LIDAR_COMPARE

The LIDAR_COMPARE command supports the functionality of the Lidar QC tool and the Find Duplicate Lidar tool. This allows for comparing the elevations from loaded Lidar point clouds to loaded 3D control points. You can also adjust the Lidar points to match the control points. This command also supports deletion of duplicate points. The following parameters are supported by the command:

SAMPLE

This script will compare and adjust loaded lidar to loaded vector point features, and generate a comparison report in the same folder as the script:

LIDAR_COMPARE REPORT_FILENAME="%SCRIPT_FOLDER%report.csv" FIT_POINTS=YES

An example script to delete duplicates with the same XYZ location, intensity, and GPS time looks like:

LIDAR_COMPARE DELETE_DUPLICATES=YES DUPLICATE_ATTR="INTENSITY" DUPLICATE_ATTR="GPS_TIME"
