Abstract: A fully automated approach for detecting land use/cover change using remote sensing data, GIS data, GPS data is presented. The integrating raster with vector methods of updating the basic land use/land cover map based on 3S technology is becoming one of the most important developing directions in 3S application fields, land-use and cover change fields over the world. It has been successful applied in two tasks of the Ministry of Land and Resources of China, and takes some benefit.
Key words: 3S technology； land-use and cover change； object-oriented
