The Digital Geological Map of Denmark 1:25,000, version 7.0, is a nationwide geological dataset describing the distribution of near-surface soil and sediment types across Denmark. The dataset is produced and maintained by the Geological Survey of Denmark and Greenland (GEUS) and represents the latest version of the digital soil and sediment map at a scale of 1:25,000. The map is based on an integrated interpretation of geological field observations, borehole data, historical analogue maps, and more recent digital datasets. Soil and sediment units are classified according to their lithological and genetic characteristics and represent the dominant materials in the uppermost geological layers. The dataset is continuously updated, and version 7.0 includes both revisions of previously mapped areas and newly mapped regions. The dataset is widely used as a foundation for geological analysis, land-use planning, environmental assessment, groundwater protection, raw material management, research, and education. In version 7 from 2023, 93% of Denmark's land area is classified, and the map is continuously supplemented. The map and sediment type description are published in GEUS report 2023/29, where further information is available.

The dataset represents a nationwide mapping of buried valleys in Denmark. The map depicts the occurrence, distribution and general geometry of mapped buried valleys in the Danish subsurface. Buried valleys are elongated depressions in the subsurface that are today fully or partly infilled with younger sediments. In Denmark, the majority of mapped buried valleys are interpreted to have formed during repeated glaciations in the Quaternary period. The valleys are typically 0.5–2 km wide and may reach depths of up to approximately 400 m. The dataset is based on interpretation of geophysical data, primarily TEM and SkyTEM surveys, supplemented by seismic data and borehole information. The mapping provides a national overview of buried valleys and forms a key basis for understanding the geological framework of the subsurface.

The dataset represents an index layer showing the geographic extent of archived and unpublished historical geological maps and sections from Greenland. The layer functions as a search and reference tool and does not contain the original map material. The dataset supports identification and access to historical geological archive documents.

The dataset contains geochemical analyses of 49 scree (talus) samples collected in Greenland as part of regional geochemical mapping programmes conducted by the Geological Survey of Greenland (GGU), later GEUS, between 1977 and 1997. Scree samples were collected in areas where neither stream sediment nor soil sampling was feasible. The samples represent near-surface material derived from local bedrock and were analysed for major and trace elements using laboratory methods available at the time of collection. The dataset supplements regional geochemical data from stream sediment and soil samples and forms part of the overall basis for geochemical mapping in Greenland.

The dataset represents an index layer showing the geographic extent of geological maps of Greenland printed and published by the Geological Survey of Greenland (GGU) and the Geological Survey of Denmark and Greenland (GEUS) since 1957. The layer functions as a search and reference tool and does not contain the original map material. The dataset provides direct links to the GEUS Dataverse, where each map is assigned a DOI and can be downloaded as high-resolution TIFF images (400 dpi) or PDF files.

The geological map of Greenland at a scale of 1:500 000 is based on 14 digitised map sheets covering the whole of Greenland, with amendments in specific areas (Pedersen et al. 2013, GEUS Bulletin, DOI: 10.34194/geusb.v28.4727). The original digital version of the map was released through the Greenland Portal in 2012. Continued advances in geological knowledge have necessitated successive revisions in order to keep the map up to date. During the most recent update, a number of geographical areas were revised based on new geological data and interpretations, including parts of West Greenland, North Greenland, North-East Greenland, East Greenland and South-East Greenland. The updated map incorporates revised stratigraphic interpretations and improved representation of geological units and structures. The map has undergone extensive quality control, including complete harmonisation of lineaments and structural elements across map-sheet boundaries. The geological legend is dynamic and reflects the content of the current map view. Geological units are supported by descriptive information, and for most map polygons links are provided to a geological unit database containing further descriptions.
