Building Density Estimation using ALOS/PALSAR Polarimetric Data

Abstract

The latest Nankai Trough earthquake occurred in 1946, and there is 70 % probability that the next Nankai Trough earthquake will occur during the period between 2014 and 2044. In order to mitigate the damage, it is necessary to know the situation as fast as possible just after the earthquake. In this study, a method for estimating buildings density was explored using ALOS/PALSAR polalimetric data in Takamatsu.
