1:20,000,000.Accuracy of map:
Created using maps of scale 1:12,000,000-1:40,000,000.Projection:
"Alber.s Equal Area Conic for the USSR", 9, 1001, 7, 100, 0, 44, 68, 0, 0.The basic contents:
Vector map. Species distribution indicated by polygons.Accuracy of classifier:
Species distribution is based on location coordinates of germplasm accessions and herbarium specimens of the Vavilov Institute and published maps from Grossgheim (1939), Shelyak-Sosonko (1977), Malyshev & Peshkova (1990), Busik (1979), Buhteeva et al (1990) and Ivanov & Buhteeva (1975).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:
