Authors:

Specialist-biologist E.L. Gasich, GIS-specialist M.I.Saulich.

Date of creation:

15.12.2004.

Scale:

1:20 000 000.

Accuracy of map:

It is created on materials of maps of natural scale 1:33 000 000.

Projection:

"AlberТs Equal Area Conic", 9, 1001, 7, 100, 0, 44, 68, 0, 0.

Basic contents:

Vector map consists of polygons demonstrating area of the disease distribution on rice.

Accuracy of the classifier:

The area represents the disease distribution, where the Black Smut has been revealed according to scientific publications.

Procedure of map drawing:

The area of the Black Smut has been marked on a blank map. In the former Soviet Union the disease has been registered in Primorskii Territory (Abramov, 1938; Azbukina et al., 1986; Dorofeeva et al., 1992) and also in Syr Darya Region of Uzbekistan (Dorofeeva, 1993). Registration and vectorization of raster map have been carried out using standard GIS-technologies.
