Date of creation.

Scale.

1:20 000 000.

Accuracy of map.

It is created on information taken from the open-published literature and maps of scale 1: 33 000 000.

Projection.

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

Basic contents.

The vector map is composed of 3 thematic layers. Zones of distribution and disease severity are shown by polygons.

Accuracy of the classifier.

Within the limits of the disease area two zones of severity are allocated that coincide with the greatest areas of peas culture growing. In the zone of high severity the Rust development gets character of epiphytoty in damp years and results in reduction of yield by 30%. In the zone of low severity the disease develops sparsely and rarely, having no appreciable harm.

Procedure of the map drawing.

Severity and distribution zones for the Rust of Peas are drawn on a map according to the literature data published in the open press. The analysis of the data has shown that the Rust is the most dangerous disease in the Central Black Earth zone of Russia, Volga Basin Region, Forest-Steppe Ukraine, Western Siberia, and Ural (Evdokimova et al., 1992; Korobeinikova et al., 1964; Mikhailenko, 1971; Morozova et al., 1964; Proskuryakova, 1989). Weak development of the disease is marked in Non-Chernozem and Central zones of Russia, in Baltic States, Byelorussia, and Eastern Siberia (Brundza, 1961; Dorozhkin et al., 1978; Chumakov et al., 1962). The zone of the disease distribution is adjusted to areas of the greatest distribution of peas according to I.E. Koroleva's vector layer (Koroleva et al., 2003). A vectoring of the scanned raster map with the image of disease distribution and severity is carried out by standard GIS-technologies.
