DEM over Europe from the GMES RDA project (EU-DEM, resolution 25m) - version 1, Oct. 2013

The Digital Elevation Model over Europe from the GMES RDA project (EU-DEM) is a Digital Surface Model (DSM) representing the first surface as illuminated by the sensors. EU-DEM covers the EEA39 countries and it has been produced by a consortium led by Indra. Intermap edited the EUDEM and AGI provided the water mask. The EU-DEM is a 3D raster dataset with elevations captured at 1 arc second postings (2.78E-4 degrees) or about every 30 metre. It is a hybrid product based on SRTM and ASTER GDEM data fused by a weighted averaging approach. The EU-DEM is generated as a contiguous dataset divided into 1 degree by 1 degree tiles corresponding to the SRTM naming convention. These tiles have then been aggregated into 5°x5° tiles which have been projected to ETRS89-LAEA by JRC. The resulting tiles (1000x1000km) are made available as well as a mosaic of them.

The vertical unit of this DSM is metre.

The tiles are provided as GeoTIFF with LZW compression.

The mosaic is provided as GeoTIFF with DEFLATE compression.

Ownership of EU-DEM belongs to European Commission, DG Enterprise and Industry.

Explanation: See the referenced specification

Statement: The EU-DEM data product 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 product is edited to ensure that water features are adequately represented and consistent with the hydrography layer provided by Aerogeodezijos Institutas (AGI) in Kaunas, Lithuania. 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 hydrographic features and pits and bumps. In areas above 60 degress North, the EU-DEM generation process is supported by other DEM data sources provided by JRC. Water features are flattened (oceans, lakes) and stepped (rivers) based on the hydrography data produced by AGI. The spatial reference system is geographic, lat/lon with horizontal datum ETRS89, ellipsoid GRS80 and vertical datum EVRS2000 with geoid EGG08.
