Authors:The expert-botanist - Chuhina I.G., the GIS-Expert - Suzanskaja E.I.
Date of creation:11.12.2003.
Accuracy of map:Map was created using data from herbarium specimens and maps to the scale of 1:11,100,000-1:80,000,000.
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 polygons and points. Points represent locations of species; areas of possible distribution of species are represented by polygons.
Accuracy of classifier:Points represent locations of the species referenced in literature and locations from which herbarium specimens were taken. Polygons are based on generalized information from literature and locations from which herbarium specimens were taken. Species location data were obtained from the electronic database of site coordinates developed by the N.I. Vavilov Institute (1992) and published maps from the following sources: Mosel, (1965); Hulten & Fries, (1986); Vlasova, (1987); Grossgeim, (1940); and Baranova, (2000).
Method of map production:Published literature was reviewed, including atlases, monographs and papers. Occurrence data were obtained from herbarium specimens, floras, monographs and papers. Map boundaries were determined in the following locations according to the following sources: In the European region of the former USSR, Hulten et al. (1986); in Crimea, Mosel (1965); in the Caucasus, Grossgeim (1940) and N.I. Vavilov Institute (1992); in Siberia, Vlasova (1987) and N.I. Vavilov Institute (1992). 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.
