摘要：Japan is one of the most earthquake-prone countries in the world and also faces frequent typhoons, severe rain storms and sediment - related disasters. Despite those frequent natural disasters, it is difficult to determine the extent of the disaster damage rapidly and extensively. Considering such problems, it was greatly realized to develop highly effective usages of spaceborne and airborne sensing technology. Currently, we are developing a disaster information service based on satellite and airborne sensors. In the proposed system, Synthetic Aperture Radar (SAR) satellite sensor acquires images of the areas of interest during normal phase, and archived as ready-to-use reference data. After the occurrence of a disaster the quickest way of data acquisition is possible by utilizing satellite or airplane sensors. In case of SAR satellite, it is possible to extract changed areas between images acquired before and after the disaster. If more detailed information is required, images acquired by airborne sensors are analyzed for mapping disaster-affected areas and can be provided to the decision makers. Moreover, acquiring images regularly after disaster, it is possible to monitor recovery and restoration status of the damaged areas
