The topographic map of Greenland at a scale of 1:250.000 is based on data collected from the 1930s through the 1970s and 1980s. These data formed the basis for the production of a series of 1:250.000 scale topographic map sheets, which continue to serve as the primary topographic reference for large parts of Greenland. Mapping of areas prior to 1970 was based on several historical map series, including 18 map sheets at a scale of 1:300.000 covering North Greenland produced by Lauge Koch between 1932 and 1940, 1:250,000 scale mapping of parts of Northeast Greenland conducted by the Geodetic Institute in the 1930s, and complete national coverage at 1:250.000 produced by the American Army Map Service in the 1950s. The digital topographic map of North and Northeast Greenland has been produced by the Geological Survey of Denmark and Greenland (GEUS) since 1977, based on high-precision digital photogrammetry using aerial photographs. The dataset has primarily been used as a topographic reference for geological mapping at scales of 1:100.000 and 1:500.000.

The data set shows data on ship traffic in the period 1 July 2016 to 30 June 2017 distributed in a grid of 250 x 250 meters. The data show all ships with class A AIS transponders. The data source is Havbase. The stronger the color the more passes of the route in the period. This provides a good overview of the large traffic flows.

Map showing information about drinking water hardness (dH) at the level of water supply areas of public waterworks in Denmark based on quality-assured data, extracted from the national well-database Jupiter in September 2023. The hardness degree is based on the concentration of calcium and magnesium in the drinking water and has importance, for example, for the soap dosage when washing clothes: hard water requires more soap than soft water. Drinking water hardness may vary considerably from location to location and in time. Contact your water utility company to get the updated and precise figures.

The dataset comprises a topographic map of Northeast Greenland delivered as a digital elevation model (DEM) with a spatial resolution of 8 metres. The DEM is provided as GeoTIFF and represents a seamless elevation surface covering the study area. The dataset was produced using input data from the ArcticDEM project, which is based on stereo imagery from the DigitalGlobe WorldView-1, WorldView-2 and WorldView-3 satellites. The elevation model integrates selected DEM strips recorded between 2012 and 2015 and has been processed to ensure consistency and continuity across the mosaic.

The dataset comprises geochemical analyses of 1,269 soil samples collected in Greenland from 1974 onwards as part of systematic geochemical mapping and mineral exploration programmes. Soil samples were primarily collected in areas lacking developed stream channels where stream sediment sampling was not feasible. The samples represent surface material and have been analysed for major and trace elements using various laboratory methods including X-ray Fluorescence Spectrometry (XRF), Instrumental Neutron Activation Analysis (INA), Inductively Coupled Plasma Emission Spectrometry (ICP), and Atomic Absorption Spectrometry (AAS). The dataset contains the original analytical results as received from the laboratories together with administrative information on sample location and analysed grain-size fraction. The data form part of the analytical basis for the Geochemical Atlas of West and South Greenland.

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.

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.

This dataset comprises calibrated geochemical data from stream sediment and soil samples collected in North Greenland between 1978 and 1999, supplemented by extensive reanalyses in 2011. The dataset includes selected elements relevant for the evaluation of zinc mineralisation: CaO, K₂O, Ba, Cu, Sr and Zn. A total of 2,469 stream sediment samples and 204 soil samples were included. The analytical values represent the most reliable results following systematic quality control and calibration procedures designed to eliminate bias between analytical methods and analytical periods, as described in Thrane et al. (2011). All values below detection limit are coded as 0 in the dataset. The dataset supports regional assessment of geochemical patterns and mineral potential in North Greenland.
