- SLU Forest Map contains spatial information with a high degree of detail over most of Sweden's forest land 1.
- SLU Forest Map contains information on age, height, species, and standing volume of the country's woodlands.
- The format is raster data with a resolution of 25×25 m using the Swedish projection RT90 2.5 gon V.
- The satellite images used are from LANDSAT 5 and LANDSAT 7 (SLU Forest Map 2000) and from SPOT 4 and SPOT 5 (SLU Forest Map 2005 and 2010).
- Raster layers can be used in geographic information systems (GIS) to visualize and analyze on local, regional, and national level.
About SLU Forest Map
Demand for up to date digital information about our forests in increasing a rapid pace. The same is true for the use of geographic information systems (GIS). Many users want to see how much forest there is in a specified area, estimate its average age, and to see which tree species it contains.
SLU Forest Map contains spatial information with a high degree of detail over most of Sweden's forestland. SLU Forest Map is based on a combination of data from the Swedish National Forest Inventory and satellite data. SLU Forest Map is primarily intended for use with larger areas of forestland. If the area is less than a few hundred hectares then the information should be used with a degree of caution.
SLU Forest Map is available free of charge as either a download or within our web based GIS application.

SLU Forest Map was previoulsy known as kNN-Sweden. This name comes from the method used, k Nearest Neighbours.
kNN-Sweden is developed and produced by the Remote Sensing Laboratory, Forest Resource Management, Swedish University of Agricultural Sciences in Umeå, Northern Sweden.
