Soils 1:25 000-1:100 000

The soil map shows the distribution of soil species in or near the soil surface and the presence of blocks in the soil surface. The soil types are classified according to their method of formation and grain size composition. Superficial soil layers with a power of less than half a to one meter and soil layers at depth are reported in some cases. Some landforms, such as moraine hill landscapes, moraine ridges and air sand dunes are also reported. The purpose of the soil map is to provide a basis for analyses of groundwater conditions, the spread of pollutants in soil and groundwater, soil stability, erosion, buildability, natural values and other soil-related issues. The information in the map can be used to produce various thematic products, such as groundwater vulnerability, soil permeability, erosion sensitivity and landslide conditions. The information forms the basis for SGU's printed earth maps and various mapping services. The mapping has been done with different methods, varying geographical basis and for presentation scales from 1:25 000 to 1:100 000. This means that there are major differences in quality within the product, both in terms of positional accuracy and the division of soil types. The differences in mapping methods used in the mapping are reported by marking the information as different types of maps.
