Abstract :
This contribution presents the results of a comparison between a TanDEM-X derived Digital Surface Model (DSM) and a high resolution, airborne LIDAR-based Digital Terrain Model (DTM) for a catchment characterized by agricultural areas and forest in Germany. It provides evidence for the overall high quality of the TanDEM-X data and guidelines for uncertainty assessment of TanDEM-X derived DSM in areas where high resolution and high quality data is not available.
