Authors:

Specialist-biologist E.I.Gultyaeva, GIS-specialist M.I.Saulich

Date of creation:

23.09.2003

Scale:

1:20 000 000

Accuracy of a map:

It is created on materials of map of natural scale 1: 40 000 000,

Projection:

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

Basic contents:

Vector map. It consists from 1 layer characterizing the disease distribution on wheat. Focuses of the speckled snow mold are presented by polygons.

Accuracy of the classifier:

Evidences of diseases occurrences on winter wheat in administrative-territorial areas were extrapolated for full areas but in basis in places where ploughing of areas reached to 70% and more. In some cases the border of polygons was marked according to districts concurs where winter wheat was mostly distributive (Bashkortostan) .

Procedure of map drawing:

The copy of blank map composed from base vector layers (borders of former USSA and independent countries, borders them administrative-territorial formation, main wheat growing regions, coordinate grid) was used. The zones of distribution are allocated by results of the analysis of the materials published in an open edition ( Potatosova, 1960; Andreeva, Tupenevich, 1963; Kaask, 1963; Artem.eva et al, 1969; Sidorova, 1973; Sanin, 2000; Seraya, 2001). Elements of enumerated higher base layers were used for spatial orienting point. The blank map with the focuses of Typhula sp. distribution has been scanned. Registration and vectoring of raster map were performed by standard tools of current GIS-tecnologies. Definition of disease distribution was carried out on vector layer of regions were winter wheat are grown.
