Building Collapse Assessment by the Use of Postearthquake Chinese VHR Airborne SAR.
IEEE Geoscience and Remote Sensing Letters(2015)
摘要
In this letter, a comprehensive study of the mapping of building collapse levels by the use of postearthquake synthetic aperture radar (SAR) images is addressed. Although previous studies have successfully quantified the collapse level by the use of postevent SAR, the types of features that are of benefit to the final accuracy still remain unknown. This letter takes the Yushu earthquake as a case ...
