GeoCue’s repository of articles covering tools, tips, and workflows for processing point clouds in LP360 Geospatial.
If your organization has strict security settings, some of the executables installed and used by LP360 or True View EVO could get blocked and prevent LP360/EVO from operating correctly. It may be necessary to get your IT department to add these executables to an approved list. The following instructions will show you how to find…
Multipart features are not supported for the Feature Edit tools in LP360 standalone and may result in an error message such as, “…Complex polygons is not supported”. The polygon must be a single part feature. This can be verified in the Feature Analyst dialog: You will need to first Disassemble Multipart Feature, then run the Split Geometry,…
Contours can be generated from a TIN surface at specified intervals. The contours are saved to one of the three following file formats: shapefiles, DXF, or DGN. Contours are stored as 3D polylines for DXF and DGN file formats. You have a choice to save polylines as 3D or 2D when exporting to shapefiles, where…
LP360 has several very useful command line executable utilities that can be used to simplify different tasks or improve the efficiency of large batch processes when working with substantial amounts of data or repeating processes. LDExport was added to this utility catalog with 2017.1. It simplifies the export of LAS points and surfaces, for example…
This post applies if your grid to ground conversion requires needing to apply a horizontal rotation about an origin point and is defined by: Horizontal Translation North (tN) Horizontal Translation East (tE) Horizontal Rotation (Rz) Horizontal Origin Northing (N0) Horizontal Origin Easting (E0) Horizontal Scale Factor Then, if the horizontal scale factor is one, luckily,…
This post applies if your grid to ground conversion requires applying a horizontal scale about an origin point and is defined by: Horizontal Origin Northing (N0) Horizontal Origin Easting (E0) Horizontal Scale Factor Scale based grid to ground transformations are probably the most common. If the origin point is not defined, it is usually implied…
The Create Seawall Feature tool, found on the LP360 feature edit toolbar, allows the user to create a contiguous polygon feature at the proper width/depth and height of a seawall (or any similar feature) contained in the point cloud. This function can be scaled to fit the specific scenario of the user: from simple walls…
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…
