15WCEE | Damage Detection of the 2011 Tohoku, Japan Earthquale from High-resolution SAR Intensity Images [PDF]

Submitted by RIJS on
Item Description

The Tohoku earthquake of March 11, 2011, caused gigantic tsunamis and widespread devastation. Various high-resolution satellites quickly captured the details of affected areas, and were used for emergency response. In this study, high-resolution pre- and post-event TerraSAR-X intensity images were used to identify damaged buildings. Since the damaged buildings show changes in backscatter intensity, they can be detected by calculating the difference and correlation coefficient. A GIS map was intr
