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 sources, political boundaries and ecological descriptions.

Method of map construction:

The cultivated area of Phalaroides arundinaceae was mapped according to agroclimatic, natural and economical principles of the countries of the former USSR. The vast amount of information published by the state press was analyzed. The final map was constructed by generalizing regional maps, the arable-land map (dark blue polygon), and the map of lands permitted for cultivation, excluding non-arable land (light blue polygon). Only those lands where Phalaroides arundinaceae is used in crop rotation were taken into account.
