GeoCue’s repository of articles covering tools, tips, and workflows for processing point clouds in LP360 Geospatial.
The new and improved contour smoothing algorithm removes noisy data which causes contour jaggedness by interpolating the Z elevation around contour levels, thereby smoothing the surface and creating much better contours. This display works for both the Map View and 3D view when the user has turned on this setting via the usual Smooth Contours…
The Basic Filter Point Cloud Task (PCT) allows you to define one or more point filters and assign the set of points matching the point filter to a classification. This PCT is useful for conducting simple reclassifications of point data in a LIDAR project. Reclassifying points from the old Model Keypoint class 8 to the…
It may seem that there is an edge mismatch between Digital Elevation Model(s) (DEM) created with LP360 that is showing up when the grids are viewed in different software platforms. For instance, a user might see an offset between grids such as in the example below: After further research into the matter it turns out the issue is…
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 volumetric computations. Automatic Toe Extraction with Overhead: You will note that the automatic toe extraction Point Cloud Task (LP360 Advanced…
Problem: When adding files to the map some of the LAS files won’t load and you are presented with the following messages about “Duplicate File IDs”. Caller’s Message: Adding layer to the map failed (22705) Exception Information HRESULT: 0x80004005 Description Duplicate file ids Caller’s Message: Exception Information: HRESULT: 0x0 Unable to retrieve extended COM error…
Problem: While adding LAS files to the ArcMap document using the LP360 for ArcGIS extension you receive an LP360 COM Exception, “Unable to create LPUtilities (22703)”. Caller’s Message: Unable to create LPUtilities (22703) Exception Information: HRESULT: 0x80040112 Unable to retrieve extended COM error information. Probable Resolution: The “Unable to create LPUtilities (22703)” error message generally…
Note: While the Arctoolbox tools are still an option within the product, the introduction of LAS File Analyst in v2018.1 and the ReProject/Shift LAS PCT in v2017.1, the new tools provide more efficient and robust tools and are now the recommended tools to use. Problem: When you try to run one of the LP360 Arctoolbox tools,…
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…
