In fact I am working on a project in this field. I am mapping landuse of
the South Ukraine http://www.openstreetmap.org/#map=10/46.9634/31.5143
I would like to see how much landuse one mapper can cover. Now when
there is the DigitalGlobe satellite imagery with good resolution and
coverage, quality displays, it becomes realistic to map all the landuse.
I map South Ukraine landuse manually in JOSM, no imports.
In the past in Siberia there was little satellite coverage, nowadays I
see that it changed too. I do not know why they do not map forests
there. Probably it's an eternal problem - too many chiefs, too few Indians.
