DMSP夜間可視画像を用いた広域都市圏の同定と地震被害ポテンシャルの推定

抄録

We propose a method to identify metropolitan area cluster which could be a reasonable unit to prepare and response against future earthquake disaster. A method to estimate the distribution of population and number of buildings in 1Km-mesh using DMSP/OLS (Defense Meteorological Satellite Program/ Optical Linescan System) night-time imagery which capture city lights reflecting extent of human activity is also proposed and its application limit is examined.
