Created using materials from the literature.Projection:
"Alber's Equal Area Conic for the USSR", 9, 1001, 7, 100, 0, 44, 68, 0, 0.Basic contents:
Vector map. Area of distribution is shown by polygon (basic distribution). Zones of weediness are shown by polygons.Accuracy of classifier:
Area of distribution, which coincides with the zone of harmfulness, is established according to the analysis of the open-published literature given below.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 composite weed distribution area based on compiled data.Reference citations:
