Projection:

.Alber.s equal-area projection for the USSR., 9, 1001, 7, 100, 0, 44, 68, 0, 0.

Basic contents:

Vector map. Polygons present cultivation areas.

Accuracy of classifier:

The maps contain generalized information about the cultured plants. distribution drawn from published sources, taking into consideration the map of cultivated lands of the USSR.

Method of map production:

The cultivation areas' map was compiled using a combination of the maps of the districts of the Russian Federation, the maps of the regions of the former republics of the Soviet Union, the map of natural and agricultural zoning, and the map of cultivated lands. A plants' cultivation database comprised of 20 fields was compiled for district and regional maps. A cultured plants' distribution layer according to the administrative division was determined for each field, whereupon non-arable lands were excluded from each layer. The map of the arable lands of the former USSR was obtained by reduction of the 1:4,000 000 map of cultivated lands to the scale of 1:20,000 000, taking into account the areas where 10% or more of lands are tilled. Cultured plants' distribution takes into account only those areas where these plants occupy 3 to 5% or more of the tilled land's area.
