In the summer of 1991, the region of Yangtze and Huaihe river suffered a catastrophic flood disaster, TMimages provide rich information of flood scope, surface moisture and vegetation growing, on which crop harvest depends. Through numerical analysis and applied processing of TMimage acquired on July, 14, five days after flood peak, the components humidity(H) Greenness (G)and other now indices were obtained. After a new supervised classification a map with heavy, moderate, light degree of disaster, undamaged region and residential spots was achieved as well as each class area. checking in the field indicated that the result was accurate.
