Welcome to the EOC Geoservice

The TanDEM-X PolarDEM 90m of Antarctica is a gap-free and edited version of the TanDEM-X digital elevation model (DEM) provided in Antarctic Polar Stereographic projection (EPSG:3031) with a pixel spacing of 90 meters. The editing process comprises a smoothing of noisy areas, a gap-filling with new TanDEM-X acquisitions and a replacement of frozen and partially open sea-ice areas with geoidal undulations. The majority of the data were acquired between April 2013 to September 2014. The TanDEM-X PolarDEM is a project developed by the German Remote Sensing Data Center (DFD) at the German Aerospace Center (DLR) within the activities of the TanDEM-X mission. It is a framework for the provision of derivatives of the global Digital Elevation Model (DEM) of the TanDEM-X mission for Polar Regions [1]. The dataset can be visualized in the EOC Geoservice Webapp [2] and after registration, also be downloaded from the EOC Download Service [3].
