Date of creation:
11.11.2005.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:
Zone of the disease distribution is allocated by results of the analysis of open published materials (Nemlienko, 1957; Kalashnikov, Shapiro, 1962).Procedure of map drawing:
Blank map with outlines of area of sclerosporosis has been scanned. The analysis of literature data shows that the disease occurs in Kuban region and in Ukraine. Registration and vectorin of raster map have been performed by standard tools of current GIS-technologies.Sources of data:
Kalashnikov K.Ya., Shapiro I.D. 1962. Pests and diseases of maize. Leningrad: Sel.khozgiz, 189 p. (in Russian).Nemlienko F.E. 1957. Diseases of maize. Moscow: Sel.khozgiz. 230 p. (in Russian).
