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.
To reproject a raster in LP360/TrueView Evo you will need to establish the source SRS if one does not already exist. Do this by right-clicking on the raster layer, selecting Properties, SRS tab, and the ellipsis in the top right of the dialog. The Select Coordinate System dialog will pop up where you can setup…
This page is no longer updated. Please visit the updated page on the new LP360 Support Knowledge Base for the latest information. Import Cycle into True View EVO results in the error, “Error Creating trajectory Points SHP File: <path>\Positions\Area_TrajectoryPoints_CYYMMDD-HHMMSS_FYYMMDD_HHMMSS.shp. Error creating Trajectory Point Shapefile”. The full path, including file name and extension, is too long.…
LP360 has many tools for analyzing stockpiles and terrain. With these tools, it is possible to calculate average stockpile height and quantify this on a pile by pile basis in an automated fashion. The Volumetric Analysis point cloud task (PCT) has the ability to calculate a height dataset when the base and hull is known.…
Executing the Reproject LAS Point Cloud Task encounters the error, “Error setting up the transformation: Missing geoid file for source vertical coordinate system.” The spatial reference system (SRS) must be properly set on the LAS Layer as that is where the Reproject PCT will be looking for the information. For example, if the original LAS…
A common issue that is encountered when trying to take a bare earth surface generated from LIDAR or photogrammetric point cloud datasets into other programs is that those other programs cannot handle the volume of data. LP360 currently provides four options that can be used to thin the bare earth dataset to allow you to…
Starting the Create True View Trajectory process results in a Trajectory File Time Range Warning, “Warning: The Post Process Trajectory File start time was AFTER the start time of the first flight line. Geocoded LIDAR may not cover all of your flight lines. Continue and create all possible Trajectory Files?” This check was put in…
Attempting to run POSPacCloud to process the trajectory solution for a TrueView 3DIS results in an error message stating, “POSITION_FILE_PARSE_FAILED”. Verify the project path contains no special characters as the Applanix POSPacCloud utility cannot handle them. If you do have special characters, close TrueView EVO, take the special characters out of the path, then re-open…
The following is a brief explanation for how to set filters for classification flags in LP360. The Live View Filter allows the user to set flags for: single class, multiple classes, single flag, or multiple flag combination scenarios. For this example, we will review setting the Live View filter for displaying these flags. The same…
Canopy Height Model (CHM) is important for a variety of uses. The distinguishing factor of this model is that it is a height above ground model and does not represent absolute elevation. We can produce this model in LP360 with the following workflow that incorporates Point Cloud Tasks (PCTs) and the export function. Note: the…
In Feature Analyst, the Flat Feature analysis function allows the user to test that the delta Z (MaxZ – MinZ) for all vertices of a feature is less than the specified Z tolerance range. By default the value is 0, but the user can specify the tolerance value when activating this function in the Feature…
