1:20 000 000.Accuracy of map:
Map is based on data from herbarium specimens and on maps having the following scale: 1:10 000 000 - 1:80 000. 000.The projection:
"Alber's Equal Area Conic for Russia", 9, 1001, 7, 100, 0, 44, 68, 0, 0.Basic contents:
Map is a vector file consisting of polygon and points. Points represent locations of species; areas of possible distribution of species are represented by polygon.Accuracy of classifier:
Light-colored points are locations referenced in literature sources. Dark-colored points are locations of species that were reported from herbarium samples (N.I. Vavilov Institute, V.L. Komarov Botanical Institute). Polygon is based on generalized information from literature sources, herbarium specimens, political boundaries and ecological description. Literature used included: Grossgheim, (1967); Shishkin, (1950); Cherepanov, (1995); Tsvelev, (2000); Hulten, (1986); Moosel, (1965).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:
