315 articles LP360 Geospatial Tools, Tips and Workflows

GeoCue’s repository of articles covering tools, tips, and workflows for processing point clouds in LP360 Geospatial.

LP360 Tool Guides

There are many tools and keyboard shortcuts that exist within the LP360 product suite, including LP360 for ArcGIS, LP360 Geospatial, LP360 for sUAS, TrueView EVO/LP360 Drone. Remembering all of them and where to find them may prove difficult, particularly for beginner or casual users. To help we’ve created tool guides that provide the names of…

Point Cloud Tasks

What is a Point Cloud Task (PCT)? A function (Extract ground, Conflate Line) that operates on points, rasters, and/or vectors. A task can be a filter and/or an extractor. A filter classifies or changes the classification values for points (e.g. classify ground). An extractor extracts information from the point cloud data into vector, image or…

Creating dz Images

Relative vertical accuracy, or flight line offsets, or the swath-to-swath fit between flight lines or drive passes can be qualitatively assessed using dz images. Or quantitatively assessed by exporting and analyzing the values. The USGS LiDAR Base Specification has evolved over the years with some different recommendations for evaluating interswath (overlap) consistency, and there are…

Error Updating Project Catalog

Attempting to save an LP360 project results in “An error occurred updating the Project Catalog with Project:”, followed by “Detail: Error: Unable to open Projects File. Project not added to list. C:\ProgramData\LP360\PMProjects.json”. The global projects file, “C:\ProgramData\LP360\PMProjects.json”, used by the LP360 Project Manager was created with administrator permissions when LP360 or TrueView EVO first launched…

Building Filter and Extraction for dense datasets

Some LP360 Point Cloud Tasks (PCT’s) were originally designed for older manned lidar datasets, which have significantly lower point density than modern sUAS datasets. TrueView and other sUAS sensors have the capability of producing much denser point clouds, so these processes can take much longer if running on the entire dataset. A common strategy and workflow…

Classify by Statistics – Quartile classification settings

Classify by Elevation Quartiles In the Classify by Statistics PCT, the user can set the output of outliers and quartile classification using the standard output class/flag dialog. A little info regarding quartiles: https://byjus.com/maths/quartiles/. The section applicable to Quartile classification is shown in Figure 1: This classifier works as follows: The area to be processed (as determined…

Your project size now exceeds 4 km² or 10 km²

The LP360 sUAS license level limits the project size to 4 km². The LP360 EVO, EVO 3DIS, and LP360 Drone license levels limit the project size to 10 km². If LP360 determines the project size exceeds this limitation, this informational dialog, “Your project size now exceeds 4 km², causing sUAS to enter LP360 Viewer mode”…

Image Explorer Drive Method Setting

The Image Explorer Drive Method determines the method used to sort matching imagery. Range will sort images by shortest distance from the camera position XYZ to the projected XYZ. Photo Center will sort images by the shortest distance from the photo center to the projected raster column and row. GPS Time will sort images by…

Reformatting and tiling orthomosaic rasters

When generating a GeoTIFF orthomosaic raster using Metashape or importing a large ortho from third party software into LP360 or TrueView Evo, the initial file is written in BigTIFF format which is incompatible with some CAD software packages, including Civil3D. There are also size considerations to be factored in as some orthos can be dozens…

BigTIFF file conversion for CAD package import

When generating a GeoTIFF Ortho using Metashape through TrueView Evo, the initial file is written in BigTIFF format which is incompatible with some CAD software packages, including Civil3D. There are also size considerations to be factored in as orthos that are generated in TIFF format are subject to the 32-bit size limit of 4GB. This…
