Nationwide geophysical database for environmental and raw material data, also known as GERDA (GEophysical Relational DAtabase). The database contains various types of geophysics, including geoelectrics, electromagnetics, borehole logs and seismic. All data is freely available for download on the GEUS website. The database is updated continuously.

The dataset represents an index layer showing the geographic extent of archived and unpublished historical geological maps and sections from Greenland.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.

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.

This dataset depicts the depth to the top of the pre-Zechstein succession in the Danish subsurface. The map represents the structural surface beneath the Zechstein evaporites and provides a regional overview of the geological framework of the subsurface. The dataset is based on interpretation of seismic data, deep boreholes and previous geological mapping and was produced as part of the Geological Survey of Denmark map series no. 45. The map is used as a reference for regional structural geology and subsurface modelling.

The dataset is based on OpenStreetMap (OSM) data downloaded from the official OpenStreetMap distribution platform. The data have subsequently been processed and published as a customised web service. OpenStreetMap is an open, crowdsourced geospatial dataset that is continuously maintained and updated by a global community of contributors. The dataset contains vector-based geographic features, including transport networks, buildings, land use, hydrography, natural features, and points of interest. The data are used as a background map and reference dataset for map visualisation and spatial analysis at local, regional, and national scales. Data content and quality vary geographically and depend on contributor activity.

The service contains GEBCO, VMAP0 data at higher zoom levels, and data from the national mapping authorities of Canada, Denmark, Finland, Iceland, Norway, Russia, Sweden and USA. The service has been designed for use within the ArcticSDI Geoportal.

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.

This dataset contains a seamless digital geological map of the Karrat area in central West Greenland based on four geological map sheets at a scale of 1:100 000: Maarmorilik 71 V.2 South, Nuugaatsiaq 71 V.2 North, Pannertooq 72 V.2 South and Svartenhuk 71 V.1 North. Geological mapping was carried out in the fjord regions north of Uummannaq as part of a collaborative project between the Geological Survey of Denmark and Greenland (GEUS) and the Ministry of Mineral Resources and Justice of Greenland. The dataset is based on 3D photogeology using more than 35,000 oblique photographs collected during three field seasons combined with traditional field observations and subsequent geochemical and geochronological analyses. The dataset provides an updated geological understanding of the meta-sedimentary and meta-volcanic rocks of the Karrat Group, the structural evolution of the Rinkian Orogen and the structure of the West Greenland Basalt Group. The dataset supports geological research, regional geological mapping and mineral exploration.

The dataset comprises a combined geological map of the Danish Basin showing the distribution, depth conditions, and thickness variations of the Top Triassic and Jurassic–Lower Cretaceous units. The maps illustrate the regional structure and stratigraphic framework of the basin and provide an overview of its geological development from the Late Triassic to the Early Cretaceous. The presentation is based on a synthesis of borehole data, seismic information, and stratigraphic interpretations and is produced at a scale of 1:400.000. The maps were published in 1991 as part of the DGU Map Series No. 30.
