Airbus Defence and Space released its global elevation model that was captured by the twin TerraSAR-X and TanDEM-X radar satellites in 2014 and now is producing Digital Terrain Models based on this dataset. The 12-meter-resolution pole-to-pole elevation data are a major improvement upon the commonly used 30-meter USGS SRTM data. Earth Imaging Journal spoke with Gertrud Riegler, WorldDEM Product Manager, Airbus Defence and Space, at the International Space Symposium about this new dataset and its many uses.
