Disaster Damage Detection and Its Recovery Support System of Road and Railroad Using Satellite Images
نویسندگان
چکیده
This paper describes a decision support system based on GIS and satellite remote sensing analysis. Damage triggered by the 2004 Niigata-ken Chuetsu Earthquake was detected using NDVI from SPOT images and texture analysis. Then the emergency transportation route was selected by a cost-based GIS analysis. As the result of the analysis, large-scale damage could be detected with high accuracy. From this information, two types of emergency transportation routes, roads and railways, were identified and evaluated. These results also contribute knowledge for reference in decision making for both recovery support and prevention of secondary disaster.

Cloud segmentation is a critical pre-processing step for any multi-spectral satellite image application. In particular, disaster-related applications e.g., flood monitoring or rapid damage mapping, which are highly time and data-critical, require methods that produce accurate cloud masks in a short time while being able to adapt to large variations in the target domain (induced by atmospheric c...
