The Geomorphological Map of Denmark, version 3 (2022), depicts landscape types across Denmark at a scale of 1:200.000. The landscape types are defined based on shared geomorphological characteristics that can be related to the processes responsible for their formation. Most landscape types were formed during Quaternary glaciations and by meltwater from the glaciers, while the map also includes post-glacial landscapes such as marine and coastal environments, river valleys, lakes and wetlands, as well as aeolian landforms. The map further reflects landscape features influenced by pre-Quaternary bedrock, including exposed crystalline basement on Bornholm and chalk formations in northern Jutland, as well as surface features related to subsurface structural movements. Anthropogenic landscapes resulting from land reclamation, drainage, excavation, and infilling are also represented. The map is based on systematic geomorphological mapping and interpretation of landforms derived from geological data, terrain analysis and existing cartographic material.

The MARTA database contains shallow seismic and acoustic data, information and geological samples. MATRA shows the distribution of marine sand and gravel resources and gives access to reports on raw material surveys. MARTA shows the distribution of marine sand and gravel resources and gives access to reports on raw material surveys. Data has primarily been acquired by GEUS and our partners., MARTA is the official Danish marine raw material database for data reported in accordance with the Danish Raw Material Act. MARTA is used by the raw materials industry and authorities and as a planning tool in connection with raw material extraction and marine construction projects including beach nourishment.

The Geological Map of Greenland at scale 1:2.500.000 provides a comprehensive regional synthesis of the geological evolution of Greenland from the earliest Archaean to the Quaternary. The map presents an integrated overview of Greenland’s geological framework, including Precambrian crystalline basement provinces, major orogenic belts, Phanerozoic sedimentary basins and widespread volcanic provinces. Greenland is characterised by large exposures of continental crust dominated by Archaean and early Proterozoic shield rocks that stabilised as part of the Laurentian shield. Younger geological elements are mainly developed along the margins of the shield, where sedimentation, deformation and magmatic activity reflect successive tectonic regimes through time. The map illustrates the distribution and relationships of these geological units and highlights the structural and stratigraphic architecture of Greenland and adjacent offshore areas. The map integrates onshore and offshore geological information and serves as a regional reference for geological interpretation, research, education and resource-related studies in Greenland.

The dataset shows global bathymetry based on The General Bathymetric Chart of the Oceans (GEBCO) 2019. The dataset represents a continuous model of seafloor topography derived from a combination of multibeam, singlebeam and satellite altimetry data. The original global grid has been reprojected to UTM zone 24N to support regional use and integration with other geological and geophysical datasets covering Greenland and the North Atlantic.

The seabed sediment map shows the distribution of seabed sediments in Danish waters and represents an integrated interpretation of sediment types within the upper approximately 0.5 metres of the seabed. Sediment classes are defined based on grain-size composition and reflect an average of the surface sediments. Glacial till is classified as a mixed sediment, while sedimentary bedrock indicates areas where deposits several million years old are exposed on the seabed. The map was updated in 2020 and builds upon the previous version from 2014, with newly mapped areas added at full level of detail. The dataset provides a nationwide overview of seabed sedimentary conditions and is used, among other purposes, for raw material mapping, marine spatial planning, and environmental assessments.
