Precision:Maps of the Russian Federation and of the former republics of the Soviet Union have been compiled on the scale of 1:20,000,000.
Projection:.Alber.s equal-area projection for the USSR., 9, 1001, 7, 100, 0, 44, 68, 0, 0.
Main content:A vector map: polygons show cultivation areas.
Content's precision:The maps contain generalized information about the cultured plant's distribution drawn from published sources, taking into consideration the map of cultivated lands of the USSR.
Map compilation procedure:The cultivation area map was compiled by combining district maps of the Russian Federation, regional maps of the former republics of the Soviet Union, the map of natural and agricultural zoning, and the map of cultivated lands. A plant cultivation database comprised of 20 fields was been compiled using district and regional maps. A cultured plant distribution layer 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 reducing 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 the land is tilled. Cultured plant distribution takes into account only those areas where these plants occupy 3-5% or more of tilled land.
