Date of creation:

08.01.2005

Scale:

1:20 000 000

Accuracy of map:

Map was created based on materials of map of natural 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:

Vector map. Area of species distribution and zones of disease severity are shown by polygons. The zone of distribution coincides with the zones of severity.

Accuracy of classifier:

Zones of the disease distribution were allocated according to the results of the analysis of the following open published materials: Erokhina (1990), Sidorov (1990), Aleksandrov (1992), Gopalo et al. (1995), Sotchenko et al. (1998).

Method of map production:

Scientists were given maps with boundaries of Oblasts and arable lands. After reviewing historic literature, species distribution was hand drawn on maps. If data were on the Oblast-level, distribution is on the Oblast level. In some cases, Oblast.s are further refined by boundaries of the Arable Land Map (Koroljeva et al., 2003). Hand drawn maps were scanned, geo-referenced and vectorized. The distribution zone of this quarantine disease was determined as a result of the literature analyzed.
