GeoCue’s repository of articles covering tools, tips, and workflows for processing point clouds in LP360 Geospatial.
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…
LP360 Drone has a wealth of tools and workflows for point classification and exploitation. Below is a simple streamlined guideline for producing a ground surface. With a ground surface, the user can: better differentiate/classify vegetation, create contours, create a bare surface model for importing into CAD software, etc. This is accomplished by running a series…
The user in unable to edit LAS points in LP360 or True View EVO and receives the following error message: “Filters require editable points. Open the LAS files for read/write and try again.” Note: Read/write functionality applies to all True View Evo users. Also, applicable to all Standard and above LP360 license level users. For…
Unable to edit the project point cloud data that has been loaded into LP360. Functions (such as classification) won’t work properly. The user receives the following error message: “Filters require editable points. Open the LAS files for read/write and try again.” Note: The editing ability is available at the Standard, Advanced, or True Veiw Evo…
Originally posted on the GeoCue Group website on May 28, 2020 What causes “Noise”? Drone LIDAR systems that use “automotive grade” laser scanners are known to be “noisy” as compared to a high end survey grade LIDAR such as those from Riegl. Part of this noise phenomenon is an illusion caused by close point spacing (Nominal…
The user attempts to use the import DEM to LAS function in LP360 and receives the error message: “Failed to convert DEM Image file to LAS file: Error occurred converting DEM File: <filename>.<flt> to LAS File: <filename>.las” The error message is preventing the user from importing an extremely large DEM file and converting to LAS…
Profile Box/Profile Centerline are not visible in LP360 Map View. Only able to see where you are drawing the profile as you draw it. Once you’ve finished, it vanishes. The LP360 Viewer Integration toolbar has a button called “Draw the Profile Box in 2D View”. This needs to be enabled in order to see the…
Starting LP360 or True View EVO results in “LoadLibrary failed with error 87. The parameter is incorrect.” error. This indicates a graphics card driver issue. Several fixes include either renaming an ATI driver dll, rolling back the display driver to an older version, or replacing the video card with an NVIDIA one. This error may…
When attempting to convert point coordinates from one horizontal projection to another using LP360 or True View EVO, the user may see a warning message with the heading: “Datum Transform Warning!” if the datums of the projections differ or appear to differ based on their WKT. Before attempting to perform any coordinate system transformation/reprojection, it…
