The dataset comprises airborne electromagnetic (AEM) measurements acquired in Greenland during 1994–1998 as part of GEUS’ regional geophysical mapping programme. The surveys were conducted using helicopter- and fixed-wing electromagnetic systems and include electromagnetic response measurements as well as magnetic data. The dataset is used for regional mapping of subsurface electrical conductivity and for identifying structural and lithological variations relevant to geological interpretation and mineral exploration.

EOxCloudless is a global satellite imagery dataset consisting of near-cloudless mosaics derived from Copernicus Sentinel-2 multispectral satellite data. The dataset is produced by EOX IT Services GmbH and is designed to provide consistent, high-resolution surface imagery for mapping, analysis, and visualization purposes. The mosaics are generated by combining a large number of Sentinel-2 Level-1C observations acquired over defined time periods. Advanced pixel selection algorithms and thematic masks (including clouds, cloud shadows, and water) are applied to reduce cloud contamination. For each pixel location, the most representative observation is selected based on statistical criteria and temporal analysis, resulting in near-cloudless composite images. The dataset provides global land coverage and is typically delivered at a spatial resolution of 10 metres for the utilised spectral bands (blue, green, red, and near-infrared). EOxCloudless is suitable for use as a basemap as well as for environmental monitoring, land analysis, spatial planning, and other geoscientific applications.

The dataset comprises a geological map of the Danish Central Graben at a scale of 1:200,000 presenting regional maps of ‘Base Chalk’ and the Chalk Group in terms of two-way travel time, depth, interval velocity and vertical thickness (isochore). The map was published in 1995 as part of the DGU Map Series no. 48 and was produced as part of a comprehensive geological mapping of the Danish Central Graben. The mapping is based on regional interpretation of seismic data supplemented by information from boreholes. The map covers the Danish part of the Central Graben and parts of the eastern North Sea, and adjacent areas in the Norwegian, British and German sectors are included in order to define regional structural relationships. The map sheet consists of several thematic sub-maps that together describe the structure and stratigraphy of the area.

The dataset comprises a geological map of the Danish Central Graben at a scale of 1:200,000 presenting regional maps of the Base Upper Jurassic and the Upper Jurassic. The map was published in 1995 as part of the DGU Map Series no. 50 and was produced as part of a comprehensive geological mapping of the Danish Central Graben. The mapping is based on regional interpretation of seismic data supplemented by information from boreholes. The map covers the Danish part of the Central Graben and parts of the eastern North Sea, and adjacent areas in the Norwegian, British and German sectors are included in order to define regional structural relationships. The map sheet consists of several thematic sub-maps that together describe the structure and stratigraphy of the area.

The dataset consists of three different datasets with combined place names in various geological maps: Geological map of Greenland 1:2.500.000, Geological maps of Greenland 1:500.000 and Topographic map of Greenland 1:250.000. The dataset has not been updated or maintained since 2014.

The Regional AEROMAG 1992–2013 Surveys comprise a compilation of high-resolution airborne magnetic surveys acquired by GGU/GEUS between 1993 and 2013 and financed by the Government of Greenland. The overlapping surveys cover approximately 300,000 km² and include the total ice-free onshore areas and near-coastal offshore regions of West Greenland, South Greenland and southern East Greenland. All surveys were acquired using aircraft with similar flight parameters, including line spacings of 500–1,000 m and cross-line spacing of approximately 5,000 m, and with flight altitudes of about 300 m above ground level or seafloor along gently draped surfaces. These consistent acquisition parameters allow the individual surveys to be integrated into a coherent, high-quality regional magnetic data compilation. The total magnetic anomaly map was generated by merging grids from separately processed datasets using the grid-knitting module in Oasis Montaj. The data are IGRF-corrected but not reduced to the pole, and the crustal magnetic field model MF7 was used as a regional reference grid during compilation.

This dataset is based on the Geological Survey of Denmark map series no. 45 and represents a compiled geological map product produced in the early 1990s. The map is based on existing geological maps, seismic surveys, and previous interpretations, providing a regional overview of the geological conditions within the mapped area. The dataset forms part of the national mapping activities of the Geological Survey of Denmark and was published in 1994.

The dataset consists of a series of ASTER band ratios combined into colour composite images designed to highlight mineralogical distributions and lithological variability in Northeast Greenland. The ASTER scenes were preprocessed with atmospheric, radiometric and topographic corrections, including radiative transfer modelling using ATCOR-3 in rugged terrain mode. A surface elevation model was applied to adjust illumination effects. Non-outcrop pixels were masked prior to generating the final mosaic. Calibrated radiance data were converted to apparent surface reflectance; however, further calibration against ground-based reflectance measurements was not feasible. The dataset represents a derived remote sensing product and not primary satellite data.

The dataset comprises a geological map of the Danish Central Graben at a scale of 1:200,000 presenting regional maps of ‘Top Chalk’ and the Post-Chalk Group in terms of two-way travel time, depth and interval velocity. The map was published in 1995 as part of the DGU Map Series no. 47 and was produced as part of a comprehensive geological mapping of the Danish Central Graben. The mapping is based on interpretation of seismic data supplemented by information from boreholes. The map covers the Danish part of the Central Graben and parts of the eastern North Sea block, and adjacent areas in the Norwegian, British and German sectors are included where data were available in order to define regional structural relationships. The map sheet comprises several thematic sub-maps that together describe regional variations in structure and stratigraphy.

The dataset comprises a geological map of the Danish Central Graben at a scale of 1:200,000 presenting regional maps of ‘Base Cretaceous’ and the Cromer Knoll Group. The map was published in 1995 as part of the DGU Map Series no. 49 and was produced as part of a comprehensive geological mapping of the Danish Central Graben. The mapping is based on regional interpretation of seismic data supplemented by information from boreholes. The map covers the Danish part of the Central Graben and parts of the eastern North Sea, and adjacent areas in the Norwegian, British and German sectors are included in order to define regional structural relationships.
