1:20.000.000.Accuracy of map:
Map was created based on materials of maps of natural scale 1: 12 000 000 and 1: 40 000 000,Projection:
"Alber's Equal Area Conic for the USSR", 9, 1001, 1, 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 is presented by foci in the FSU regions where the dwarf bunt on wheat was registered according to data published.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 Zaharova (1971) was used as a base map and the areas of Kyrgyzstan, Turkmenistan and North Osetia were adjusted according to Koshelyaeva & Dostsenko (1991), Skripka (1998) and Manukyan (2003).Reference citations:
