We have pioneered research on geospatial information system for national water census and its appl ication.Aiming to the main issues such as information obtaining,data management,qual ity control, and project organization,the overal l thought is given.It is based on taking fundamental data as supporting and data model as precursor,and viewing intel l igent tool as protective role,and combing the management theory with technical methods.The key techniques developed include the digital basin extraction,data model ing orienting to the object of water resources,data acquisition and processing within certain rules and the appl ication of multidimensional theme.
