The digital terrain model of Greenland is constructed on the basis of GEUS's topographic data set from the official geological maps of Greenland in scale ratios 1:100 000 and 1:500 000. The data base is primarily supported by contour lines, coastlines and support points. The terrain model is assembled as a mosaic in sub-areas based on the map sheet frames from the geological map of Greenland in 1:500 000. The terrain model is made in the coordinate system WGS 1984 Complex UTM Zone 24N with the dimensions in a 100 x 100 m grid. Based on the digital terrain model, a shadow map of the terrain has been constructed.

The Samba database among other things contains information about deep wells in the Danish sector, acquired according to the Danish Act on the Use of the Subsoil. That is: exploration, appraisal, delimitation and production wells related to oil/gas. Also wells with other purposes such as: geothermal energy, gas storage, salt production and scientific research. The data sets contains technical, administrative and geological information about the well and about the geophysical measurements undertaken in the well (well logs and reports). Data are submitted by the company to whom the permission has been granted. The database is updated on an ongoing basis.

All active exploitation licences. The data are converted from the WFS that th ministery of mineral resources (MMR) in Greenland provides. Links are provided in the online resources

Ujarassiorit is a mineral hunt competition open to residents of Greenland. Participants can submit rock samples from Greenland to the Ministry of Minerals Ressources (MMR) for evaluation and may be selected for a prize.

The regional-scale gamma spectrometry data are associated with two collaboration projects involving the Geological Survey of Greenland (GGU) and the Danish Atomic Energy Commission’s Research Establishment. The projects' objectives were to outline areas with an elevated uranium potential in two regions of Greenland: The airborne radiometric surveys in southern and central West Greenland in 1975/76 and the SYDURAN project in South Greenland in 1979-1982. To acquire the data, four-channel gamma ray spectrometers were mounted upon an aircraft (1975/76 surveys) and a helicopter (SYDURAN project). The vehicles flew along shoreline and valley contour lines at low average terrain clearances of 100 and 50 m respectively. The data were recorded without GPS systems, and so positioning was estimated when known landmarks were passed. This means that the dataset is sparse and inhomogeneous, and the spatial accuracy remains low. The gamma-spectrometer had been calibrated at a pad facility at Risø, which enabled the conversion of recorded counts per second into simulated concentrations of radioactive components in the surface of the overflown terrain. Large parts of the data (surveys from 1975/76) were originally stored on magnetic tapes and data were transferred to datafiles in 2003 to make them digital accessible. Most data were retrieved and are now available as ASCII files.

The dataset contains outlines of geological maps of Greenland printed and published by GGU and GEUS since 1957 at various scales. The dataset contains links to the GEUS Dataverse where each map has been assigned a DOI and can be downloaded in a resolution of 400dpi TIFF-images or pdf.

The Samba database contains information about geophysical investigations made in the Danish sector, acquired according to the Danish Act on the Use of the Subsoil. The data is acquired in relation to investigation for oil/gas, geothermal energy, the storage of gas or salt. That is: Seismic (2D & 3D) acquisitions, CSEM as well as other magnetic and gravity acquisitions shipborne as well as airborne. The dataset also contains geophysical measurement performed in the deep wells and meta data about the seismic surveys. The data has been submitted by the licensees. The database is updated on an ongoing basis.

National database of earthquakes in Denmark with information on time, position, depth and size on the Mercalli scale and the Richter scale. The database is available on the GEUS website and is continuously updated. Data is freely available via the GEUS website.

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 database is updated on an ongoing basis.
