King George Island TanDEM-X DEM, link to GeoTIFF

We have generated a new digital elevation model for entire King George Island, Antarctica, using summer TanDEM-X bistatic SAR satellite data. The data was processed using differential SAR interferometry with an older DEM as reference. 4 TanDEM-X scenes from January 2012 were used as input. The new DEM was referenced to and validated against DGPS measurements. Height values are given in reference to ellipsoid (WGS84).
