1:20,000,000.Exactness of map:
The map was created using maps that had the following scale: 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 literature sources, political boundaries and ecological descriptions.Method of map construction:
The cultivated area of Phleum pratense is based on agroclimatic, natural and economic principles of former USSR countries. territorial divisions. The vast information published in the open press was analyzed. The final map was constructed by generalizing regional maps, the arable-lands. map (dark blue polygon), and the map of lands on which cultivation is permitted, excluding non-arable-lands (light blue polygon). Only those lands where Phleum pratense is used in crop rotation were taken into account.Sources of data:
