摘要：
A detailed assessment of the accuracy of the TanDEM-X derived WorldDEM digital elevation models with reference to airborne lidar data was performed for a quarter degree tile located to the west of Rapid City, SD, USA. In addition to assessing the accuracy under standard conditions (uniform unvegetated terrain) analyses on the effects of vegetation height and terrain slope were conducted. Results for standard conditions and even in unvegetated terrain with slopes ranging from 0 degrees to 80 degrees are in agreement with the TanDEM-X accuracy specifications. The accuracy of canopy height (canopy heights <= 25 meters) degrades by a factor of at least 1.4 with respect to the bare terrain which is expected because the radar energy propagates through the vegetation canopy before scattering back to the sensor.
