European Digital Elevation Model (EU-DEM), version 1.0

Abstract

EU-DEM v1.0 is a digital surface model (DSM) representing the first surface as illuminated by the sensors. It is a hybrid product based on SRTM and ASTER GDEM data fused by a weighted averaging approach and generated as a contiguous dataset divided into 1 degree by 1 degree tiles, corresponding to the SRTM naming convention. The spatial reference system is geographic, lat/lon with horizontal datum ETRS89, ellipsoid GRS80 and vertical datum EVRS2000 with geoid EGG08. These tiles have then been aggregated into 5°x5° tiles which have been projected to ETRS-LAEA by the Joint Research Centre (JRC) of the European Commission.
The implementation of EU-DEM v1.0 was coordinated by the European Commission in 2009-2011 in the framework of the Reference Data Access (RDA) Action of the EU GMES/Copernicus programme.

Lineage

The EU-DEM v1.0 is derived from an automated data fusion process using SRTM and ASTER GDEM digital surface model (DSM) data. Intermap's NEXTMap Europe dataset is utilized to remove any consistent horizontal bias in the GDEM data. The EU-DEM v1.0 is edited to ensure that water features are adequately represented and consistent with the hydrography layer. Residual clouds within the GDEM data are identified and removed same as suspect data extremely differing from the SRTM data. All EU-DEM tiles are edited interactively in a 3D stereo environment. The editing is restricted to the hydrographical features and pits and bumps. In areas above 60 degrees North, the EU-DEM generation process is supported by other DEM data sources provided by the JRC. Water features are flattened (oceans, lakes) and stepped (rivers) based on the hydrography data. The spatial reference system is geographic, lat/lon with horizontal datum ETRS89, ellipsoid GRS80 and vertical datum EVRS2000 with geoid EGG08.

Access and use conditions

Access to data is based on a principle of full, open and free access as established by the Copernicus data and information policy Regulation (EU) No 1159/2013 of 12 July 2013. This regulation establishes registration and licensing conditions for GMES/Copernicus users and can be found. Free, full and open access to this data set is made on the conditions that: 1. When distributing or communicating Copernicus dedicated data and Copernicus service information to the public, users shall inform the public of the source of that data and information. 2. Users shall make sure not to convey the impression to the public that the user's activities are officially endorsed by the Union. 3. Where that data or information has been adapted or modified, the user shall clearly state this. 4. The data remain the sole property of the European Union. Any information and data produced in the framework of the action shall be the sole property of the European Union. Any communication and publication by the beneficiary shall acknowledge that the data were produced “with funding by the European Union”.
