Authors:

Biologist - F.A. Karlik

Date of creation:

07.04.2003.

Scale:

1:20,000,000.

Accuracy of map:

Created based on materials of maps of natural scale 1:12,000,000; 1:45,000,000.

Projection:

"Alber's Equal Area Conic for the USSR" 9, 1001, 7, 100, 0, 44, 68, 0, 0

Basic contents:

Vector map of 4 layers and legend. Zones of distribution and harmfulness are shown by polygons.

Accuracy of classifier:

Depending on economic significance, the area is divided into zones of strong (stable) and weak (unstable) harmfulness. Periodicity of the rising pest population and mass outbreaks were selected as a classifier for each zone. Rising population and mass outbreaks have been registered at least every 2nd-3rd year in the zone of strong harmfulness and at least every 8th year in the zone of weak harmfulness.

Method of map production:

Open-published original maps of the area and zones of harmfulness were scanned. Registration and vectorization of raster maps were executed using standard tools of GIS.
