EU-DEM is an elevation dataset covering Europe at a 25 metre resolution.
The dataset was created by merging elevation data from the SRTM and ASTER global datasets, as well as from Soviet topo maps at high latitudes. The datum used is EVRS2000.
The dataset covers European Environment Agency member states, plus some countries to the east. Coverage extends to small parts of Northern Africa. Unlike SRTM, EU-DEM includes the Scandinavian regions north of 60°.

The stated vertical accuracy is ± 7m RMSE. Differences to SRTM and ASTER typically fall within this 7m range even with the datasets using slightly different vertical datums. Elevations for Lake Geneva, Switzerland are 370m, 374m, and 372m for SRTM, ASTER, and EU-DEM respectively.
NODATA values for elevations over seas and oceans, where both ASTER and SRTM assign these areas an elevation of 0m. This means that Open Topo Data isn't able to interpolate elevations for locations very close to the coast and will return a value of
NaN in places where SRTM and ASTER might return a 0m or 1m elevation.
The advantage of the
NODATA oceans is that you cane use EU-DEM without clipping to a coastline shapefile.
Adding EU-DEM to Open Topo Data
As of Jan 2024, EU-DEM is no longer available to download via copernicus.eu.
Download and unzip the folder into:
Then create a
Finally, rebuild to enable the new dataset at localhost:5000/v1/eudem25m?locations=51.575,-3.220.
If you don't have gdal installed, you can use the tiles directly. There are instructions for this here, but because the EU-DEM tiles don't come with an overlap you will get a
null elevation at locations within 0.5 pixels of tile edges.
The Open Topo Data public API lets you query EU-DEM for free:
