Module of DSM2DTM

Providing a raster-form 2.5D DSM, the module is to transform DSM to DTM (Digital Terrain Model) automatically, i.e., removing the height of building and tree, only remaining the height of pure ground. The algorithm can select different level of terrain details in the light of the requirements. The DSM transformed to DTM can be extracted from satellite image, aerial image, UAV image as well as LiDAR points.
