Abstract
An object-oriented method to estimate building damage is developed using Advanced Land Observing Satellite/Phased Array Type L-band Synthetic Aperture Radar (PALSAR) data from Japan Aerospace Agency (JAXA), by focusing on the 2011 Tohoku earthquake and tsunami event. The building damage was estimated by applying the developed damage function showing a relationship between the correlation coefficient values of pre- and post-event SAR data and the damage ratio of washed-away buildings. The result was verified by the actual number of washed-away buildings, and offered the good accuracy with pearson's correlation coefficient of 0.97.
