Map viewers

Find your way in the multitude of geochemical data at NGU! We have identified several hundred datasets from the 1960ïes onwards, that together with their respective reports are put on the map for easier access. A few clicks and swipes, and you will get an overwiev of what is available, with links to reports and data. If you need datasets, you can download these one by one, but first time around, you will have to contact geokjemidatabase@ngu.no to request a username (your email address) and a password generated by NGU. In Norwegian only.

Topic: Geochemistry

The application Geodiversity displays recorded geological localities that may be of interest to tourists, schoolchildren and wildlife managers. Some of the material is of older vintage and there might be academic shortcomings in the data set. Please feel free to propose corrections and new areas be entered. In Norwegian only.

Topic: Geological diversity, Landscape development

The national geophysics database (DRAGON) provides information on regional geophysics, ground geophysics, petrophysics and gravimetry. The DRAGON-database (DiRct Access to Geophysics On the Net) also provides information on geophysical surveys on the Norwegian continental shelf and internationally. In Norwegian only.

NGU's application for aggregates is a digital map and registry system over most of the gravel, crushed stone deposits and quarries in Norway that provide raw materials for the construction industry. The database provides information about the deposits, prioritized on the basis of location, boundaries, land-use, volume and its quality (as a construction material). The database includes entries from geographic areas and specific points. In Norwegian only.

Web map application for national radar measurements of ground motion from satellite, called InSAR. The method registers movements in millimetre scale, for example subsidence in cities and deformation in unstable rock slopes. The density of measuring points varies with the ground surface and is highest in cities and along infrastructure as well as terrain dominated by bare rock. The data originates from the satellites Sentinel-1A/1B from EUs Copernicus program recorded during 2014-2018.

Topic: Geohazards, Urban geology

NGU delivers marine geological maps covering a wide range of topics, including sediments (grain size and formation), sedimentation environments, bottom conditions, pollution, and landscape and landforms. The maps are also available at different scales to suit various users. In recent years, the MAREANO project covering the northern oceans has received much attention, but NGU also work in coastal areas and in other parts of the Norwegian waters.  The new mobilefriendly web map is available in both norwegian and english The old map is in Norwegian only.

National database for ground investigations (NADAG) shows borehole (points) where ground surveys are carried out. NADAG includes geotechnical data (boreholes) and has a view service for this. The services NADAG offers are free. Where raw data or reports are linked to the survey point, this can be downloaded free of charge. The information associated with each data point varies and partly depends on the format of data are passed on. There have been no attempts to correct errors in the data sets. NADAG and contributors are not responsible for the individual's use of the data sets. Use of data must be referenced to data owner.

This permafrost database offers information about ground temperatures from boreholes and mini loggers (MTDs) near the surface at the mainland of Norway. The database was established during the International Polar Year in 2007 as one of the main objectives of the research project Thermal State of Permafrost in Norway and Svalbard. The data is organized into study areas, giving overview information. A study area contains one or more measurement points, which in turn is (1) a borehole or (2) miniloggers measuring near-surface temperature outside boreholes. Temperature data in boreholes may be temperature series with time (monitoring) or temperature with depth (logs). Near-surface temperature data is temperature series with time only. The database may also hold photographs of study areas (overview) or measurement points (detail). In Norwegian only.

The national radon susceptibility map shows areas in Norway that might be more prone to radon (or: have greater radon risk) than others. In areas marked with high susceptibility, it is estimated that at least 20 % of the homes (houses/residences) have radon concentrations above the upper recommended limit of 200 Bq/m3 at ground floor level. The map is based on indoor measurements of radon and knowledge of geological conditions. In some areas in Norway radon has been measured in many houses, whereas in other areas there are few available measurements. The map was developed by statistically considering how the proportion of houses that exhibit high radon concentrations may relate to the local geology, and transferring this knowledge to other areas with similar geological conditions.  In Norwegian only.
