1: 20 000 000.Accuracy of map:
It is created on information taken from the map of scale 1: 33 000 000.Projection:
"Alber's Equal Area Conic for the USSR", 9, 1001, 7, 100, 0, 44, 68, 0, 0.Basic contents:
The vector map is composed of 4 thematic layers, where area and harmfulness zones are shown by polygons.Accuracy of the classifier:
Natural habitat of PVY coincides with zones of severity. The area of distribution is divided into four zones of severity according to Chesnokov (1961). In the zone of high severity, where numbers of aphids are constantly high, the disease development on potatoes is more than 20% and can reach 90%. In the zones of low and middle disease severity, the disease development is 5-10% and 11-20%., respectively.Method of map production:
The area and zones of severity are drawn on a blank map based on published references. Natural habitat of PVY includes all regions where potato is grown. The zone of low severity includes northern and north-western regions of Russia, Byelorussia and Baltic States. Central regions of Russian European part, Upper Volga region, some regions of Western Siberia, and agricultural lands to the East from Irkutsk Region to Primorskii Territory and Sakhalin are located in the moderate severity zone. The zone of high severity includes Kazakhstan, Moldova, Ukraine (Chesnokov, 1961). Correction of severity zones was carried out according to Koroleva.s map (Koroleva, 2003) characterizing territories of the largest potato distribution. In particular, the zone of the disease high severity is extended along potato distribution territories in the countries of Central Asia.Reference citations:
