Land resource map – AR50 Series

Description

AR50 is a nationwide dataset that shows the main types of land resources adapted to use on scales from 1:20 000 to 1:100 000. The data set consists of the following properties that can be used to produce map layers with predefined presentation rules (sld files): area type (ARTYPE), agriculture (ARJORD USE), tree species (ARTRESLAG), forest bondage (ARSKOGBON) and snauland (ARSKOGBON). AR50 is produced by generalising FKB-AR5 below the tree line and interpreting satellite imagery across the tree line. For classification of tree species, N50 forests have also been used without registered tree species where there is no AR5. Figures that are less than 15 acres do not appear on the map, but are merged with adjacent areas. AR50 is thus not suitable for spatial analyses or production of land-use statistics. The AR50 has been updated approximately every three years with the latest annual version of FKB-AR5. The production is fully automated and based on a complex rule-based production route for compiling the data sets. The latest version of the AR50 was published in May 2022 with data from AR5 and N50 from 31.12.2021, as well as new AR-FJELL2. The satellite images are from the period 2020 and 2022 (Sentinel 2 satellite). The production track was then rewritten with a new code. The code is adjusted to changes in the input data sets. The generalised figures will therefore differ slightly from previous versions. In addition, there is topological straightening including smoothing of the figures. Data is downloaded as county or municipal files. The first version of the AR50 year 2010 dataset was produced by AR5 and N50 as of 31.12.2010, and AR-FJELL with satellite imagery (IMAGE2000) from the period 1994 and 2006. It has since made annual version 2013 (AR5 and N50 as per 31.12.2013) and annual version 2016 (AR5 and N50 as of 31.12.2016). AR-FJELL has not been updated since 2010. The latest update of the first version of the AR50 has data from 31.12.2016.
