With the application of "3S"technology to country department,land use changes survey is greatly developed.Because "3S" technology has different emphases,additionally,land use change survey requires higher precision data,and at the same time the land changes more frequently,so "3S" technology integration becomes necessary and tendency."3S" integration has different mode,and which mode is appropriate lies on the land use change frequency,amount and economy and so on,which can help you accomplish land use change survey with lowest cost and shortest time.
