Abstract

The main product of the TanDEM-X mission is a global interferometric digital elevation model (DEM) that is finally calibrated due to residual systematic offsets and tilts. For the final DEM product single acquisitions (so-called data takes) are calibrated and merged to tiles of a size of 1°x1°. Finally the globe will mostly be covered with two acquisitions. The quality of the calibration of the data takes and also the accuracy of the final DEM highly depends on the terrain and the vegetation. Therefore, three different test areas where we have to deal with good, medium and difficult terrain conditions will be presented here.
