GeoCue Group’s reference library articles covering a wide variety of geospatial topics related to our various product lines.
A bench test is a quick way to test functionality and collect diagnostic information about a True View system without mounting it to an aircraft. ITEMS NEEDED True View system True View Battery UMS Antenna Mast with coaxial cable GNSS antenna Controller Box CAT6 Controller Box cable RUNNING THE CYCLE Set up the True View unit…
Contours can be generated from a TIN surface at specified intervals. The contours are saved to one of the three following file formats: shapefiles, DXF, or DGN. Contours are stored as 3D polylines for DXF and DGN file formats. You have a choice to save polylines as 3D or 2D when exporting to shapefiles, where…
The True View 250 Hardware Users Guide covers the ins and outs of installing and operating the True View® 250 2DIS. Updated for firmware v3.0.5. The True View® 250 features dual GeoCue mapping camera with a 120° fused field of view for efficient and accurate photogrammetric data collection in a 1 kg package. The system is currently compatible with…
A common practice amongst GeoCue customers (and internally) is to use previously established control points to compare with an sUAS produced point cloud to gather absolute accuracy statistics. The vertical mean error from these statistics is often used to “Debias” a dataset. This is simply shifting the point cloud data to match the measured control…

Abstract In late 2009, a $14.3 million allocation from the “American Recovery and Reinvestment Act” for new light detection and ranging (LIDAR) elevation data prompted the U.S. Geological Survey (USGS) National Geospatial Program (NGP) to develop a common base specification for all LIDAR data acquired for The National Map. Released as a draft in 2010…
LASer (LAS) File Format Exchange Activities What is the LAS Format? The LAS file format is a public file format for the interchange of 3-dimensional point cloud data data between data users. Although developed primarily for exchange of LIDAR point cloud data, this format supports the exchange of any 3-dimensional x,y,z tuplet. This binary file format…
After updating/upgrading a program, double-clicking the shortcut fails to open and gives this dialog shown in figure 1, stating, Problem with Shortcut: The parameter is incorrect.”. What is the target (right click the shortcut > properties) for the shortcut? This can also be found going to “Open File Location” in the context menu. You can…
Introduction to Part 3: In the last part of this series, we discussed in some detail how a Triangulated Irregular Network (TIN) can be constrained by features external to the point cloud model such as lines, points and polygons. In this month’s edition, we will look at contours and how LP360 can extract elevation information…
This article is a continuation of the discussion of breaklines in LP360 (the standalone version). In last month’s installment, we discussed the overall concept of data modeling, especially the Triangulated Irregular Network (TIN). In this installment, I will discuss the general concept of adding constraints in the form of breaklines to these models. In future…
