Land resource map — AR50 — forest bondity
Description
Map layers in the nationwide data set AR50 that show production capacity/bonity in forest area by scale 1:50 000 and are adapted to use on scales from 1:20 000 to 1:100 000. Forest yield is a measure of the area’s ability to produce wood. Property in the data set to be used to produce the map layer is called ARSKOGBON in SOSI format and forest bondity in gml and gdb format. AR50 is produced by generalisation of FKB-AR5 below the tree limit and interpretation of satellite images above the tree line. In addition, N50 forests have been used without registered wood species where there is no AR5. Shapes smaller than 15 acres do not appear on the map, but are merged with adjacent areas. The dataset is thus not suitable for compiling land use statistics. Legal property values according to the code list are: 18 — High and very high; 13 — Medium; 12 — Low; 11 — Impediment; 98 — Not applicable. The data set has been updated once every three years with the last year’s version of FKB-AR5 (area resource map on a scale of 1:5000 in the database as of 31.12). The latest update has data from 31.12.2019.
The first version of the AR50 data set (year version 2010) was produced by AR5 and N50 as of 31.12.2010, as well as AR-FJELL with satellite images (IMAGE2000) from the period 1994 and 2006. Annual version 2013 (AR5 and N50 as of 31 December 2013) and annual version 2016 (AR5 and N50 as of 31.12.2016). AR-FJELL has not been updated since 2010.
The second version of the AR50 data set (year version 2020) was produced by AR5 and N50 as of 31.12.2021, as well as AR-FJELL2 with sentinel-2 images from the period 20XX-20XX. The production trail has been rewritten with new code. The codework is adjusted to changes in the input data sets. The generalised figures will therefore differ slightly from previous versions. In addition, there is topological correction including smoothing of the figures.
Data is downloaded as county or municipal files. There is no need to download the data set more than once to produce all the map layers in the dataset.
