Íslenskur jarðvegur telst til eldfjallajarðar (Andosol) að langmestum hluta, en eldfjallajörð er jarðvegur sem myndast á eldvirkum svæðum heimsins. Eldfjallajörð hefur afar sérstæða eiginleika sem greina hana frá öðrum jarðvegsgerðum. Útbúin var einföld flokkun fyrir íslenskan jarðveg, sem m.a. byggist á alþjóðlegum flokkunarkerfum en einnig á vinnu Björns Jóhannessonar og Þorsteins Guðmundssonar. Flokkunin gerir greinarmun á i) jarðvegi auðna (glerjörð sem skiptist í melajörð, malarjörð, sandjörð og vikurjörð; ii) jarðvegi gróins lands með sortueiginleika (sortujörð, sem skiptist í brúnjörð, votjörð og svartjörð), iii) lífrænni mójörð og að síðustu iv) öðrum jarðvegi sem er margvíslegur að gerð. Í síðasta flokknum er bergjörð útbreiddust, en auk þess má nefna frerajörð sífrerasvæða og kalkjörð. Jarðvegskortið var unnið á grundvelli sniða og jarðvegssýna sem safnað hefur verið víða um landið. Kortið er á vektora formi og í mælikvarða 1:500 000. Það er m.a. hluti evrópska jarðvegskortsins. A soil map of Iceland: The Soil map classification separates between; 1) andic soils, which are Brown Andosols, Gleyic Andosols and Histic Andosols; 2) Vitrisols, soils of deserts, which are divided into Cambic Vitrisols, Gravelly Vitrisols, Arenic Vitrisols and Pumice Vitrisols iii) Histosols, and iv) other soil types such as Cryosols and Leptosols. The classification system is in part based on WRB system and Soil Taxonomy and earlier work by Björn Jóhannesson and Þorsteinn Guðmundsson (see English Summary and 1. table in http://www.moldin.net/uploads/3/9/3/3/39332633/jardvegskort_2.pdf). The map is in a coarse scale (1:500 000) and is not intended to use for particular points on the landscape. It is rather an overview. It has been incorporated into the EU soil database and the Circumpolar soil map.

Vatnsföll eru gjarnan flokkuð í þrjá flokka, dragár, lindár og jökulár eftir rennslisháttum. Mörg eru vatnsföllin þó af blönduðum uppruna vegna margbreytileika vatnasviða þeirra. Gagnasettið sýnir greiningu vatnasvæða í vatnafarsflokka, eftir því hvernig svæðið bregst við úrkomu og miðlar henni, og rennslisháttum vatnsfalla sem eiga uppruna sinn á viðkomandi svæði.

The dataset contains geochemical sample data from four company reports submitted to the Ministry of Mineral Resources (MMR) and previously to the Geological Survey of Denmark and Greenland (GEUS). The reports were originally delivered in paper format and later scanned. The geochemical data have been digitally restored through optical character recognition of scanned documents and georeferencing of sample locations. The dataset has been uploaded to the GEUS sample database with necessary adjustments to sample names and metadata. The dataset includes samples with coordinates but without geochemical analyses, as well as samples with analyses lacking unambiguous coordinates.

This dataset represents the pre-Quaternary surface topography of Denmark, including Kattegat, internal waters and the sea around Bornholm. The map provides a paleotopographic relief of the surface that existed prior to deposition of Quaternary sediments, compiled from geological borehole data, seismic surveys and topographic sources. It includes polygons with 25 m contour intervals, a 500 m grid and boundary delineations, usable in combination with a standard elevation model to determine Quaternary cover thickness. The base map was hand-drawn at 1:250,000 scale and forms a nationwide thematic map product. The map is described in DGU map series no. 44, 1994.

The dataset comprises digital element distribution maps based on geochemical analyses of stream sediments collected in West and South Greenland. The maps were produced as part of the geochemical mapping programme underlying the Geochemical Atlas of West and South Greenland. The data represent analyses of various elements in defined grain-size fractions and provide a regional overview of geochemical variations.

This group of maps, which includes the CanMatrix and CanTopo collections, is now a legacy product that is no longer maintained. It may not meet current government standards. Natural Resources Canada's (NRCan) topographic raster maps provide a representation of the topographic phenomena of the Canadian landmass. Several editions of paper maps have been produced over time in order to offer improved products compared to their predecessors in terms of quality and the most up to date information possible. The georeferenced maps can be used in a Geographic Information System (GIS). In all cases, they accurately represent the topographical data available for the date indicated (validity date). The combination of CanMatrix and CanTopo data provides complete national coverage. • CanMatrix - Print Ready: Raster maps produced by scanning topographic maps at scales from 1:25 000 to 1:1 000 000. This product is not georeferenced. Validity dates: 1944 to 2005 (1980 on average). Available formats: PDF and TIFF • CanMatrix - Georeferenced: Raster maps produced by scanning topographic maps at scales of 1:50 000 and 1:250 000. These maps are georeferenced according to the 1983 North American Reference System (NAD 83). Validity dates: 1944 to 2005 (1980 on average). Available format: GeoTIFF • CanTopo: Digital raster maps produced mainly from the GeoBase initiative, NRCan digital topographic data, and other sources. Approximately 2,234 datasets (maps) at scale of 1:50 000, primarily covering northern Canada, are available. CanTopo datasets in GeoPDF and GeoTIFF format are georeferenced according to the 1983 North American Reference System (NAD 83). Validity dates: 1946 to 2012 (2007 on average). Available formats: PDF, GeoPDF, TIFF and GeoTIFF

The dataset comprises a geological structural map of the Danish Basin at a scale of 1:500,000 showing the structure of the chalk surface (Top Chalk). The map was published in 1991 as part of the DGU Map Series no. 7 and is based on regional geological interpretation of borehole data and seismic data. The data basis includes deep onshore boreholes, seismic profiles from hydrocarbon exploration, and seismic surveys from the inner Danish waters. The map covers Denmark and adjacent marine areas and was produced to support regional geological understanding of the structure of the chalk surface in the Danish Basin.

The dataset comprises regional airborne radiometric measurements acquired in Greenland during 1975–1982 as part of systematic geophysical mapping programmes. The measurements were collected using aircraft-mounted gamma spectrometers and record natural gamma radiation from potassium (K), thorium (Th) and uranium (U). The surveys covered large parts of Greenland and were conducted to support regional geological mapping and mineral exploration. The data constitute a historical geophysical reference dataset for analyses of near-surface lithological variations and the distribution of radioactive elements.

The dataset contains polygons representing applications for mineral-related activities in Greenland, including exploration and exploitation licences. The dataset includes different processing statuses such as Approval Applications, Licence Pending and Under Review. The data are based on geographic information provided via WFS by the Ministry of Mineral Resources in Greenland and are redistributed without modification of the original boundaries. The dataset provides an overview of areas where licence applications are under review or awaiting decision.

The dataset shows the pre-Quaternary surface of Bornholm and illustrates the distribution of pre-Quaternary rock units and geological structures beneath the Quaternary deposits. The map is based on geological interpretations carried out by Helge Gry in 1960 and 1969 and was published in the journal VARV in 1977. The pre-Quaternary geology of Bornholm differs significantly from the rest of Denmark and is characterised by complex fault systems and a combination of crystalline basement and sedimentary rocks. The map represents a historical, synthesised overview of the pre-Quaternary surface and remains an important reference in geological studies.
