【Abstract】 On base of land use,land resource and environment databases,it is possible to integrate GIS with RS. In classification of remote sensing imagery, up to now, eye-interpretation still is the best method. We studied classification for land use by screen digitization based on tolerance controlled by gird, which could integrate remote sensing image proceeding with expert knowledge,　GIS,eye-interpretation　through interactive digitizing.更多还原
