AR250 (Land Resource Map 1:250 000)

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). \\nAR250 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. \\nFeatures 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. \\nIn 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.

Specific usage

The dataset is primarily intended as a visual product for use in conjunction with land use planning, public management, agriculture and forestry. The dataset is not suitable for geometric analysis or area statistics. For analytical purposes, we recommend a combination of data from AR5 under the tree line and data from AR50 above the tree line. Note that AR5 is not available for download without an agreement with NIBIO who represents the agricultural partners in the National Spatial Data Infrastructure - “Norway Digital”.

Supplemental Information

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.

Statement

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 layers 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 a separate dataset. AR5 is continuously updated by municipal administrations under guidance and periodic control and editing by NIBIO. AR250 was established in 2012 by generalization of AR5, interpretation of satellite imagery and supplemented with topographic maps were no other feasible sources were available. AR250 is updated with information from AR5 every 3 years. Versions are available for 2010, 2013 and 2016.
