The spatial statistics show the extent (in square kilometres) of counties, municipalities and districts, divided into different space types such as sea, lake, forest, cultivated land, densely populated area, etc.

The CORINE (Coordination of information on the environment) program was started by the European Environment Agency (EEA) in 1985. Land cover information was introduced with the CORINE land cover (CLC) dataset for reference year 1990. The CLC database has been updated three times (CLC2000, CLC2006 and CLC2012). CLC is now implemented in all EU countries, most of the Central and Eastern European countries, as well as in Norway and Iceland (EEA 2007). \\nThe same hierarchical (three levels) classification system for land cover is used throughout the whole Europe. The first level has five classes of land cover. The second level has 15 classes the third level has 44 classes of land cover. Working scale of CLC is 1: 100.000.The smallest mapping unit is 25 hectares.

The service contains the official topographical data for Jan Mayen. Derived from the 25829 service.

Physical and biological cover of the earth's surface including artificial surfaces, agricultural areas, forests, (semi-)natural areas, wetlands, water bodies.

CLC datasets for Norway are produced by automatic generalization of existing high-resolution national land resource datasets supplemented with input from topographic maps and various public databases. The CORINE land cover maps are in general manually or semi -automatically digitized from satellite images. They reflect land use in years around 1990, 2000, 2006 and 2012. Further information can be found here: https://brage.bibsys.no/xmlui/bitstream/handle/11250/2469123/SoL-Rapport-2010-05.pdf? CLC2012 was compiled using the same method, but with CLC2006 as the basis.

The national land resource database (AR) classifies the land cover of mainland Norway according to the suitability for agriculture and natural plant production. National land resource datasets are available at scale 1:5.000 (AR5), 1:50.000 (AR50) and 1:250.000 (AR250). AR250 is the Norwegian low resolution land resource dataset, covering the entire mainland Norway. It is built and maintained for cartographic presentations at regional level (1:100.000 to 1:300.000). The dataset is not intended for spatial analysis. Features in AR250 are continuous areas represented as polygons with attributes assigned according to the classification criteria of AR250. The primary level of classification is land type (arealtype), based on a combination of land cover and land use. Second level attributes are forest site quality class (skogbonitet) and forest cover type (treslag). AR250 also includes information about arable land on current bare land, marsh or forest. In AR250, the general minimum mapping unit is 10 hectares for polygons that have identical combinations of attribute values. Smaller mapping units occur between identical land types if they have different forest cover or forest site quality. The dataset is a generalization of AR5 - the national land resource map at scale 1:5.000 - which covers all areas below the tree line (productive areas for agriculture and forestry). Above the tree line AR250 has been derived from satellite imagery (landsat-7, spot-4, IRS-1C) dating from 2005-2010. In areas with no feasible satellite imagery at the time the dataset was established, national topographic maps at scale 1:50.000 from the same period were used. The dataset is updated using generalized data from AR5 every 3 years. The current version is based on AR5 data available at the end of 2016. Satellite imagery and topographic maps are not updated.

Forest site class defines a land type according to it's timber productivity. Classes are: Very high; High; Medium; Low; Non-productive; Not relevant; Not known. Forest site class is a valid attribute for the following land types: Forest; Peat bog. The national land resource database (AR) classifies the land cover of mainland Norway according to its suitability for agriculture and natural plant production. National land resource datasets are available at scale 1:5.000 (AR5), 1:50.000 (AR50) and 1:250.000 (AR250). AR5 is a national, seamless land resource database. The dataset describes land resources (mainly land cover and productivity) based on a standardized national classification system with 104 classes. Special attention is given to the suitability of land for agricultural and forest production. Substantial areas of Norway are above the tree line. These areas are only mapped as “not classified” in AR5. Areas above the tree line have been mapped in AR50. Features in AR5 are continuous areas with the same attributes assigned according to the classification criteria of AR5 with a geometric representation as polygons. The minimum mapping unit in AR5 is 0.05 hectare (500 m2) for agricultural areas, transport networks and water bodies. Furthermore 0.2 hectare (2000 m2) is the minimum mapping unit for forest, peat bogs and open areas. For urban areas the minimum mapping unit is 0.5 hectare and 2.5 hectare for perpetual snow and glaciers. The geometric accuracy for well-defined boundaries is 2 m or better. The point density is normally between 5 and 50 m. AR5 is continually updated by municipal administrations and priority is given to agricultural- and urban areas. This is an integrated part of the maintenance of the municipal geospatial database. A centralized control and editing program is carried out by NFLI with a five year turnover period.

Vegetation maps provide a simplified image of the mosaic of vegetation types which constitute the natural plant cover. A vegetation type is a characteristic collection of plant species which will be found on places with similar growth conditions. A vegetation feature in the vegetation map is a continuous area (polygon) with the same attributes assigned according to the classification criteria of vegetation. In addition, each vegetation feature is classified according to main vetetation types (10 classes), habitats (16 classes) and suitability for sheep and cattle grazing. Today there are two mapping systems in Norway: one for detailed mapping at 1: 5000–20.000 and one for more general mapping at 1:20.000–50.000. The data on vegetation types from the detailed system can be combined with data relating to vegetation types in the general system.
