GeoCue’s repository of articles covering tools, tips, and workflows for processing point clouds in LP360 Geospatial.
Feature Analyst is an exciting new tool that will appear in LP360/Topolyst 2016.2. To motivate this discussion, I will provide a synopsis of a few use cases for Feature Analyst here. A detailed look at these cases is presented at the end of this article. Examples of tests you will be able to perform with…
LP360 includes a Point Cloud Task (PCT) that will automatically digitize the toe of a clean stockpile and can allow for the classification of overhead structures such as conveyors. This tool saves considerable time when computing stockpile volumetrics. A “clean” stockpile is one with a clear demarcation of the boundary from a 3D perspective that…
If you’re i/o bound, which is usually the case with LIDAR or photogrammetric point cloud processing, you need to figure out what kind of i/o you’re doing at the bottleneck. Case 1: If you’re just waiting for a single tile to load, your slowdown may be from low RPM HDD, but more likely you’re hitting…
Point data can be exported into Bentley’s MicroStation design file format using the LP360 Export Wizard. LP360 uses a seed design file as the basis to create the new design file with the points in it. Hence, the working units of the seed file affect the generated point DGN file. The seed file used by…
Symptom: Receive an error message, “Error Writing Global Parameter Sets File (14761): Apply Rail Extractor Parameter Set Error(14759)” while trying to save the advanced Rail Parameters Point Cloud Task. Probable Resolution: This error message generally occurs when one of the specified parameters is not valid. Verify the entered values to continue.
WMS (Web Map Service) is an OGC (Open Geospatial Consortium) standard which is widely supported: http://www.opengeospatial.org/standards/wms WMS layers can be added into LP360 for ArcGIS, LP360, Mission Planner, LIDAR Server and Reckon. LP360 for ArcGIS, LP360 and Mission Planner all display WMS data as a layer. These different programs provide users the ability to display…
The Downstream Constraint method is used to create 3D polylines that are guaranteed to flow in the downhill direction. This method is useful for creating breaklines that hydrologically enforce streams in a downhill direction. The first step in the conflation method is to perform a drape of the geometry to the LIDAR surface. The drape…
Problem: ArcGIS crashes every time I load an LAS file. Probable Resolutions: Please submit the ESRI Crash Dump report to support@LP360.com so that we may investigate further. Try loading the LAS file(s) a second time. If that doesn’t work then the QVR files may have become corrupt. Delete and regenerate them. Try loading a file…
Symptom: When adding LAS files to LP360 a message appears in the message column of the Add Files dialog stating, “Unable to open the LAS file (17657)” Probable Resolution: Verify that the LAS file is not open in another program or by another process. Verify that you have read permissions, or read/write depending on the…
Problem: Receive an LP360 COM Exception attempting to open files for read/write. Caller’s Message: Failed to open the file for read/write. The file ‘D:\Client_Data\sample.las’ cannot be edited. (18309) Exception Information: HRESULT: 0x0 Unable to retrieve extended COM error information. Probable Resolution: Verify that the files are not open for read in another session or program.…
