Authors:
Scientist and GIS specialist - L.L. Malyshev.Date of creation:
30.09.2003.Scale:
1:20,000,000.Accuracy of map:
Created using maps of scale 1:12,000,000-1:40,000,000, as well as collection site location data from herbaria and databases of the Department of Introduction and Department of Genetic Resources of Perennial Fodder Crops, N.I. Vavilov Institute.Projection:
"Alber.s Equal Area Conic for Russia " 9, 1001, 7, 100, 0, 44, 68, 0, 0.Basic contents:
Vector map. The area of species is represented by polygons and points.Accuracy of classifier:
Point data were obtained from literature sources and herbarium specimens (N.I. Vavilov Istitute); (Savkina et al, 1982); (Kharkevich, 1985); (Malyshev & Peshkova, 1990); (Malyshev & Peshkova, 1979). Polygons are based on literature sources, herbarium samples, and field surveys by the authors.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 new plant distribution area based on compiled data.Reference citations:
