GeoCue’s repository of articles covering tools, tips, and workflows for processing point clouds in LP360 Geospatial.
When connect to a machine using RDP, adding a WMS backdrop to LP360 or True View EVO results in the message, “Drawing Map Complete” showing in the lower left-hand corner, but no image is displayed for the WMS layer. LP360 and True View EVO use OpenGL and Microsoft’s Remote Desktop only uses software OpenGL by…
A common practice amongst GeoCue customers (and internally) is to use previously established control points to compare with an sUAS produced point cloud to gather absolute accuracy statistics. The vertical mean error from these statistics is often used to “Debias” a dataset. This is simply shifting the point cloud data to match the measured control…
The Proximity Classifier Point Cloud Task found in LP360 and True View EVO classifies points based on attributes of a proximal point. A couple of use case scenarios could be: Classifying a new dataset based on an older one for datasets from multiple collect times. Classifying a subset of a larger dataset, then incorporating the…
The Height Filter point cloud task is used to classify points that are a vertical distance to a defined surface such as ground. This filter can be useful for classifying points into vertical strata from ground which can then be used in density studies. The Height filter can also be used to locate points that…
Attempting to modify any project setting in LP360 or True View EVO results in an error stating, “Invalid value for flush interval. Must be a valid positive number.” Upgrade to v2020.2.33.3 or later to avoid encountering this error. This was a bug we introduced when we introduced the new diagnostics logging tab in the v2020.2.33.0…
Problem: When using the LP360 for ArcMap extension, the user cannot display features in the profile or 3D view. Probable Solution #1: Verify the spatial reference system (SRS), both horizontal and vertical, defined for the shapefile feature are correct and complete in reference to the point cloud. In order to display the feature properly, the…
User attempts to add WMS basemap and receives the error message, “Draw Failed: Interface not supported (9934)”. Despite projection being set for the project and nothing blocking the basemap download (firewall, anti-virus, etc.), the user is unable to display a basemap. Probable Resolution #1: User is currently in an RDP session. Solution is to: “Configure…
Attempting to display Breakline enforcement using the “Use Breakline Enforcement” button, but the map display does not reflect using breaklines to alter the TIN surface display, and the user is unable to display breakline enforcement despite verify the settings and breakline geometry. Probable Solution #1: Use the “creating feature from existing feature” option from the…
In LP360 for ArcMap, when attempting to use the Reproject PCT containing a target spatial reference system (SRS) with the vertical defined, the user encounters the message, “Error setting up the transformation: A target vertical coordinate system was specified, but the source vertical coordinate system was not.” ArcMap does not handle SRS with a vertical…
In the LP360 LAS files tab, there are various symbols that represent different states of LAS files loaded. Please reference the list below for information regarding what these symbols represent: : Pyramid File Created : Pyramid File Not Created : Pyramid File Out-Of-Date : LAS File Not Loaded : LAS File Loaded : Opened For…
