Main contents:

A bitmapped map containing information about forest scarcity.

Classifier precision:

The raster layer includes three gradations: 1 - territories with forests, 0 - territories with no forest, -100 - territories outside the map.

Map compilation procedure:

The map has been compiled on the basis of the map of forests compiled by the Department of Forest Cartography of All-Union State Project and Survey Institute Soyuzghiproleskhoz (1990). All its forest varieties have been combined into a single forest layer.
