Page Summary
-
The Copernicus DEM is a Digital Surface Model (DSM) representing the Earth's surface, including buildings, infrastructure, and vegetation.
-
This DEM is derived from an edited DSM called WorldDEM™, incorporating features like flattened water bodies and consistent river flow.
-
The dataset is available from December 2010 to January 2015 with a pixel size of 30 meters.
-
The GLO-30 dataset has a free worldwide license, excluding Armenia and Azerbaijan.

Description
The Copernicus DEM is a Digital Surface Model (DSM) which represents the surface of the Earth including buildings, infrastructure and vegetation. This DEM is derived from an edited DSM named WorldDEM&trade, i.e. flattening of water bodies and consistent flow of rivers has been included. Editing of shore- and coastlines, special features such as airports and implausible terrain structures has also been applied.
The WorldDEM product is based on the radar satellite data acquired during the TanDEM-X Mission, which is funded by a Public Private Partnership between the German State, represented by the German Aerospace Centre (DLR) and Airbus Defence and Space. More details are available in the dataset documentation .
Earth Engine asset has been ingested from the DGED files.
