The area and zones of disease severity of the wheat leaf rust (brown rust) (pathogen - Puccinia recondita Rob. ex Desm. f.sp. tritici)

Object description Download GIS-layers

Authors:

specialist-biologist L.A. Mikhailova, GIS-specialist M.I. Saulich

Date of creation:

22.04.2003

Scale:

1:20 000 000

Accuracy of map:

Created using maps of natural scale 1:20 000 000.

Projection:

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

Basic contents:

Vector map, consisting of 3 layers and legend. Zones of distribution and disease severity are shown by polygons.

Accuracy of classifier:

Distribution and zones of severity were determined by analyzing open-published materials. Area is subdivided into zones of strong, moderate and weak disease severity.

Method of map production:

Published literature was reviewed, including Atlases, monographs and papers. Occurrence data were obtained from herbarium specimens, floras, monographs and papers. Data were then compiled through scanning and geo-referencing to develop a composite vector map. The biologist, together with the GIS specialist, drew a composite weed distribution area based on compiled data.
