The geomorphological map of Denmark at a scale of 1:200,000 was produced through systematic mapping and interpretation of landforms. Landform types were interpreted using topographic maps, geological maps and the national digital elevation model of Denmark. Previously published geomorphological maps, landscape descriptions and interpretations from available literature were also incorporated.

The mapping was carried out manually based on an integrated geomorphological assessment of landforms, surface structures and spatial relationships. The map represents a synthesis of geomorphological units generalised to the scale of 1:200,000, and the classification of landforms follows the methodological framework defined for the project.

In version 3, the entire country has been mapped, although terrain striping is not fully mapped in Jutland north of Horsens. Zealand and the islands were mapped in 2013 and revised in 2018, Southern Jutland and Funen were mapped in 2018, and northern Jutland was mapped in 2022. The map reflects the geomorphological understanding at the time of publication.
