GeoCue’s repository of articles covering tools, tips, and workflows for processing point clouds in LP360 Geospatial.
LP360 now has a full set of feature analysis and editing tools for working with the geometries of features – points, lines and polygons – in your project[1]. As often happens with LP360 features, the initial driver for adding this capability was a very specific problem; editing the toes of stockpiles being used in volume…
In the LP360 Add Files dialog there is a Compatibility Group column in the Advanced Columns that can be used to help understand why the LAS data file will be placed on the specified target Map Layer. The letter assigned in this column to each file contain some insight into which LAS files can go on…
At times while working with GeoCue Group Support it may become necessary to exchange large files or large numbers of files. We suggest the use of an FTP Client to make this easier. If you don’t have your own, or are not familiar with using an FTP client we suggest using the FileZilla project. FileZilla…
Problem: Adding LAS files to the LP360 Add Files dialog results in an error stating, “Error updating columns (13498)”. Probable Resolution: Something is missing from the header of the LAS file that is supposed to be there according to the file and the LAS specification. Most usually seen when the WKT flag is toggled, but…
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…
