| Abstract: | Natural disaster is one of the major cha1lenges to the world during the Twenty-firstCentury for sustainable development of society. in this paper, the concept of Digital DisasterReduction System (DDRS) is presented. Based on the advanced computer technology and un-derstanding of natural disaster, the frame of digital disaster reduction system (DDRS) is des-cribed. DDRS is constituted by integrating of computer hardware and software, supported bythe remote sensing, global positioning system and geographic information system, web technolo-gy,viftual reality, with rational mathematical and physical models of disasters as the core ofthe system to simulate the who1e process of natural disaster. The proposed DDRS could beapplied not only for disaster prevention and reduction, but also being a powerful tool forstudy of natural disaster itself. |
