally lack points located underneath vegetation. Echo information is non-existent and surface roughness are not as useful for ground classification with these point clouds. Point clouds from low quality LIDAR sensors exhibit some similar characteristics. Hence, a different approach is needed.

Smoothen Points - XYZ Option
Smoothen points is a command that smoothes the attributes of points relative to adjacent points. Until recently, the modifiable point attributes were elevation, intensity, or color. The elevation option could be used to iteratively adjust elevation values of points using plane-of-best-fit equations to result in a smoother surface. The intensity option could be used to average the intensity values of points with their neighboring points to help make better looking intensity images. In a similar manner, the color option could be used to average the color values of points with their neighboring points to help make better looking 3D colorized point clouds. Starting with TerraScan version 017.001, a new smoothen XYZ option was added to the Smoothen points command. This XYZ option modifies points so that they better match a 3D surface. This option can be used as an optional step when processing noisy data such as a photogrammetric point cloud or data from low quality laser scanners.

What We Do
Since this is our first general distribution newsletter in a few years (see the introduction), I thought it would be a good idea to review a bit of the history of GeoCue Group Inc. and what we do.
We formed the company under the name NIIRS10 (that’s another story!) in July of 2003. Thus this is our 14th birthday! Prior to forming this company, I was the CEO of Z/I Imaging, a global photogrammetry hardware and software company. Z/I was acquired by Intergraph in 2002 (the point at which I left the company). Intergraph was, of course, subsequently acquired by Hexagon, the new home of Z/I Imaging. Our core group of developers joined me from Z/I and thus have a long and rich history in developing advanced photogrammetric and LIDAR hardware and tools.

Mapping the Battle of Gettysburg - Little Round Top Revealed
GeoCue Group recently partnered with the National Park Service (NPS) in a pilot project to assess culturally significant areas within Gettysburg National Military Park using small unmanned aerial systems (sUAS). The area of interest (AOI) for this project was the western face of Little Round Top (Figure 1). Little Round Top was the location of a defensive stand by the Union army during the Civil War Battle of Gettysburg. On July 2, 1863, Confederate forces attempted to capture Little Round Top—the left flank of the Union line (Pfanz 1987). This fight included the famous bayonet charge led by the Union Army’s 20th of Maine Volunteer Infantry Regiment, under the command of lieutenant colonel Joshua Chamberlain, who captured and repelled the advancing Confederate Army’s 15th of Alabama (Desjardin 1995). The Confederate attack was ultimately unsuccessful. The Union Army would use the hill to counterattack and as an artillery battery position later in the Battle (Hall 2003).

Terrasolid: The Workhorse is Still a Valuable Tool in LIDAR Production Shops
As the North American reseller for Terrasolid’s software suite, we get to work with the majority of the LIDAR production shops in the US and Canada. The Terrasolid suite – TerraScan, TerraModeler, TerraMatch and TerraPhoto – continues to be common-place on the production floor regardless of the type: airborne, mobile or terrestrial. And increasingly we see UAV operators deploying Terrasolid to assist with their own point cloud workflows, whether LIDAR or imagery based. The focus of the industry is often on the what is new and different and exciting, on the “latest and greatest” so this week we thought we’d step back from the hype and hoopla and check-in with a long-time user of Terrasolid to see how this old workhorse of the LIDAR production shop is doing these days.

LP360 in the Classroom: Pennsylvania State University
My final project for my LIDAR class was to extract building heights using LIDAR collected after Superstorm Sandy for the City of Newark.  Using LP360, I created a Point Cloud Task workflow to classify points within a set of building footprints. My final product included a DEM of the ground points and a DSM of the building heights.

Welcome to the June 2017 edition of GeoCue Group News!
Back in the old days, we sent this newsletter out to our entire contact database (a lot of folks who are in businesses that either currently use or could potentially use our products). Being a bunch of engineers rather than marketing folks, the newsletter has always been full of very detailed technical information. I started to realize that this was probably only of interest to our current customers so about two years ago we narrowed our list to this group. Recently, however, we have been getting a lot of requests for articles that we publish that contain information of broad interest such as picking a drone, how to place control targets, managing LIDAR data and so forth. As a result, we are restructuring our newsletter so that every third issue (4 per year) contains information of a broader nature while the other issues will contain the technical information that our users expect. We’ll send every issue to our customers and the quarterly issue out to everyone. I hope you enjoy this change. Look for our first general issue story in the next edition where we will discuss flying an area of the Gettysburg Civil War battlefield with a set of drones for the National Park Service. Enjoy the start of summer!!

Monochromatic/Hillshade Displays in LP360
We have added a new monochromatic display mode in LP360 as well as rearranged the hillshade options to a more logical arrangement. A monochromatic display is just what it implies – a solid, single color display of all points regardless of attributes such as class or return number. This mode of display is ideal for hillshades where you wish to accentuate some aspect of the data. A classic example is to detect three dimensional attributes of the data within the 2D display. You could always achieve a monochromatic display in LP360 by trickery such as setting up a Live View filter of Returns with all returns coded to the same color. However, this was a bit inconvenient and a bit of an Easter egg.

DJI Drones for Mapping: DJI Phantom 4 Pro and the DJI Inspire 2
There are lots of drones to choose from for mapping purposes, but a couple of stand-outs from DJI are the Phantom 4 Pro and the Inspire 2. They both provide excellent flight times and they also have mechanical shutters. This is important to eliminate the geometric distortions inherent with electronic rolling shutters, which are typical in less expensive drones with built-in or custom cameras. They both can be flown for mapping type missions using DJI’s new Ground Station Pro application for iPad. The new app has lots of features that are perfect for collecting imagery for photogrammetric use. They are quite different in price and size however, so how do you choose?

Group Classification Tools Enable New Analysis Methods in TerraScan
Beginning in 2017, additional grouping tools were introduced to enable new methods of conducting above ground classifications, beyond the usual classification routines. These tools rely on group logic - grouping above ground points with probable relationships with the goal of designating a single group of points per physical object. In short, the usual classification routines classify individual points, but the grouping method enables classification on an object level basis. The end game of these new grouping tools is to become the preferred method for the classification of above ground features. The principles of this process and advantages are discussed in the previous group classification article. This article looks at a couple of tools to demonstrate where group processing is advantageous over routine point processing, particularly for providing new data analysis options.

Synchronize Views: Camera Options
TerraScan provides from the ability to synchronize MicroStation views by making one view dependent on a master view. The dependent view then updates when the master view changes. One advantage of this tool is that it allows the visualization of the same location using different attributes simultaneously, which can be extremely useful for quality assurance/quality control of point classification.

Welcome to the May 2017 edition of GeoCue Group News!
This is the time of year when we are thick into the development of additions to existing software and the creation of new products. On the LP360 front, we are adding some powerful new quality check tools for LIDAR (see the separate article in this issue on LAS File Analyst). We are rigorously testing GeoCue 2017 prior to release; there are some very useful new features such as the ability to archive projects. On the AirGon front, we are redesigning the AirGon Sensor Package (ASP) Suite to include tools for preconditioning data from low cost drones such as the DJI Phantom 4 Pro and Inspire 2 prior to processing in PhotoScan. We are exhibiting at Commercial UAV Europe in June and hope to see you there if you are attending.

Point Cloud Exploitation/UAS Metric Mapping
An Introduction to LAS File Analyst
In 2016 we added a very powerful new tool to LP360 (standalone version) called Feature Analyst. This is a tabular-driven tool that synchronizes a table view of Features, Feature Parts and Vertices with their graphical representation in the Map and Profile views. This tool has improved the creation, editing and quality checking of features such as breaklines by an order of magnitude.
We are now working on a new analyst tool for LAS files. LAS File Analyst is being created to satisfy the needs of our government customers who accept LIDAR data (e.g. the USGS, the USDA, USACE and so forth) as well as those who prepare LIDAR data for delivery to these agencies. Like Feature Analyst, LAS File Analyst is a powerful, tabular-based tool that will allow you to review, analysis and repair some LAS file issues.

TerraScan: Classify Groups
Beginning in 2014, some grouping tools were introduced to TerraScan. Those tools applied to mobile LIDAR applications as they were aimed at classifying moving cars and trees. In late 2016, additional grouping tools were introduced to enable a new method of conducting above ground classifications in airborne LIDAR datasets beyond the standard classification routines. Prior to classification, the software groups above ground points with the goal of designating a single group of points per object. Each grouping of points receives a unique identifying number and this number is assigned to each point. The assigned group attribute may be saved in the FBI format for future use. The end game of these new grouping tools is to become the preferred method for classification of above ground features.

The first four months of each year are the heavy trade show months. It has been good to see a lot of you at TRB, ILMF, SME, CONEXPO, ASPRS and other shows we have attended this past quarter. We still have a few more on the calendar such as the new Commercial UAV show in Brussels in June and, of course, the ESRI User Group meeting in July. We plan to release GeoCue 2017 sometime in this second quarter. It is code complete so we are now in the testing phase. GeoCue continues to be the only workflow management tool available for industrial strength LIDAR production. Of course, we are also deeply engaged in coding for the 2017.2 release of LP360. No rest for the weary!

A Comparison of Volumetric Workflows
In the last quarter of 2016, we introduced (under our AirGon brand) the Bring Your Own Drone (BYOD) Mapping Kit. This kit contains all the software one needs to turn a low-cost drone such as a Phantom 4 Pro or an Inspire 2 with x4s camera into a serious mapping platform.
Our presales technical team is sometimes asked the question “My application is fairly simple volumetric computations. If I have Pix4D or PhotoScan, why do I also need LP360?” My folks asked me for a quick summary to use when discussing this topic. I think it is a pretty good question and worthy of adding to our general discussion papers. This discussion is rather extensive but it does contain a summary workflow capabilities table at the end (Table 1).

Setting the USGS Overage Flags in TerraScan
For many years users have been working with the concept of ‘cutting overlap’ in LIDAR data production. With the onset of LAS v1.4 and the USGS LIDAR Base Specification, the way in which this concept is implemented has significantly changed. Specifically, USGS standards require a change in the way overlap points are managed and stored. Terms arise such as: ‘Flags’, ‘bits’, ‘overlap’, ‘cut overlap’, or ‘overage’. To help ensure that products generated using TerraScan meet USGS delivery standards, this article discusses the concept of ‘Overlap’ in the LIDAR industry, the USGS requirements for ‘Overage’ flagging, and how to QC the end-product to ensure compliance.

Restructuring the LP360 Product Family
When we began addressing the sUAS (small Unmanned Aerial System) market, we wanted to narrowly focus our LP360 tools for this specific market. We first introduced a variety of LP360 called LP360 for sUAS. We packaged this, built marketing material and the software setups to deliver the product. LP360 for sUAS was delivered as a Window’s only product.
We found this was causing a bit of confusion in the customer base already familiar with LP360. Folks wanted to know how this product differed from the other members of the LP360 family and so forth.

Reproject/Shift LAS Point Cloud Task in LP360
This workflow is for reprojecting or shifting, in x, y, and/or z direction, for LAS data. When a new project is created, LP360 attempts to set the SRS of the project using the first loaded file (i.e., LAS, raster, and/or feature files). If this cannot be done (for example, there are many LAS files with no defined SRS), the user should set one in 'Project Settings'.

This gives us the location of the AV-900 Survey System antenna to within a few centimeters relative to a local base station. This technique is commonly called Direct Geopositioning since, in theory, you can generate accurate mapping products with minimal ground control points.

Waveform Data in TerraScan
Many users of LIDAR use discrete return systems for their production, however, many systems are capable of capturing the full waveform of the energy returned from an outgoing laser pulse. The figure below illustrates a laser pulse directed through a tree. Different portions of the laser energy are backscattered/returned by various surfaces: branches, twigs, leaves, and hopefully the ground itself. In this example, the discrete return system recorded three returns, but a full waveform system would have recorded the continuous return of energy.

GeoCue Adds Project Archiving in v2017 Release
One of the common requests we receive from our GeoCue users is to add the ability to archive or off-line projects when they are completed. Once a project has been completed and fully delivered to the customer, it needs to be transferred effectively out of production operations to an enterprise data archive. Archiving a completed project frees critical IT resources such as primary disk storage and simplifies operational back-up processes while providing an auditable compliance trail for any corporate or customer-required data retention policies. It also reduces the burden on on-going production staff of having to maintain and track historical projects, often for years after they are completed, in your live production database. Archiving can also reduce your overall business risk by adding another layer of data loss prevention by archiving to an off-site facility or to the cloud.

Welcome to the November issue of GeoCue Group News!
We are enjoying some fabulous fall weather here in north Alabama. I feel sorry for you guys who are facing months of snow and slush!

We attended the Commercial UAV Expo in Las Vegas at the end of October. This show is hosted by Diversified Communications, the same group who hosts ILMF, SPAR and GeoBusiness. This was a terrific conference, dominated by participants interested in professional mapping and inspections with drone technology. While we cover the gamut of technologies in our AirGon business, we were primarily focusing on the BYOD Mapping Kit at this conference. I was pleasantly surprised by the number of surveyors who attended, all with a keen interest in adding drone mapping to their portfolio of technologies. I predict that in just a few years, there will be a drone of some sort in every surveyor’s truck.

Automatic Stockpile Toe Extraction
LP360 includes a Point Cloud Task (PCT) that will automatically digitize the toe of a clean stockpile and can allow for the classification of overhead structures such as conveyors. This tool saves considerable time when computing stockpile volumetrics.
A “clean” stockpile is one with a clear demarcation of the boundary from a 3D perspective that allows you to clearly distinguish the base at all points along the pile. On the other hand, sometimes a pile is ill defined, with close by vegetation and uneven terrain making distinguishing the base difficult. Our automatic stockpile toe extractor will not properly function on this type of configuration. The toe will have to be manually edited using Feature Edit tools.

A Quick Intro to Customizing MicroStation CONNECT
The biggest change when moving from one of the previous versions of MicroStation to CONNECT is that CONNECT is 64-bit program, allowing the advantage of access to more memory. Access to more memory enables Terrasolid to enhance their applications, and makes CONNECT much better suited for LIDAR and photogrammetric point cloud processing. The ribbon interface is probably the most noticeable change, however, the first thing that everyone always wants to do is to revert to the classic interface. This would be a big mistake as the usability labs have shown the ribbon to be the best interface. Hence, it is highly encouraged that all users investigate and get used to the ribbon in order to see the advantages.

What Miners Want
I attended the Commercial UAV Expo in Las Vegas at the end of October. I gave a talk entitled “Mine Site Mapping – One Year In.” This talk was on our experiences with performing mine site mapping services with our AirGon Services group. Our services group is primarily about Research and Development (R&D). We use our engagements with mining companies to discover the products that they need, accuracy levels and, most of all, how to reliably create these products. These experiences inform both the development of our technology (the MMK, Topolyst, Reckon, the BYOD Mapping Kit) but also help us develop best practices for both collection and processing.

Reckon Tonnage Workflocw
Calculating tonnage is a two-step process using Topolyst and Reckon. First, the density information must be formatted and entered correctly into the “Volume” file in Topolyst/LP360. This file can be named anything but for our instructions it is the Volume file you see in the figures below.
Secondly, Reckon will calculate the tonnage from the volume and density when uploading the volume file to Reckon. Once posted to Reckon, the density weights are displayed in Reckon and can then be downloaded to a .csv file or PDF report.

Welcome to the October issue of GeoCue Group News!
We held our annual training event for LP360 in September in our office training room. This year we had to turn away last minute registrations due to size limitations. It is really terrific that we have so much interest in this great product set. Next year we will move to a new, larger venue to accommodate the increased interest.
We have a new initiate with several US federal agencies to add new digitizing tools to LP360. Through a working group partnership, these new capabilities will be introduced to the standalone version over the next six months.
We will be releasing the 2016 version of GeoCue in this quarter. We have added full support for the CONNECT version of Terrasolid products as well as a new archive system to allow you to move historical projects out of the active database.
Look for our new low cost Bring Your Own Drone Mapping Kit, being released at the Commercial UAV Expo in Las Vegas at the end of this month. Through the BYOD Mapping Kit, we can help you collect serious mapping data with low cost DJI drones. Look for us there!

WMS Layers in LP360
WMS layers can be added into LP360 for ArcGIS, LP360, Mission Planner, LIDAR Server and Reckon. LP360 for ArcGIS, LP360 and Mission Planner all display WMS data as a layer. These different programs provide users the ability to display WMS data in a client application. LIDAR Server and Reckon both consume and produce WMS data, for instance a base map layer.
Client applications such as LP360 for ArcGIS, LP360 and Mission Planner can therefore display data from Reckon, LIDAR server as well as any base map which supports WMS. There are some base maps that are published using WMTS (Web Map Tile Service) which LP360 does not support so it is important to keep in mind the difference between the two.

Vertical Accuracy Reporting in TerraScan
GeoCue is a workflow management tool that by its very nature has some data management features to it as well. When working with files within GeoCue files are either stored on a network path that is referenced within the program or files are stored in the GeoCue warehouse. Projects may contain large quantities of data in many locations, which can be difficult to shift through when determining what is the correct data that needs to be delivered to a customer. GeoCue provides an Export Files command that can be very helpful and save the user time and help ensure the correct version of the data is delivered. The Export Files command gives the user a GUI to determining what files to export from entities in a GeoCue project, and where the files should be exported to, while using a robust copy utility to ensure data integrity.

Welcome to the September issue of GeoCue Group News!
Summer is over and now the pace picks back up (did it ever slow down – I missed that!). Our LP360 training event, scheduled for the week of September 12th, has sold out. We are considering a second session later on this fall where we will focus on drone-based data processing workflows. Drop us a line if you have an interest in this. We released GeoCue Service Pack 5, addressing a number of LAS 1.4 compliance issues. Between LP360/Topolyst and GeoCue, I think we finally have LAS covered! Everyone in the USA is now flying drones under the new Part 107 rules. For those of us focused on small area metric mapping, this has been a significant simplification in flying! Finally, on the AirGon side of things, we are wrapping up a new version of our Post-Processed Kinematic positioning system. The results thus far have been stellar – stay tuned!

Tips for Defining Stockpile Toes
We have added quite a few tools to LP360 (Standalone)/Topolyst aimed at small unmanned aerial systems (sUAS) data processing (and small area LIDAR, of course). Here are a few tips for defining stockpile toes for volumetrics computations.
You will note that the automatic toe extraction Point Cloud Task (LP360 Advanced or Topolyst) has an option for Overhead Points. When selected, this algorithm attempts to segregate overhead points from stockpile points. The classic example, of course, is an overhead conveyor. It is important to note that checking this option when you do have overhead structures aides the algorithm in finding the toe, even if you are not interested in classifying the overhead points.

Vertical Accuracy Reporting in TerraScan
In November 2014, the American Society for Photogrammetry and Remote Sensing (ASPRS) released an updated standard, Positional Accuracy Standards for Digital Geospatial Data, to tie together past experience with current industry practice of preparing data, but not plotting the resulting maps. The new standard provides guidelines for calculating both the vertical and the horizontal accuracy. Prior standards include the National Map Accuracy Standards (NMAS), which were developed in 1947, the 1990 ASPRS Accuracy Standards for Large-Scale Maps Standards and 2004 ASPRS Guidelines, Vertical Accuracy Reporting for Lidar Data. None of the previous standards was designed to address the current technologies available for LIDAR, orthoimagery or digital camera mapping. The 2014 ASPRS Standards, were therefore created to help address the new technology. The new standards focus on the higher levels of accuracy that are currently available using the latest technology.

This has been a very busy time for our AirGon subsidiary. While our primary focus is delivering hardware and software tools for high accuracy drone mapping, we also provide a limited amount of services. These services have been extremely helpful in providing a test bed for our positioning and processing tools.
We continue to test and provide feedback to our LP360/Topolyst software development group regarding tools for improving the overall workflow experience. We run in to all sorts of complex modeling situations and we try to assess each in terms of tools that would ease and/or improve the workflows. For example, you will see a new tool to extract 3D vertices from line work in the latest EXP release of Topolyst/LP360 (standalone). This tool has been added to assist with modeling Low Confidence Areas (LCA) common to point clouds derived from Structure from Motion (SfM) algorithms.

We had a very busy July. We put the finishing touches on our initial release of Topolyst and have already started on the next set of features. We received the latest version of our AirGon designed RTK board back from manufacturing and have had very successful initial testing on the AV-900 hexcopter. We have released a GeoCue Service Pack to select beta testers that incorporates all of the byzantine requirements for WTK coordinate reference system population in version 1.4 LAS files. Finally, we are doing more and more in Amazon Web Services. We will soon be releasing a test version of GeoCue that allows direct archiving to AWS Glacier. Stay cool!

Analysing Swath Coverage in LP360
Quality control and assurance checks should be applicable for various acquisition scenarios so as to not limit the methods that a data provider may use to obtain usable data. In that regard, some providers use collection methods that require multiple overlapping swaths in order to adhere to the project requirements. In other cases, simple side overlap to ensure there are no holes in data coverage suffices. Here, we will present some methods for analyzing collections to validate if the collection matches the intended flight plan.

Geiger-Mode LIDAR Workflow Review
Geiger-mode lidar data is getting a lot of press lately as the “next big thing” in airborne data collection. Unlike traditional lidar sensors, which we will call “linear-mode lidar” for convenience, Geiger-mode sensors use a different detection method in the receiver – the “Geiger-Mode” part – to enable much higher data collection altitudes and higher resolutions than traditional sensors. Harris Corporation has been providing Geiger-mode lidar data to various US government agencies to validate the accuracy and cost-effectiveness of this technique for mapping applications. If you are interested in the technical aspects of what makes Geiger-mode different, there were several excellent papers on the technology at this year’s ILMF conference.

The AirGon Sensor Package, Revision 3
When using imagery as a source of metric measurement, an up-front task that must be accomplished is determining the exact position (X, Y, Z) and orientation (Pitch, Yaw and Roll) of the camera at the precise time of each image exposure. This seven tuple of data is termed the dynamic exterior orientation (DEO or often simply EO) where time (the first of the seven parameters) is usually provided (but not always‼) by some external event such as a camera trigger. There are a number of algorithms for determining the position and orientation of the camera that require various external information such as known positions on the ground.

Welcome to GeoCue Group User, July 2016!
Welcome to the July edition of GeoCue Group News. I hope all of you in the USA had a terrific 4th of July holiday.
We have been very busy preparing our initial release of Topolyst™, our LP360-derived product aimed at the small Unmanned Aerial Systems (sUAS) market. We will be making the release in July. The work we have been doing with drone services has really informed this product. I think our initial release will have an immediate positive return on investment. Note that our experimental release of LP360 (Windows standalone version) Advanced has the same features as Topolyst so those of you who own Advanced will be receiving the same functionality. The other big news is the release of new sUAS rules by the Federal Aviation Administration (FAA) for those flying in the USA. Please see our article in the AirGon section of this issue for details. Have a great July!

Exporting GeoTagged Screenshots and Generating a package for Google Earth
A new feature added as of TerraPhoto 015.005 (CE and v8i/v8) provides the ability to export rendered views in a TIFF+GeoTag file format. These images can then be bundled in a package that can be displayed within Google Earth. In this article, we will walk through this process using Danger Points in a power line workflow as a use case example.
Rendered Views
The first step in the process is to create rendered views of the objects, Danger Points for example, that will be included in the Google Earth package. Within TerraPhoto’s general settings tab, activate, or add and activate, the coordinate system that corresponds with the data being used, in this instance Swedish RT90. The coordinate system is necessary so that TerraPhoto can determine the geographic coordinates to assign to the image for display in Google Earth. Next, open TerraPhoto’s Manage Raster Reference and load the orthophoto into View 1 only.

River Flattening in TerraModeler, Part II
In the January 2016 Newsletter, we presented one way to accomplish river flattening using TerraModeler. In this article, we introduce an updated approach to this process, which should be more efficient.
Hydro-flattening is a common requirement when it comes to delivering surface models to the U.S. Geological Survey (USGS) National Elevation Dataset (NED). According to the USGS LIDAR Base Specification version 1.2, a hydro-flattened surface refers to a specific kind of digital elevation model (DEM) that is required for inclusion in the NED. Hydrologically flattened waterbodies, streams, rivers, and other water surfaces should be flat and level from bank-to-bank. Rivers and streams should follow a downhill water surface, which would reflect the more natural behavior of the environment.

Liberalizing Drone Flights - FAA Part 107
New regulations for commercial small unmanned aerial systems (sUAS or “drones”) will take effect in the United States on August 27, 2016. These new rules, referred to as Part 107, contain a real gem that not many folks are discussing. In fact, I think it may be the most important rule of the entire Part 107.
First of all, a very, very big caveat‼ I am not a lawyer nor a pilot so take everything in this article with a big grain of salt. I am not responsible for misinterpreting Part 107 and I won’t come visit you in jail! After all, if you have read it cover to cover (as I have) you will realize it is not the easiest document to summarize!
Our subsidiary company, AirGon LLC, has an FAA 333 exemption to commercially fly sUAS. We have spent tens of thousands of dollars on private pilot training for our field service technicians over the past year. While the requirements for piloting an sUAS are greatly simplified in Part 107, they are not quite as simple as was presented in the original FAA Notice of Proposed Rule Making (NPRM). The term Pilot in Command (PIC) remains (a new classification called Remote Pilot) and the testing (for those who do not already have an FAA airman’s certificate) cannot be done online. Still, this is considerably less expensive and less nonsensical than the current 333 rules.

Classify by Statistics is a Point Cloud Task in LP360 that can be created by selecting the “Add Task” option under the Point Cloud Tasks menu. Classify by Statistics is primarily useful for general data thinning – especially useful for very dense data such as that derived from imagery (dense image matching, DIM, data). For example, you can set the grid size to 2 meters and choose a median selector, such as one point. You will then have a 0.5 points/m2 point cloud based on the median points from the dense data.

Cleaning up Ground Classification
After LIDAR data has been collected and delivered to the processing office one of the first steps, after quality control and calibration, is to run classification routines on the data. There are multiple classification routines, which may be used depending upon the final delivery results of the data, however generally a ground classification routine is always run.
The adaptive TIN ground filter is designed to classify a ground surface from the LIDAR data. Depending upon the parameters used during the classification process, as well as the LIDAR itself, it is possible that there will be patches of ground surface that do not end up being classified. Usually features with sharp elevation changes. Some common examples of missing ground classification includes: earthen berms, cliff sides/tops, hilltops, elevated road surface.

Redlining in Reckon!
AirGon Reckon (“Reckon”) is our cloud hosted collaboration portal for small Unmanned Aerial System (sUAS) or “drone” mapping. It has been designed from the ground up for scalability in the cloud. Hosted in Amazon Web Services (AWS), it provides a robust platform for sharing data that requires no administration or infrastructure on the user’s part including that dreaded operation of data backups!
Reckon is designed to accommodate companies that wish to manage data for multiple sites (of course, just a single site is fine, as well!). It is suited to any of the various deployment models including owner/operator, service provider or any combination of the two extremes. Once a company has a Reckon subscription, they can easily establish a location for each of their physical project sites. A physical site might be a quarry site, a stockpile yard, a borrow pit or any other area that will be routinely monitored. In Figure 1 is depicted the physical sites associated with the Reckon test login. Thus you can imagine these as the four sites being managed by the AirGon Reckon Company. You can explore this yourself at www.airgon.net.

sUAS Deployment Models
We have invested a tremendous amount of resources (monetary, development, knowledge) into developing technology and services for mapping sites using dense image matching collected with small Unnamed Aerial Systems (sUAS). Our focus is applications suitable for an sUAS (non-populated areas, smaller sites) that require near survey grade accuracy. The most common example is small open pit mine sites such as quarries. We have not considered agricultural since these tend to be very large areas where radiometric analysis is the focus rather than geometric correctness.
Like most other companies involved in this emerging market, we are trying to predict the most palatable business model. However, I would say that unlike many other technology providers, we are seeking the business model that makes the most sense for the customers, not for us.

River Flattening in TerraModeler
Hydro-flattening is a common requirement when it comes to delivering surface models to the U.S. Geological Survey (USGS) National Elevation Dataset (NED). According to the USGS LIDAR Base Specification Version 1.2, a hydro-flattened surface refers to a specific kind of digital elevation model (DEM) that is required for inclusion in the NED. A hydrologically flattened waterbody, stream, rivers and other water surfaces should be flat and level from bank-to-bank. Rivers and streams should follow a downhill water surface, which would reflect the more natural behavior of the environment.

Welcome to the December issue of GeoCue Group News
Well, like everyone is saying, I cannot believe that 2015 is drawing to a close. Where did the year go? This will be a short note – I have to get some Christmas shopping done!
We finally released LP360 this past week. Our early postponement was to squeeze new features into the products whereas the later delays were to ensure stability. We have been using the products in our internal production processes for the past few months. This has been a great experience in terms of fine tuning features and monitoring stability.

Horizontal Accuracy Reporting in Terrasolid
In our previous Newsletter we talked about Horizontal Accuracy Reporting and the new standards put forth by the American Society for Photogrammetry and Remote Sensing (ASPRS), Positional Accuracy Standards for Digital Geospatial Data, in November 2014. The updated standards were designed to tie together past experience with current industry practices for preparing data. The new standard provides guidelines for calculating both the vertical and the horizontal accuracy and focus on the higher level of accuracy that are currently available using the latest technology.

Welcome to the November issue of GeoCue Group News
First of all, I have to apologize for us not releasing LP360 at the end of October as I promised in the last issue! We needed to add a feature to LP360 to assist with very dense data sets. This new “Classify by Statistics” point cloud task can be used for a variety of functions, among them data thinning. We also took the time to tune a number of different performance bottlenecks, including clipping contours to a project boundary.
We have entered the services business in a small way. We have encountered a number of mine operators who want to collect maps and volumes of their sites using small unmanned aerial systems (sUAS) but they are not yet ready to internalize the process. To assist with this transition, we now offer flying and data processing services to these customers. We do the bulk of this production in LP360 with a bit in our GeoCue workflow products.

Horizontal Accuracy Reporting in LP360
In November 2014, the American Society for Photogrammetry and Remote Sensing (ASPRS) released an updated standard, Positional Accuracy Standards for Digital Geospatial Data, to tie together past experience with current industry practice of preparing data, but not plotting the resulting maps. The new standard provides guidelines for calculating both the vertical and the horizontal accuracy. Prior standards include the National Map Accuracy Standards (NMAS), which were developed in 1947, the 1990 ASPRS Accuracy Standards for Large-Scale Maps Standards and 2004 ASPRS Guidelines, Vertical Accuracy Reporting for Lidar Data. None of the previous standards was designed to address the current technologies available for LIDAR, orthoimagery or digital camera mapping. The 2014 ASPRS Standards, were therefore created to help address the new technology. The new standards focus on the higher level of accuracy that are currently available using the latest technology.

Welcome to the September issue of GeoCue Group News
We have had a lot of things going on in August from finalizing a new client interface for LIDAR Server to receiving our Section 333 Exemption from the FAA. In addition we have started a new workflow integration project that will see a major image processing system hosted in Amazon Web Services (AWS).
In addition to a number of new software developments, we are embarking on offering cloud-hosted subscription services in several different areas. Earlier this year, we introduced Reckon, our AWS-hosted data management and access system for stockpile volumetrics and mine site mapping. This is a subscription services based on sites and data volumes. It relieves local quarry owners from the burdens of managing on-promises servers for housing digital mine site mapping data.

LIDAR Server as a Service
We have now decided to offer LIDAR Server not only as an on-premises solution that users own and operate but also as a subscription model hosted in Amazon Web Services.
We have just completed a major upgrade to LIDAR Server, our solution for hosting, viewing and delivering LIDAR data. Depicted in Figure 1 is the recent LIDAR data set for Davidson County, Tennessee (Nashville) presented in a zoomed out view of the new JavaScript LIDAR Server client. This is a beautiful Quality Level 2 (QL2) data set provided to us by the USDA (a user of LIDAR Server).

Recognizing Misalignment Patterns for Airborne LIDAR System Calibration
In order to accurately complete an aerial LIDAR survey it is important that the sensor is properly calibrated. Airborne LIDAR calibration can be a complex and daunting task. TerraScan and TerraMatch are a wonderful toolset to assist the analyst in determining and correcting these systematic errors. While the program can be operated much like a black box solution, it’s always helpful to understand what one is observing in order to get the best answer. I like to use the analogy that TerraMatch is like a calculator – the answer it gives depends upon the input you give it. Or the more colloquial expression, “garbage in, garbage out”. Hence, I always try to stress the importance of understanding one’s dataset in order to calibrate the best data for the end user. Read More

Welcome to the July issue of GeoCue Group News
Welcome to the July issue of GeoCue Group News. I spent the week of the Fourth of July at my beautiful retreat on the lovely Tennessee River, ostensibly on holiday. In reality, I was sitting with my laptop at the kitchen table writing magazine articles. I am not complaining, though – the view is fabulous!
I was also very busy delaying our experimental release of LP360. I did a complete run-through of our new Live View display filter, sending multiple suggestions for tweaks to the development crew and testing out their new builds. On some days we cycled three builds! This is a real advantage of working from Casa Rio. If I were at the office, they would probably knock me in the head! The effort will be worthwhile – this has turned out to be a very nice tool for quickly modifying the display of point cloud data. Read More

LIDAR Quality Levels – Part 1

Welcome to the June issue of GeoCue Group News
I am looking for the month of May – it seems to have disappeared without a trace!
We recently visited with the Tennessee Office of Information Research (OIR) in beautiful Nashville, Tennessee. The OIR is the coordinating state agency for a USGS 3DEP LIDAR (3 acronyms in a row – not quite a record!) acquisition project. Under this program, the state of Tennessee will be flown at Quality Level 2 (2 points per square meter) over a four year period. The initial collection (slated for this fall) will encompass some 11,500 square miles, covering 27 counties. Read More

Spatial Density Distribution
Quality control and quality assurance checks for LIDAR data continue to evolve as the industry identifies new ways to help ensure that data collections meet desired usage requirements. The U.S. Geological Survey (USGS) LIDAR Base Specification introduced a definition for spatial density distribution and regularity within LIDAR data. The requirement is that the spatial distribution of usable points shall be uniform and regular. LIDAR data by nature is not a gridded surface, but a series of random points. To best approximate a uniform surface it is recommended that LIDAR collections should be planned in such a manner as to produce a first return point cloud that comes close to a regular lattice of points.Read More

A license of ArcGIS is required for this session and will need to be provided by the attendee. Register

Letter from an LP360 User
We recently received this letter from one of our LP360 customers who has discovered how useful our Knowledge Base can be. Thank you Gordon for letting us share this with our readers and for being an LP360 customer! If you have not checked out our Knowledge Base please do. Also, we would love to get your feedback good, bad or otherwise. You can send comments to me at ngraham@lp360.com.
Hi there Karrie-Sue,
I just wanted to say how wonderful the LP360 projection tasks are. Without it we would have been stuck in a task we've recently delivered on. A client wanted to have their data from us in a coordinate reference system that was no longer used. Our point cloud from the photogrammetric software comes out in a couple of standard reference systems, mainly Transverse Mercator (such as the New Zealand Transverse Mercator). So, I am thinking, how on earth can I transform our point cloud to the format they require? Answer: LP360. I searched the knowledge base and applied the LP360 for ArcGIS tools accordingly. Our point cloud was first given a coordinate reference system and then transformed to the client's requirements. Job done, and it could not have been easier thanks to the hard work you put into LP360.
We flew the task last Thursday, 1600+ images at 36MP, 21 GCP, over a very deep quarry, delivered yesterday to a very happy client.
Kind Regards,
Gordon Morris

Welcome to the May issue of GeoCue Group News
We have been very busy this first third of 2015 with software development (as we always are). The thing about software is that it is never static. It is either undergoing new additions or entering the end of life phase. We have had a very big focus on ensuring that our products are optimized for LAS 1.4 support as this is the new requirement of the USGS. Additionally, we like to use LAS 1.4 in our mine site workflows since it supports a few nice capabilities that were not in LAS 1.3. Read More

Generating Low Confidence Polygons
In the new ASPRS Positional Accuracy Standards for Digital Geospatial Data, low confidence areas within LIDAR data are defined to be where the bare earth model might not meet the overall data accuracy requirements. Generally speaking with LIDAR data this can occur where there is heavy vegetation that causes poor penetration of the pulses. If the Vegetated Vertical Accuracy (VVA) cannot be met then low confidence area polygons should be created and explained within the metadata.Read More

What’s New in Terrasolid over the past year?
Unlike most software vendors Terrasolid makes progressive releases of their software modules over the course of a calendar year. The calendar year in turn corresponds directly with the maintenance cycle for the products. Hence, once a year all users must renew their maintenance and move on to the current year major release (for example, v015 for 2015) prior to the March 31st license expiration. The end of March expiration is simply a means of providing an overlap period between the expiration of maintenance on Dec 31, 2014 and the release of the v015 software and licenses. Read More

Using LP360 and LIDAR to Capture Building Heights for the City of Franklin, TN
Using tools such as aerial photographs and the global positioning system (GPS), the GIS team gathers and processes spatial coordinates, topology and dimensions of fixed physical objects such as buildings, rivers and roads, and translates the raw data into usable information. Combined with a strategic vision, this data provides a powerful system capable of analyzing complex information regarding our physical environment.

Working with LAS v1.4 Files
It is the end of January, it is cold outside and ILMF is less than a month away. What better time than now, I thought, to write about an exciting topic like binary data file exchange format conversions and the intricacies of setting upper bits in the classification bytes as attribution flags. My wife also tells me I need to get out more. But I digress. As our GeoCue users already know, we recently added support for v1.4 of the ASPRS LAS data format to GeoCue 2014. If you are involved in LIDAR workflows in North America, you will immediately understand the value of supporting LAS Version 1.4, Point Data Record Formats (PDRFs) 6 through 8. These are the required deliverable formats for the United States Geological Survey (USGS) 3D Elevation Program and any other projects following the USGS LIDAR Base Specification1. Of course, this will drive all standard LIDAR deliverables in North America so it will be critical to move to the new PDRFs available only in LAS version 1.4. Read More

Did You Know...

The recent service pack release of LP360 for ArcGIS, version 2014.1.51.1, now gives a Windows© user with even just basic permissions the ability to change the LP360 license level if all licenses at the currently desired license level in the LP360 License Administrator are unavailable. Read More

The No Point option is gone! Why?
With the latest release of LP360 (2014.1) the No Points option is no longer a selection in the LIDAR Layer Draw Tools legend. A no points display is now accomplished by simply toggling the Display Legend button on or off (Figure 1). This is also the case for the 3D View, the Profile View, and the Preview Window and is also a new feature for these windows as it was not an option in previous versions of LP360. Read More

Welcome to January GeoCue Group News
A Happy New Year to all of our newsletter recipients. Hard to believe that we have started 2015 but here we are! Will this be the year for a resurgence of United States infrastructure spending? Some folks seem to think so as indicated in this recent article in the New York Times: http://nyti.ms/1BlfK1w. Reduced gasoline prices, if they are sustained through 2015, will be a bit of a bonus to individual persons and indirectly stimulate government tax revenues. This is based on the fact that most gas taxes are per gallon of gasoline/diesel so changing oil prices do not affect this tax but as consumers spend their savings in other places, those places are invariably taxed.

Volumetrics – Do it Right!
We have more and more customers computing volumetrics using LP360 in combination with point cloud data sets derived from Dense Image Matching (DIM). Note that I will use DIM to mean both the process of generating a point cloud from a dense set of overlapping images as well as the product point cloud itself. Thus a DIM is a point cloud derived from a dense image matching process such as Pix4D or Agisoft’s PhotoScan. We have discussed the process of performing volumetric analysis in previous versions of GeoCue Group News (and, before that, in LP360 News). In this article I want to address the criticality of quality inspecting the DIM and classifying such that features not intended to be included in volumes, aren’t. Read More

Why Direction Matters when Digitizing Polygons in LP360
When drawing polygons it definitely matters if they are drawn clockwise or counterclockwise. Why you ask? Well, because polygons have a “sense” of direction. The right hand side of the vector used to draw a polygon is considered to be the “inside.” If you draw your polygon clockwise the right-hand side of the vector becomes the “inside” of the polygon. Likewise, if you draw the polygon counterclockwise the right hand side of the geometry is on outside of the polygon and the insider portion is now considered to be a “hole” (Figures 1 & 2).

Using GeoCue to Better Manage Your LIDAR Workflows
When we first launched GeoCue 10 years ago, we decided to target the rapidly growing airborne LIDAR production space as the beachhead for our workflow optimization and production tracking tools. It was an ideal fit; LIDAR “shops” were expanding rapidly, the technology was making great strides in developing new paradigms in existing markets while also opening-up new markets and application areas. The second wave of service providers were buying hardware and entering the market, driving competition and pricing. Top-tier engineering firms were beginning to bring the technology in-house. Demand for LIDAR data was actually exceeding the ability of the industry to supply it effectively. It seemed almost everybody was new to the technology and, for better or worse, learning as they went. It was an excitingly chaotic time. Read More

I am writing this having just spent a week helping get the V2014 release of GeoCue out the door – bugs, we don’t need no stinkin’ bugs! – so it may seem strange to immediately start talking about the future. But just as you constantly review your own best practices and production tools (Right? Right?), we know it is never good to rest on our laurels. The geospatial industry is changing too rapidly and has become too competitive to ever think that “what we have now is good enough” is a winning strategy for long-term success.
