Digital Terrain Models for Germany

Details with grid width 10 m

Digital Terrain Model
with grid width 10 m (DGM10)

Grid width:
10 m (in Gauß-Krüger projection)

Height data:
referenced to mean sea level (NN )

Source:
Acquisition of the height data by the "Landesvermessungsämter" (state surveying offices) through different methods: Laserscanning, photogrammetry and digitisation of contours. Adoption and format conversion of the data by BKG as well as fusion of the datasets into one consistent terrain model.

Accuracy:
Position: ±0,5 - 3 m, absolute height: ±0,5 - 2 m

Details with grid width 25 m

Digital Terrain Model
with grid width 25 m (DGM25)

Grid width:
25 m (in Gauß-Krüger projection)

Height data:
referenced to mean sea level (NN )

Source:
Acquisition of the height data by the "Landesvermessungsämter" (state surveying offices) through different methods: Laserscanning, photogrammetry and digitisation of contours. Adoption and format conversion of the data by BKG as well as fusion of the datasets into one consistent terrain model.

Accuracy:
Position: ±1 - 3 m, absolute height: ±1 - 3 m
