Description
The digital surface model (DOM) contains high-precision height data for the earth's surface (dot grid with resolution 0.5m) including vegetation and buildings. The data was collected using the Airborne Laser Scanning (LiDAR) method. The LiDAR aerial flight of 25.07.2014 took place during the leafy growing season (which favoured a very strong reflection of the laser beams in the wooded areas), while the LiDAR aerial flight of 05.04.2014 took place during the unleavened growing season. For this reason, the derived DOM of 25.07.2014 depicts the surface (earth surface with vegetation and buildings) better than the DOM of the LiDAR aerial flight of 05.04.2014.
