Maps & data

NGU is the national institution for knowledge on bedrock, mineral resources, surficial deposits and groundwater in Norway. Knowledge is collected, processed and distributed compiled as maps showing physical, chemical and mineralogical properties of the country's bedrock, surficial deposits and groundwater. All maps are available through our map catalog. It is distributed both in printer friendly version and as a geographical online retrival system.  On this webpage you find all the main maps and database services NGU provide.

Arealis

Here you find information about the population of Norway. The maps cover dwellings, poluted areas, landscape, nature, landslides, waterways, coastal areas, fisheries, cultural heritage amongst other.

 

Bedrock geology

NGU has carried out mapping on Norway's bedrock geology. Bedrock maps covering the entire country at a scale of 1:250.000 have been published. Here you find the online version of these maps and also the GENION database, that is designated to search for geological units in Norway

Geophysical maps and data

The national geophysics database DRAGON (DiRect Access to Geophysics On the Net) contains data on regional geophysics and ground geophysics. These databases are based on data acquired through NGU's mapping and interpretation of the Earth's magnetic field, gravity, heat flow, radioactive radiation and electrical conductivity. They also contain information on areas abroad and on the Norwegian continental shelf.

Gravel and hard rock aggregate database

The gravel and hard rock aggregate database is a digiatal map- and registrationsystem that contains information on most sand, gravel and hard rock aggregate quarries in Norway that are used as raw material for the building industry.

Groundwater

The Groundwater Section at NGU run a groundwater database (GRANADA) that contains information on wells, natural springs, groundwater resources, -quality and -surveillance. The section also run a separate website on these issues.

 

---

Literature database

NGU has collected geological literature on Norway in a database. Here you find reports and publications on geological issues.

Map catalog

This catalog lists printed maps on bedrock geology and quaternary geology and digital geographic data series. The map catalog is both available online and as a downloadable PDF-file.

MAREANO

MAREANO maps depth and topography, sediment composition, contaminants, biotopes and habitats in Norwegian waters. The surveys are conducted by NGU in cooperation with The Norwegian Mapping Authority and The Institute of Marine Research and the results are available on the MAREANO website.

Mineral resources

This database provide an overview on Norwegian deposits of metals, industrial minerals and natural stone. It provides easy access to a variety of information including map-views, facts, field descriptions and claims.

Norwegian permafrost database

The NORPERM database provides information on ground temperatures from boreholes and from miniature temperature dataloggers (MTDs) near the ground-surface. NORPERM was established during the International Polar Year (IPY) as the main legacy of the research project “TSP Norway - A Contribution to the Thermal State of Permafrost in Norway and Svalbard".

Radon gas hazard map

Radon is a colorless, odorless and tasteless gas occuring naturally as a decay product of radioactive bedrock. Radon gas from natural sources can accumulate in buildings and is concidered a health hazard. Epidemiological evidence shows a clear link between breathing high concentrations of radon and lung cancer. NGU has composed radon maps showing areas concidered hig risk for radon gas exposition. Local authorities and planning agencies can utilize these maps and implement protective measures in exposed areas.

Skrednett

Skrednett is a service provided by Norwegian Water Resources and Energy Directorate (NVE). Here you find data about landslides and landslide risks which can be used by public and private land use planning. NGU plays a central role in the implementation of landslide maps produced in cooperation with NVE. The Skrednett database also provide historic maps on landslides and the number of people perished in this kind of natural disasters throughout Norway.

---

Surficial deposits

This database provide an overview on surficial deposits in Norway. Maps on quaternary geology and data from mapping of surficial deposits, provide information that is essential for decision makers when it comes to allocation or environmental planning
