Copernicus DEM GLO-30: Global 30m Digital Elevation Model

    • 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™, 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 .

    The DSM uses the EGM2008 vertical datum: EPSG:3855 . This means a 0 elevation at a location does not imply the location is at a mean sea level.

    Earth Engine asset has been ingested from the DGED files.
