DTM Digital Terrain Model is a digital elevation model in which terrain data has been further enhanced
with breaklines, creating greater accuracy as it contains additional information defining terrain in areas where Lidar data alone is unable to do the job effectively.
Terrain models are based on point clouds obtained during airborne laser scanning. A Digital Terrain Model (DTM) is a true representation of the terrain relief. When we supplement it with extra information about objects on the surface, we can create a Digital Surface Model (DSM). Being a universal tool, terrain models can be used for determining slope and elevation, but also for identification of landforms and discovery or inventory of archaeological objects.
Feiyan Technology also generates fully detailed DTM Digital Terrain Model for contour generation, orthophoto rectification, and flood plain mapping.
