Abstract

The German TanDEM-X mission produced a new DEM with unprecedented accuracy. From December 2010 to March 2015 the two X-band radar satellites TerraSAR-X and TanDEM-X have been operated in close formation as a single-pass SAR interferometer. The data acquired in bistatic mode were processed to yield a global DEM with an independent pixel spacing of 12 m and an absolute height error of < 10 m. We used this DEM to generate a TanDEM-X sample of more than 120 confirmed impact structures, all mapped with high spatial resolution. We present the status of the TanDEM-X DEM, show how our TanDEM-X impact results compare with those derived from other existing digital elevation models and illustrate results of our global mapping project.
