Map was created based on materials of maps of natural scale 1: 33 000 000.Projection:
"Alber.s Equal Area Conic", 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:
On the map the zones of Loose Smut distribution and harmfulness are presented.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 areas of fungus distribution were determined according to the following sources: Ishkova et al. (2002), Levitin & Tuterev (2003). The zone of harmfulness was determined according to the following sources: Rudenko et al. (1966), Timoshenko (1973), Utesheva (1977), Karatyghin (1986).Reference citations:
