As the supplementary information source of remote sensing to the research on flood and waterlogging damages, the DEM Can provides two kinds of information, that is, the background data including the elevation, the location of ground spots and the relationships between spots, the basic relationships including the elevation-area relation, the elevationvolume relation and area-volume relation, etc. By these data and relations, the information of disastrous condition can be acquired from the interpretation of remote sensing image of flooding period, which includes the inundated area, water volume, water depth, inundated time and corp damaged content, etc. In this paper, the theory and method are stated for this research.
