| Research Abstract |
It is required to detect quickly the damages of roads induced by earthquake when the earthquake disaster extends in a wide area。For this purpose the satellite image analysis for the detection of the damaged roads in the wide area is effective。In this study satellite image analysis of the optical sensor data and synthetic aperture radar data for detection of earthquake disaster is developed and the proposed method is applied for the case of the 2004 Chuetu earthquake in Japan。It is found that the severely damaged roads are detected by the proposed method with high accuracy。Based on the obtained digital map of the damaged roads, a useful supporting GIS system for decision of emergency retrofit of the roads has been developed。
