01.02.2005.Scale:
1:20 000 000.Exactness of the map:
Map is based on data from herbarium specimans and on maps having the following scale 1:13 000 000 - 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 polygons and points. Locations of species are represented by points, areas of possible distribution of species are represented by polygons.Accuracy of the classifier:
Points represent locations of the species referenced in literature sources and from herbarium specimens. Points also submit the information with herbarium samples WIR, BIN and to collection WIR. The range is constructed on the basis of generalization of the information from references, herbarium samples and collection WIR.Method of map production:
Species location data were obtained from a database of site coordinates of the species in the INFORMATION RETRIEVAL SYSTEM " Wild-growing relatives of cultural plants of Russia " (NTC "Informregistr" № 0229905883, 1999) and from maps published by M.P.Zhukovsky (1928), A.Eig (1929), M.W. van Slageren (1994).The kind has a disjunctive area. In the European part the border of an area is carried out on data M.W. van Slageren (1994) and P. M. Zhukovsky (1928); in the Central Asian part the border of an area is carried out on the data from collection WIR and herbarium to materials BIN, WIR, the information about which is stored in a database of the information retrieval SYSTEM; east piece of an area is carried out on data A. Eig (1929); northern point of a site of a kind and two points in Kiev are not included in range because of drifting distributions of a kind to the given places.
