WorldDEM Full Resolution


Provides access to a worldwide, consistent, and high precision Digital Surface Model at 12 m resolution in GeoTIFF format. It is derived from the TerraSAR-X and TanDEM-X satellites. The data acquisition started in January 2011 and was completed by mid-2015. WorldDEM represents the surface of Earth including buildings, infrastructure and vegetation. This dataset includes hydrological corrections, i.e. flattened water bodies and consistent flow of rivers, as well as shore- and coastline editing.
