BEV Data topic Height

The digital terrain height model (DGM) DTM) describes the earth's surface (natural soil, without vegetation) in the form of point quantities arranged in a regular grid and georeferenced in position and height. The high-resolution ALS-DGM data was collected using Airborne Laser Scanning technologies and is a cooperation product of the Austrian governmental spatial data providers of the federal and state governments. The Digital Surface Model (DOM) DSM) describes the earth's surface and all objects on it in the form of point quantities arranged in a regular grid and georeferenced in position and height. In contrast to the digital terrain model (DGM), the vegetation and building surface is thus shown. The high-resolution ALS-DGM data was collected using Airborne Laser Scanning technologies and is a cooperation product of the Austrian governmental spatial data providers of the federal and state governments.
