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 - 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. The end purpose of this month's column is to implore the service and equipment providers to clearly communicate to clients the capabilities of systems in a vernacular that is understandable by the client.

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. Continuing in this same vein let me discuss so-called "Open Source" software. The impetus for this is a sudden increase in confused noise regarding work done by the American Society for Photogrammetry and Remote Sensing (ASPRS)'s LAS Working Group.

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 - I am treading down a dangerous path, speaking about design! My wife Nancy has a formal education in industrial design and often comments about my lack of ability in this department! Nevertheless, I venture forth.

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. Meanwhile, hobby versions (technically identical to the commercial versions, in many cases) are flying off the shelf as more and more casual users realize the fun of flying and photographing.

For reasons explained in the LP360 section of this month’s newsletter, we have reverted from the Topolyst name back to “LP360 for sUAS.” I apologize for all the confusion but the good news for those of you with Topolyst, you will be getting a bit more value under the new scheme.
I hope you will join us at the ILMF and/or SME conferences in Denver next week and the ASPRS conference in March. There is really a renaissance occurring within the ASPRS – please show your support for this critically important organization by attending the Baltimore conference in March.
We are releasing the 2017.1 version of LP360 either at the end of this week or the beginning of next week. This is an extremely powerful release that provides a lot of new functionality regardless of your application area. We have also done some performance enhancements to the Map View of LIDAR Server – check out a live version at www.lidarserver.com.
Have a great February!

Blast to the Past!
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'.

A Framework for Control Strategies
We do a significant amount of Research and Development (R&D) in drone mapping. Our AV-900 rotary wing system has an L1/L2 Global Navigation Satellite System (GNSS) that we run in the Post-Processed Kinematic model. 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.

Welcome to the January issue of GeoCue Group News!
I hope everyone had a relaxing holiday season and you are now ready to jump in to this new year.
January starts out very busy for us. First of all, we will be releasing new versions of LP360/Topolyst and GeoCue in this quarter. We changed our version numbering scheme to more accurately reflect when we release software rather than when we do the work for the release. We will now move to a Q1 (and Q3 for software with twice per year releases) schedule. LP360/Topolyst will release this month as version 2017.1. We will also be releasing a new version of GeoCue this quarter (2017).
We have a lot of exciting things going on from new software features to a new rationalization of our AirGon business.  Check out these and other topics in this issue. 
As always, we sincerely appreciate your business.  We look forward to doing great things together in 2017!

Thinning Feature Vertices in LP360 and Topolyst
We have lot of LP360/Topolyst customers with a variety of disparate feature collection and editing needs. To begin to address these needs, we introduced a completely new set of Feature Edit tools in the 2016/2017 releases of LP360 (standalone) and Topolyst. Last month I introduced the new Feature Analyst tool that will be available in LP360/Topolyst 2017.1 (As mentioned in the beginning of the newsletter, we reset our version numbering scheme, moving the December releases to January). These new versions are slated for release on 23 January (yes, of 2017!).

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.

Terrasolid Licensing for v017
Happy new year! With the new year upon us we want to provide some important information about the Terrasolid product licenses. Each year Terrasolid releases a major version change. Note that this isn't a major release in the traditional sense as Terrasolid releases incremental releases of the software packages on a continual basis which add new features, fix bugs and makes modifications to existing features. We have already seen a number of new features and capabilities enabled by the move to the 64-bit MicroStation CONNECT and PowerDraft CONNECT editions during the past year.

Welcome to the December issue of GeoCue Group News!
I know I say this every year but I really cannot believe we are already well in to December - this year simply vaporized! We are very busy wrapping up final features in our GeoCue and LP360/Topolyst product lines for the 2016 releases. As usual, I am trying to edge in a few last features so the releases may slip in to January 2017 (don’t tell our developers that I said this!). We have a lot of new, important stuff in both product lines so, as usual, you will be receiving considerable value for your maintenance dollars. From all of us at GeoCue Group, we wish you a peaceful and reinvigorating holiday season.

Feature Analyst is an exciting new tool that will appear in LP360/Topolyst 2016.2. To motivate this discussion, I will provide a synopsis of a few use cases for Feature Analyst here. A detailed look at these cases is presented at the end of this article.
We have been working with a small group of customers (primarily from the US Government) who do a lot of feature collection from LIDAR-based data sets. This work is primarily in support of hydrological modeling but can also encompass planimetric mapping operations. The group forms what I call the “LP360 Advisory Group” or “LAG.” This group advises us on capabilities for our software that will make a significant positive impact on their work.

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.

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.

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.

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.

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.

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.

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.

Our amendment adds all current and future 333 approved aircraft to our 333. AirGon can now fly any sUAS that has ever been approved by the FAA as well as all future approved systems. This list currently contains 1,150 different sUAS (AirGon’s own AV-900 is number 207 on the list). This provides us a lot of flexibility in working with clients; for example, in situations where a glider sUAS is more efficient than a rotor craft.

Welcome to GeoCue Group User, April 2016!
Welcome to the April 2016 issue of GeoCue Group News. Looks like we have made it through another winter (OK, I know there is not a lot of sympathy from you northern folks!).
We have been busily preparing for our first software releases of 2016. We have a service pack for LP360 that addresses a few issues that slipped through the cracks with the 2015.1 release. We are working on adding 64 bit MicroStation support to the GeoCue LIDAR 1 workflows to support the new edition of Terrasolid products. We will soon be releasing this as GeoCue 2016.1. Finally, though we are not exhibiting, we will be attending the 2016 ASPRS conference in Fort Worth this month. We hope to see you there.

Using the Classify by Statistics Point Cloud Task in LP360
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.

Creating a Profile in LP360
There are two ways to draw a profile cross section in LP360. The most commonly known way is to left-click on a point to start the profile, draw the length and left-click again to specify the end point of the profile. To specify the depth at that point, left-click and drag the profile to the desired width. If you wish to use a depth that was used in a previous profile, double left-click.

Welcome to GeoCue Group User, March 2016!
Welcome to the February 2016 issue of our User Newsletter. As I mentioned in the January issue, we are now focusing our newsletter toward customers of GeoCue Group (including AirGon) products and using other means (such as the blog) to convey information that is not specific to GeoCue technology. Too late I realized that this gives me an additional writing task each month!
In a recent survey, we asked you (among other things) how you stay up to date on technology. A surprising number of you said “print media.” At the bottom of the methods were Twitter and Facebook. I suspect one reason is that many employers block these types of communication channels. Another high ranking method are shows and conferences. Anyway, more on this in an upcoming edition. Enjoy!

Classifying in LP360 Using the Number Keys
When classifying within LP360, the numbered keys on the number pad section of the keyboard can be used to specify and commit points for the “To” class during the classification process. However, the numbered keys across the top of the keyboard cannot be used for this shortcut.

LIDAR Production Solutions
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.

Welcome to GeoCue Group User, March 2016!
Welcome to the March 2016 issue of the GeoCue Group Newsletter. An early spring seems to be upon us in the South (since I have said this, it will freeze next week!). The band of leaf-off but no snow weather is rapidly shifting north; a busy time for the flying companies.
We have been doing a tremendous amount of work with accuracy considerations, both in traditional LIDAR and in sUAS mapping. As I review processes and new techniques, I find myself more often than not using the National Geodetic Survey website (www.ngs.noaa.gov) as a rich resource of information. Documents and procedures at the NGS span both the theoretical and practical issues involved with GNSS surveying. The NGS is truly a national treasure - Check it out!

Terrasolid v016 Release
In the middle of February Terrasolid released the v016 products. This is in line with their usual modus operandi of releasing a major version update which corresponds with the current calendar year. The calendar year is the maintenance period on Terrasolid products, save for a few unique user situations. This process should be familiar for long standing users of the product line who have renewed maintenance each year, granting them access to the latest versions plus ongoing support for the products. The release of the v016 products is, for all intents and purposes, simply a part of the maintenance licensing process, as Terrasolid releases continual updates to their software over the course of the year.

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.

Well, first of all, Happy New Year! May you have a happy and prosperous 2016!
As I mentioned in the December 2015 issue of our newsletter, we are streamlining and focusing our business this year. One of the things we are changing is this newsletter. We were trying to reach way too many disparate audiences and not being effective with any, I fear. We included general industry information related to the geospatial arena, aimed at decision makers. In the same issue, we included tool tips for LP360. This is just too broad.

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.

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.

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.

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

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

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

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

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

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

Coordinates, Coordinate Systems and LIDAR Data (Part 3)
In the previous articles we provided an introduction to coordinate systems, geoids, datums and projections. This background information was needed in order to delve into more details on transformations and changing projections in the various software packages to help you do more with LIDAR data. This article will provide the information into transformations and changing projections within LP360, GeoCue and Terrasolid. Read More

December 2014

Welcome to December GeoCue Group News
I hope all of our USA customers had a great Thanksgiving holiday. It is hard to believe that we have already slipped into December! In November we released GeoCue 2014.1 and (for Hexagon) the latest edition of Digital Mapping Camera Post-Processing System (DMC PPS) software. Added to the release of LP360 2014.1, this completes the new software releases for calendar year 2014. Of course, we are already busy on the next versions – software is never really done! Read More

GeoCue V2015 and Beyond
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. So as we head into 2015 we want to talk about what comes next for GeoCue. This is a conversation we have with ourselves every day, but it is also one that we want to include you, our customers, in to a very large degree. Read More

Coordinates, Coordinate Systems and LIDAR Data (Part 2)
In the previous article, we briefly mentioned coordinate systems while looking at how they played a role when defining the MicroStation design cube and setting up the Terrasolid software. A brief mention was fine for that setup, but if we wish to delve into more details on transformations and changing projections in the various software packages to help you do more with LIDAR data, then it is helpful to start with some of the basics. As such, this article will provide an introduction to coordinate systems, geoids, datums and projections. Read More

Shortcut Functions for Contour and Intensity Settings
With the newest release of LP360 (2014.1) we added shortcut functions for the Contour and Intensity buttons. Now, to easily get to the symbology adjustments for these features you can simply click the Contour or Intensity button while holding down the Ctrl key. These two buttons are located on the LP360 Toolbar. Read More
