Authors:
Object specialist V.I. Yakutkin, GIS-specialist M.I. Saulich.Date of creation:
18.03.2004.Scale:
1:20 000 000.Accuracy of map:
Map was created based on materials taken from open-published literature and maps 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:
As the disease is found on sunflower everywhere, its distribution is shown for the area where sunflower is cultivated.Method of map production:
Scientists were given maps with boundaries of Oblasts and arable lands. After reviewing historic literature (Peresypkin, 1974; Tikhonov, 1975; Yakutkin, 2001) 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.Reference citations:
