Geological surface map of Denmark 1:25.000

This dataset represents a nationwide digital geological map of superficial deposits in Denmark at a scale of 1:200.000. The map shows the classification and distribution of near-surface deposits, primarily glacial and post-glacial sediments. The dataset is based on the Digital Soil and Sediment Map of Denmark at 1:25.000 in areas where detailed mapping is available. In other areas, the distribution of deposits has been interpreted based on borehole data, landscape analysis and other available geological information. The deposits are classified into 12 generalised types, making the dataset a simplified and generalised version of the detailed 1:25.000 map. The dataset provides a national overview of superficial deposits and serves as a reference for regional and national applications. Official metadata Purpose The purpose of the dataset is to provide a consistent, nationwide digital map of superficial deposits in Denmark. The map is used as a basis for geological interpretation, environmental management, land-use planning, resource assessment, as well as education and research. Supplemental Information The dataset is an interpretation-based national map product and is not subject to continuous updates. It represents a generalised overview of the distribution of superficial deposits at the ground surface and should be used in conjunction with more detailed maps and local data where higher spatial resolution or detailed stratigraphic information is required. Lineage The dataset was compiled by the Geological Survey of Denmark and Greenland (GEUS) and represents version 2 of the digital superficial deposits map at a scale of 1:200.000. The map is based on the compilation and harmonisation of existing geological maps, borehole data, geomorphological analyses and previous Quaternary geological investigations. Version 2 includes updates and improvements compared to earlier versions, including revised deposit boundaries and classifications based on new knowledge and quality assurance. During compilation of the dataset, generalisation and adjustments have been applied in certain areas, resulting in a spatial uncertainty of up to approximately 200 m, locally slightly more. The dataset is designed as an overview map at a scale of 1:200.000 and is suitable for educational purposes, regional-scale analyses and as background information for other thematic maps. The dataset is not subject to continuous updates and was published in GEUS Report 2011/19. Mapping of superficial deposits in Denmark has been a core task of the Danish geological surveys since the establishment of the Geological Survey of Denmark (DGU) in 1888. The digital superficial deposits map at a scale of 1:200.000, version 2, builds on this long mapping tradition but represents a modern digital compilation and interpretation based on more recent data and methods.

Havbundssedimentkortet, der er opdateret i 2020, viser den geografiske fordeling af havbundssedimenterne i de danske farvande. Den givne sedimentklassificering repræsenterer den primære sedimenttype i de øverste 0,5 m af havbunden. Hver sedimentklasse er defineret ud fra den specifikke kornstørrelsesfordeling. Morænel er dog et blandet sediment af ler, sand og grus, og sedimentære bjergarter udtrykker tilstedeværelsen af aflejringer med en alder på flere millioner år og forskellig historie. På grund af den ujævne datafordeling er klassificeringerne baseret på interpolationer mellem datapunkter sammen med kendskab til den geologiske historie, vanddybder og havbundens morfologi. Derudover er tilgængelig biologisk information (fordeling af alger, ålegræs, muslingebanker osv.) inkluderet som baggrundsinformation. The Seabed sediment map, which is updated in 2020, shows the spatial distribution of the seabed sediments in the Danish waters. The given sediment classification represents the major sediment type of the upper 0.5 m of the seabed. Each sediment class is defined based on the specific grain size distribution. However, till is a mixed sediment of clay, sand and gravel, and sedimentary rocks express the presence of deposits with an age of several million years and different histories. Due to the uneven data distribution, the classifications are based on interpolations between data points together with the knowledge of the geological history the water depths and seabed morphology. Furthermore, available biological information (distribution of algae, eelgrass, mussel beds etc.) has been included as background information.

Topographic maps of Denmark describe the terrain with landscape forms, land use, buildings and roads, and provide an overview of the landscape and the various geographical elements of an area. The card in 1:25,000 is suitable for oriented and can be used for e.g. planning, nature management and teaching. The card is also suitable for printing.
