I try find farmland on this point (in Josm I zoom to this farmland):

http://www.openstreetmap.ru/#zoom=15&lat=44.03682&lon=131.66346&marker=1

But after long time, scanaerial create big multipoligon:

Can I limit the analysis area script by zoom in josm or other method?

limiting the area would not help much. The script needs to detect the borders and i dont think that it will be ever possible to detekt grainfields, grassland and the like. I had very good results in scanning the lakes in sibiria (you can find many examples around Anadyr). These lakes have a contour with very high contrast. There are many promising ideas to improve scanaerial, but i have no time in near future to code them.
