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 dataset represents a hillshade derived from the Danish Digital Terrain Model 2007 (DHM/Terrain 2007). The hillshade is produced as a cartographic overlay layer designed to enhance terrain forms and topographic structures in the Danish landscape. The dataset is suitable for visual analysis and map presentation and can be used as a background layer together with other thematic datasets. The hillshade is based on the DHM/Terrain model, which represents terrain elevation relative to mean sea level (DVR90), with buildings, vegetation and other surface objects removed. The original terrain model is based on nationwide airborne LiDAR surveys collected during 2005–2007 and subsequently processed and quality assured.

This dataset shows the percentage nitrogen retention in Denmark, i.e. the proportion of nitrogen leached from the root zone that is transformed or retained in the subsurface and surface waters before reaching the coast. Nitrogen retention is calculated using the National Nitrogen Model and represents an average retention for the period 1990–2010. The dataset provides nationwide coverage of spatial variations in nitrogen retention and is used as a basis for assessing nitrogen transport and coastal nutrient loading. The National Nitrogen Model version 2020 is documented in National Nitrogen Model – version 2020, a GEUS special report, including a method report (ISBN 978-87-7871-551-7) and an appendix (ISBN 978-87-7871-552-4), both available from GEUS (in danish).

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 seamless digital geological map is based on the digitisation and harmonisation of 21 geological map sheets at 1:100 000 scale, originally published by GGU/GEUS between 1966 and 2011. This edition updates and expands the 2019 version, which included 16 sheets, by integrating five additional 1:100 000 sheets and selected information from 1:500 000 scale maps in areas lacking detailed coverage. The map also incorporates a simplified geological interpretation of Bjørneøen and Storeø in Godthåbsfjorden based on detailed mapping by Claus Østergaard (2005). The dataset provides a consistent, seamless geological framework optimised for digital display at the 1:100 000 scale.

The dataset comprises a collection of geological cross sections from Greenland derived from multiple geological mapping projects and publications. The cross sections represent interpretations of subsurface geological structures and stratigraphy across selected regions and are associated with published geological maps and reports. Profile lines have been georeferenced, and the corresponding cross-section images have been digitised and stored as separate PDF files. Each profile is linked to the geological map or publication from which it originates. Due to the diverse origins of the profiles, the level of detail, scale and geological interpretation vary between individual cross sections.

The National well database (Jupiter) among other things contains water level measurements from Danish wells. The database contains water level measurements from the municipalities, the groundwater-monitoring program, the regions soil pollution investigations and from the establishment of new wells.

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.
