Date of creation:
10.12.2003.Scale:
1:20 000 000.Accuracy of map:
Created using maps of natural scale 1:15 000 000-1:100 000 000 and information taken from published literature.Projection:
"Alber's Equal Area Conic on the USSR", 9, 1001, 7, 100, 0, 44, 68, 0, 0.Basic contents:
Vector map. Area of distribution is shown by polygons (basic distribution) and by points (sporadic distribution). Zone of harmfulness is shown by polygons.Accuracy of the classifier:
Distribution area and zones of weediness are based on an analysis of cartographic materials published in the literature. Maps from Kharkevich (1989) were used as a base map, supplemented by information from the below-mentioned sources. The northern and western boundaries of the area were outlined according to the same source. Borders of zones of weediness are based on Nikitin (1983).Method of map production:
Published literature was reviewed, including Atlases, 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.Reference citations:
