| Abstract: | New technologies promise reduced flood losses. However, real-time observations with vast multi-sensor networks, more precise mapping capabilities using remote sensing and GIS, quicker hydrological and meteorological models, and increasing forecast lead times have not yet resulted in reduction of losses. In this paper, the author discusses the applications of remote sensing and GIS in combating floods and conducting loss evaluation and presents the design principle of flood pre-warning monitoring and loss evaluating system. The system function modules were designed according to object-oriented theory, so as to realize the data managing, image processing, spatial analysis and output simulating function. |
