Scale:

1:20,000,000.

Exactness of map:

The map was created using maps to the scale of 1:25,000,000-1:40,000,000.

The projection:

"Alber's Equal Area Conic for Russia", 9, 1001, 7, 100, 0, 44, 68, 0, 0.

Basic contents:

Map is a vector file consisting of polygons.

Exactness of classifier:

Polygons are based on published data, political boundaries and ecological descriptions.

Method of map construction:

The cultivated area of Bromopsis inermis is based on agro-climatic, natural and economic factors within former USSR countries. The large amount of published data available was consulted. The final map was constructed by generalizing regional maps; arable lands maps (dark blue polygon); and maps of permitted, cultivated lands (excluding non-arable lands) (light blue polygon). Only those lands where Bromopsis inermis is used in crop rotation were taken into account.
