In addition, information about quarries on deposits and operating conditions in these. Usefullness is related to ensuring areas for existing and future extraction of gravel in municipal land use planning and zoning. Recommended useage scale is 1: 50,000. In Norwegian only. In Norwegian only.
The groundwater dataset provides an overview of the country's groundwater wells and sources, and groundwater quality. It is primarily the well drilling companies that supply reports on wells, and the data is recorded for a specific template in accordance with regulations. Reported well data are quality assured by NGU. In Norwegian only.
Sediment data show mainly the prevalence of soil types covering the bedrock surface. Most of the soils were formed during and after the last ice age. The data shows only the soil that dominates in the upper meters of the terrain surface. Thick and thin layers by other soils may occur further down in the soil profile. The dataset can be used as substrates in the overall land-use and environmental planning, vulnerability analysis, assessment of ground conditions, and groundwater and infiltration potential. Sediment data in scale range of 1: 250,000 is intended to provide a regional overview. In municipal planning for example, there is a need for more detailed soil data and data mapped in scale 1: 50,000 or better may be used. In Norwegian only.
Possibility of marine clay is based on Quaternary (superficial deposit) maps in different scales and data set for marine limit. Superficial deposit surface types below marine limit are classified according to the possibility of finding marine clay and can be roughly divided into six classes.
The map service 'Possibility of marine clay' ('Mulighet for marin leire') has been created as a guide to reading a Quaternary geological map. It is important to point out that the map service does not display new information in relation to the Quaternary map. It is also important to check the scale of the Quaternary map, and it should also be taken into account that the estimated marine limit may be associated with some uncertainty. For this reason, polygons, which cross or lie near the marine limit, are included in the classification. However, a hatch shows which part of these polygons lies above the marine limit, and which can therefore generally be disregarded with regard to the possibility of marine clay. Exceptions will be areas where other soil types are on top of marine clay, but then the latter will only occur below the marine limit.
Data for water-covered areas are not delivered below the marine limit because the surficial deposits have usually not been mapped (even if some polygons for technical reason cross the shoreline). It should be noticed, however, that marine clay deposits are common within water-covered areas below the marine limit including new, loose sediments. See below and use above link 'Display productpage' to read more about the application including uncertainties and use (only in Norwegian). Can be used for overall screening of large areas for possible occurrence of marine clay. Other types of data may help to verify whether marine clay is present or not, such as ground drilling data. The map service 'Possibility of marine clay' ('Mulighet for marin leire') must NOT be used WITHOUT the data set for Marine limit.
Marine limit (ML) indicates the highest level reached by sea after last glaciation. This will depend on where you are in Norway and varies between 0 and 220 m. ML therefore indicates the highest levels of marine sediments (marine and fjord provisions) that are raised to dry land. Issues involving for example clay and landslides in marine clay can thus be ruled above ML but is relevant in several places below ML. Furthermore, clay can limit the distribution of aquifers (sand/gravel) and groundwater quality may be affected by salt water. In Norwegian only.
Bedrock N50 (1:50.000) Bedrock data shows the prevalence of the different rocks on the earth's surface. The data set consists of polygons/surfaces and boundaries. The data is based on the printed bedrock geological map series at a scale 1: 50,000. Knowledge of bedrock plays an important role in the exploration and evaluation of various types of raw materials and natural resources, as well as in water supply, waste storage, land use and environmental planning, construction, alternative energy and assessment of natural hazards of earthquakes and landslides. Bedrock data in the scale range of 1:50,000 is suitable for municipal planning. In Norwegian only.
Bedrock N250 (1:250.000) Our bedrock data shows the prevalence of different types of rocks on Earth's surface, as well as information on structures and rock age. The data is mainly based on the nationwide printed bedrock geological map series at a scale 1:250,000. Knowledge of bedrock plays an important role in the exploration and assessment of various types of raw materials and natural resources, as well as in water supply, waste storage, land use and environmental planning, construction, alternative energy, and assessment of natural hazards such as earthquakes and landslides. Bedrock data in scale range of 1:250,000 is intended to provide a regional overview. Information on the age of the rocks (geochronology) can be found in a separate database that is available under Applications . The locations of known deposits of ore, industrial minerals, natural stone and gravel and crushed stone can be found in databases also available under Applications .

Marin - Landforms on the seabed The dataset show a series of landforms on the seabed of norwegian coastal and sea areas. Landforms can be created under influence of ice , created by landslades of sediments, created by seabed currents etc. Knowledge of landforms gives the understanding of the processes in the marine environment, both these that shaped the seabed under and just after the ice age, as well as those currently influencing the seabed today.
Marine - anchoring conditions shows anchoring and mooring conditions in selected coastal areas interpreted from depth and bottom type. It is distinguished between anchoring and mooring conditions. In an area of poor anchoring conditions (hard bottom) it may still be possibilities for mooring in bedrock at depths less than 30 m. Suggested scale for usage is 1:10 000 - 1:50 000. In Norwegian only.
The Marine landscapes dataset shows the subdivision of the seabed into marine landscapes defined as larger geographical areas with homogenous character. The classification is based on Naturtyper i Norge (NiN). The classification is based on bathymetric data with 50-500 m resolution which means that means that the level of detail varies from one area to another. Suggested scale for usage is 1:100 000 - 1: 4 000 000. In Norwegian only.
The national radon susceptibility dataset 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 dataset 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 dataset 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. Dataset only in norwegian.
