Abstract
An object-oriented method to detect building damage is developed using high-resolution synthetic aperture radar(TerraSAR-X) data focusing on the 2011 Tohoku earthquake and tsunami event. To detect changes caused by the tsunami,damage function was developed by correlating mean value of correlation coefficient calculated based on an object-oriented method using pre- and post-event TerraSAR-X data and building damage ratio in each object. The estimated result of damage ratio showed good agreement with ground truth data,showing the pearson's correlation coefficient of 0.96. The method was verified by applying on the other test site,and the results were found consistent with the reported damage features,with correlation coefficient of 0.8.
