WorldDEM is a Digital Surface Model that 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. For more information, please refer to the WorldDEM Technical Product Specification.
The geographic coverage is global.
