AR250 (Land Resource Map 1:250.000) - Arable land
Arable land is a valid land resource attribute for certain classes of land types derived from the dataset AR5. These land types are pasture, forest, open land and marshland (peat bog). The land types have to fulfill requirements for soil quality and climate for plant production.
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.

AR250 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) and the Arable land map at scale 1:5000.
Arable land data are updated periodically with data on from the land resource map in scale 1:5.000. This ensures that arable land are an attribute to current pasture, forest, open land and peat bog and not an attribute to previous land types.
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.

- Statement
-
Arable land was classified during field inventory and recorded onto analogue aerial photographs for the whole of Norway’s mainland below the tree line (productive area), mainly in the period 1964–1994. Arable land data are derived from the historical dataset Digital Land Type Map (DMK) which was digitized from original paper map sheets. All land type features classified as arable land on the original analogue maps sheets were identified. The map layer with arable land was later intersected with an updated version of the land resource database from 2008 providing a new map of arable land on current land types classified as pasture, forest, open land and peat bog. The dataset is annually updated with current land types from the national land resource database.
