Maps being part of MarkInfo are almost exclusively based on data from the Swedish Survey of Forest Soils and Vegetation, where a co-ordinate system based on RT 90, the Swedish National Grid, is used to describe geographical positions. For most of the processing, including production of maps, the Statistical Analyses System, SAS (SAS institute inc.) was used. Also the geostatistical programme GS+ and the map programme MapInfo have been used. Some of the maps for climate, soil types and bedrock were produced by the Geological Survey of Sweden, SGU, the Swedish Meteorological and Hydrological Institute, SMHI, and the National Board of Forestry.
How the maps based on data from the Swedish Survey of Forest Soils and Vegetation were produced is described on accompanying pages, see the navigation bar to the left (Frequency maps, Dominance maps, Mean value maps, Mean value maps with kriging, and Trend maps).
