Map was created from a 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:
Vector map. Area of species distribution and zones of disease severity are shown by polygons.Accuracy of classifier:
The distribution area of the fungus coincides with the area of pea cultivation.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, georeferenced and vectorized. The map of the distribution and severity zones of the fungus was determined according to the materials published by the following sources: Pidoplichko (1977), Bagaeva (1964), Dobrovolpskaya (1973), Khaleeva (1965). According to this data the area of the disease occupies all areas of industrial cultivation of peas (Koroljeva et al., 2003). Pskov, Novgorod, and Leningrad Regions in Northwest of Russia, and also central and some southern regions of Ukraine were added.Reference citations:
