It is created on materials of maps of natural scale 1:5 000 000 - 1:80 000 000 and on literature dataProjection:
"Alber's Equal Area Conic" USSR, 9, 1001, 7, 100, 0, 44, 68, 0, 0Basic contents:
Vector map. Area is shown by polygons (basic distribution) and by points (sporadic distribution). Zone of harmfulness is shown by polygonsAccuracy of the classifier:
Within weed area the zones of basic and sporadic distribution are shown, and the zone of harmfulness, where Melandrium album is a pernicious weedProcedure of map drawing:
Areas of basic distribution, sporadic distribution and harmfulness are established according to the analysis of the open-published maps and literature. The area of Melandrium album is based on the maps from Hulten E., Fries M. (1986) and Volkov A.N. (1935). Limits of the zone of harmfulness are established according to Nikitin V.V. (1983) and adjusted with the limits of arable lands.Sources of the data:
