Abstract: In this paper, the research scheme of flood and waterlogging damage is suggested by using remote sensing and geographical information system, and its contents are as following:(1)evaluation of the resources and the information processing; (2) analysis on mechanism and loss of the damage;(3) forecast of the damage and strategic decision for prevention and cure of the damage. In this scheme, the basic functions of technical system are:(I)image and data handling;(2) extraction and analysis of the basic information; (3) loss analysis model and forecast model. As a part of this study, a series of our experiments are also introduced.
