The points of the “raw” LIDAR data include elevations for the ground, buildings, highway overpasses, forest canopy, and anything else that the laser beam encountered. In data processing, each of these points is classified into one of the LAS classification values. In addition, the LiDAR data is organized into the PAMAP tile structure.
