Soil 1:20 000/1:50 000

Soil 1:20 000/1:50 000 contains material produced for land use planning, land use research and inventory, environmental management and scientific research. As a rule, the mapping scale has been 1:10 000. The data show a subsoil at a depth of 1 m (modified RT classification). The minimum size of the groundland pattern is usually 2 hectares; with the exception of islands, peatland and arable islands and geologically significant sites. A layer of ground between 0.4 and 0.9 metres thick on the subsoil is described as a topsoil. The minimum surface area size is usually 4 hectares. In addition to the painters, the material describes different geological soil formations, such as ridges and hillmorens. Other mapping sites, such as dunes and ancient beaches, are presented as line-like data.
