Main content:

A bitmapped map containing information on soil salinization depth.

Classifier precision:

Soil salinization degree is estimated by the four-point scale:
0 : > 5 m (no salinization)
1 : 2-5 m
2 : 1-2 m
3 : 0-1 m

Map compilation procedure:

The soil salinization depth layer has been obtained on the basis of the generalized Russian Soils Map (1993) (scale - 1: 4 000 000) which was combined with the database linking the skeleton of the soil types' map with the data about salinization depth of soils of the given type.

Data sources:

Russian Soils Map. scale 1 : 4 000 000. Roskartografiya Publishers, 1993.
