The national land resource database was established by NIBIO through field inventory recorded onto analogue aerial photographs mainly in the period 1964–1994 using a detailed classification system. Data were presented in analogue economic maps at scale 1:5000 published by the National Mapping Authority. Today, the original land cover map layers of land cover has been digitized and are currently managed and made available as a historical Digital Land Type Map (DMK).  In 2008, the dynamic content of DMK was extracted and defined as a new dataset called AR5. In 2013, arable land has been extracted as another dataset using AR5 to identify areas which still are arable, excluding areas that have been developed or sealed off since the data were recorded some 30 years ago. AR5 is continuously being updated by municipal administrations under guidance and periodic control and editing by NIBIO.

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). \\nAR5 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.\\nFeatures 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.\\nAR5 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.
