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 of five layers. Area of species distribution is shown by polygons. Zones of recorded mass outbreak and harmfulness are shown by polygons.Accuracy of classifier:
Depending on economic significance, the zone of moderate (unstable) harmfulness is separated within the area of distribution. Periodicity of the pest population raising and mass outbreaks were selected as a classifier. Population raising and mass outbreaks are registered at least every 5th year in the zone of moderate harmfulness.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:
