Object description Download GIS-layers

Authors:

Object specialist-T.D. Sokolova,
GIS-specialist-I.A.Budrevskaja

Date of creation:

22.12.2003

Scale:

1:20 000 000

Accuracy of the map:

Created using maps of natural scale 1: 5 000 000 - 1:80 000 000 and historic literature.

Projection:

"Alber's Equal Area Conic for the USSR", 9, 1001, 7, 100, 0, 44, 68, 0, 0

Basic contents:

Vector map. Area is shown by polygons (basic distribution) and by points (sporadic distribution). Zone of harmfulness is shown by polygons

Accuracy of the classifier:

Within weed area the zones of basic and sporadic distribution are shown, as well as zone of high weed infestation, where Stellaria graminea is reported to be a pernicious weed.

Method of map production:

Published literature was reviewed, including Atlases, monographs and papers. Occurrence data were obtained from herbarium specimens, floras, monographs and papers. Areas of general distribution, sporadic distribution and areas of high infestation were established according to the analysis of the open-published maps and literature. The area of Stellaria graminea was based on the map from Hulten & Fries(1986). Limits of the zone of harmfulness were established according to: (Spiridonov et al., 2000); (Ulyanova, 1983); (Shlyakova, 1982); and adjusted using the boundaries from the Arable Land Map. 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.
