Primary Studies of Flood and Waterlogging Damages Using Remote Sensing in Jianghan plain

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.
