1 ARC SECOND DIGITAL ELEVATION DATA


New 1" Digital Terrain Data for Europe were added and existing areas were updated on 15 May 2022. These data are based on ground level sources and are not affected by tops of trees or buildings. They include full, continuous coverage of the Alps and Pyrenees.

The data were extracted from the following freely available National Elevation Dataset and other sources:
Norway, Finland, Denmark 10m NED
Sweden 50m NED
Russia (north west) 100K topos

England and Wales about 70% from 2m Lidar data, remainder from 25K topos
Scotland 25K topos
Ireland 10m NED in north, 50K topos in south

France, Spain 5m LiDAR NED; some input from 25K topos in border areas. Portugal not covered
Germany SH, Niedersachsen, Hessen, BW, MP - 25K topos; Bavaria 50K DEM, RLP and Thuringia 25K DEM; hi-res LiDAR elsewhere
Italy Piemonte, Aosta, Lombardia, Veneto, Friuli, Liguria, 5m or better provincial; 10m TinItaly elsewhere
Austria 10m NED
Switzerland mostly 2m canton data but some input from 10K and 25K topos

Czechia 10K topos, incomplete coverage
Poland, Slovenia, Netherlands, Belgium, Luxembourg 1m LIDAR NED (numerous small voids in NL)
Slovakia 10m NED
