本贡献介绍了 TanDEM-X 派生的数字表面模型 (DSM) 与高分辨率机载激光雷达数字地形模型 (DTM) 之间的比较结果，该模型针对德国以农业区和森林为特征的流域。它为 TanDEM-X 数据的整体高质量提供了证据，并为无法获得高分辨率和高质量数据的区域中 TanDEM-X 衍生的 DSM 的不确定性评估提供了指南。
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.
