Date of creation:




Accuracy of map:

It is created on materials of maps of natural scale 1: 40 000 000.


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

Basic contents:

Vector map. It consists of one layer characterizing the disease distribution on wheat. Foci of the disease are presented by polygons.

Accuracy of the classifier:

The zones of distribution are allocated by results of the analysis of the open published materials.

Procedure of map drawing:

A blank map with outlines of area was scanned. Definition of the disease distribution was carried out on vector layer of wheat growing regions.
