| Research Abstract |
In this research, the extraction of damaged areas using high-resolution optical satellite images and Synthetic Aperture Radar (SAR) data was investigated. Assuming the existence of optical and SAR images and a digital elevation model (DEM) in the pre-event stage, and that satellite SAR data is acquired in the post-event stage, the damages due to disasters are extracted for the 2009 L'Aquila, Italy earthquake, the 2010 Haiti earthquake, and the 2011 Tohoku, Japan earthquake. Comparing with ground truth data, the accuracy of damage extraction from the SAR data was examined.
