Date of creation:
31.03.2003.Scale:
1:20.000.000.Accuracy of map:
Map was created based on materials of maps of natural scale 1: 40 000 000.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:
Area in the FSU and Baltic countries is presented by zones including all regions where loose smut wheat was registered according to data published. Zones of disease distribution are shown on the map. Extent of harmfulness caused by common bunt fluctuates annually and depends on carrying out prophylactic actions (seed dressing and resistant varieties usage).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.Reference citations:
