Airborne lidar data
WebLight detection and ranging (LiDAR) technology, which is an efficient way to collect three-dimensional point clouds over a large area, has been widely used to produce DTMs. To generate DTMs, ground and non-ground measurements have to be separated from the LiDAR point clouds, which is a filtering process.
