| Outline of Final Research Achievements |
Synthetic Aperture Radar (SAR) has a scheme to emit microwaves to the earth surface and then observes the reflected echoes. SAR sensors onboard satellites or aircraft can be used day-time and night-time and in all weather conditions. In this research, damage detection of man-made structures and extraction of flooded/landslide areas due to natural disasters were carried out using post-event high-resolution SAR images and pre-event optical images and GIS data. Building damage due to the 2016 Kumamoto earthquake, flooding areas due to the 2018 Western Japan torrential rain and the 2019 Typhoon Hagibis, landslides due to the 2018 Hokkaido-Eastern-Iburi earthquake were extracted successfully using satellite SAR data. But the necessity of pre-event SAR data or land-cover and GIS data is suggested to avoid false extraction.
