Digital Elevation Models (DEM) represent fundamental data for a wide range of Earth surface process studies. Over the past yearsthe German TanDEM-X mission acquired data for a new, truly global Digital Elevation Model with unpreceded geometricresolution, precision and accuracy. First processed data sets (i. e. IDEM) with a geometric resolution of 0.4 to 3 arcsec have beenmade available for scientific purposes. This includes four 1° x 1° tiles covering the Kruger National Park in South Africa. Here wedocument the results of a local scale IDEM validation exercise utilizing RTK-GNSS-based ground survey points from a dried outreservoir basin and its vicinity characterized by pristine open Savanna vegetation. Selected precursor data sets (SRTM1, SRTM90,ASTER-GDEM2) were included in the analysis and highlight the immense progress in satellite-based Earth surface surveying overthe past two decades. Surprisingly, the high precision and accuracy of the IDEM data sets have only little impact on the delineationof watersheds and the calculation of catchment size. But, when it comes to the derivation of topographic catchment properties (e.g.mean slope, etc.) the high resolution of the IDEM04 is of crucial importance, if - from a geomorphologist’s view - it was not for thedisturbing vegetation
