Object description Download GIS-layers

Authors:

Specialist-biologist M.M. Levitin,
GIS-specialist M.I.Saulich

Date of creation:

18.11.2005.

Scale:

1:20 000 000.

Accuracy of map:

It is created on information taken from the open-published literature and map of scale 1: 33 000 000.

Projection:

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

Basic contents:

Vector map. It consists of one layer characterizing the disease distribution on corn.

Accuracy of the classifier:

Zones of disease distribution are allocated by results of the analysis of open published materials (T.D. Martynyuk, 2003).

Procedure of map drawing:

Blank map with outlines of area of G. graminicola has been scanned. The analysis of literature allows to reveal only one Russian published paper where the Anthracnose leaf form in the Far East is described. Registration and vectoring of raster map have been performed by standard tools of current GIS-technologies.
