Authors:

Specialist-biologist E.L. Gasich, GIS-specialist M.I. Saulich.

Date of creation:

11.09.2004

Scale:

1:20 000 000.

Accuracy of map:

Map was created based on materials of maps of natural scale 1:33 000 000.

Projection:

"Alber.s Equal Area Conic", 9, 1001, 7, 100, 0, 44, 68, 0, 0.

Basic contents:

Vector map. Area of species distribution is shown by polygons.

Accuracy of classifier:

The disease distribution was presented in regions where the Phyllosticta Leaf Spot has been found according to scientific publications.

Method of map production:

Scientists were given maps with boundaries of Oblasts and arable lands. After reviewing historic literature, species distribution was hand drawn on maps. If data were on the Oblast-level, distribution is on the Oblast level. In some cases, Oblast.s are further refined by boundaries of the Arable Land Map (Koroljeva et al., 2003). Hand drawn maps were scanned, georeferenced and vectorized. The disease is distributed throughout the Primorskii Territory according to the literature of Abramov (1939) and Dorofeeva et al. (1992).
