【Abstract】 Based on GIS and system integration technology, the automatic mapping of river terrain, the spatio temporal management of terrain information, the 3D terrain expression, and the deposition scouring analysis for any time interval and any location are realized, and a river terrain information system of specialistic treatment and analysis is formed. The new concept of river digital terrain information system is proposed for the research of digital technology applied to riverbed evolution and river channel regulation.更多还原
