GeoCue’s repository of TrueView tools, tips and workflows for the TrueView line of drone mapping products. Includes former AirGon products such as Loki and ASPSuite.
Problem: LP360 Errors when trying to run a Point Cloud Statistics Extractor PCT, stating, “The task ‘PointCloudStatsExtractor’ cannot be run. Reason: An Error occurred expanding environment variables in the path: “. Verify the Environment Variable is defined in the System Properties of this computer.” Probable Resolution: This error message likely indicates that the output dataset…
Problem: LP360 Errors when trying to run a PCT, stating, “Validating Settings Failed. (8716)”. Clicking on “Expand this” will provide additional insight such as Exception Information: HRESULT: 0x80004005 Description: Invalid dataset name. (8737) Probable Resolution: This error message likely indicates that the output dataset (shapefile) has not been specified, or it is relying on the…
Problem: In LP360 for ArcGIS, while trying to Define the 3D Window’s Extent, LP360 errors stating, “Getting Spatial References Failed (17124)”. Expanding the error message dialog for more information reveals, “QI to ISpatialReference failed (21422)”. Probable Resolution: The most probable cause is the lack of a Spatial Reference System (SRS) specified on the LAS Layer…
Problem: In LP360 for ArcGIS, while trying to Draw a Profile Line, LP360 errors stating, “Completing the construction of the profile line failed. (17020)”. Expanding the error message dialog for more information reveals, “QI to ISpatialReference failed (21422)”. Probable Resolution: The most probable cause is the lack of a Spatial Reference System (SRS) specified on…
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…
Reckon has been deprecated and replaced by LP360 Online, including the LP360 Portal and LP360 Cloud. Reckon is AirGon’s Amazon Web Services cloud hosted data management and delivery system. Service providers use Reckon to deliver content and volumetric results to their customers, whereas owner-operators use Reckon to directly manage their analytic results. Reckon provides multiple…
Symptoms: In ASPSuite, the ephemeris download fails. It just does nothing. Probable Resolution #1: Verify your machine has a proper internet connection and try again. Probable Resolution #2: Verify the ephemeris file is available. The broadcast ephemeris is available immediately, the ultra-rapid should be available within six hours of your flight. Probable Resolution #3: Manually…
Problem: In ASPSuite, processing the Interpolating Camera Events step results in an, “Error: Rover Position File (.pos) is Empty”. Probable Solution #1: The base station coordinate was entered incorrectly. Check the base station coordinate and be sure that southern latitudes and western longitudes have a negative sign. Note the base station must be entered in…
LP360 can be inefficient when working with very dense point clouds, such as Dense Image Matching, for ground classification if appropriate steps are not taken in the workflow. In fact, be aware that it simply crashes if you have to use a large seed size (e.g. 200 feet on some machines) that requires more points…
