3S technology, which is rooted in computer science of Remote Sensing (RS), Global Positioning System (GPS) and Geographic Information System (GIS), has been used in land and resources management, urban planning, landscape construction, and so on[1]. In the second round updating investigation of land survey in china, RS image interpretation technique has been widely useed to obtain the land use data and predict land-use information.
