Compute lidar metrics (vector)#

Algorithm ID: hedgetools:lidarfeaturemetrics

Compute a set of choosen lidar derivated metrics on each polygon of the given polygon layer from COPC point cloud files. COPC files are point clouds files optimized for spatial request and can be created from common LAS/LAZ files using QGIS pdal:createcopc algorithm. The full list of available metrics is given here.
