| Outline of Final Research Achievements |
In this research, we aimed to develop a method to extract urban areas using satellite SAR and airborne LiDAR for the purpose of extracting districts damaged by disasters. First, we developed a method to extract urban areas from satellite SAR images, that is robust to polarization orientation angle, and then proposed a method to estimate urban densities. Next, we developed a method to detect land cover changes by using polarimetric SAR images and optical images. Then, we proposed a method to automatically estimate urban landscape indices from airborne LiDAR data and images as by-product of three-dimensional building modeling. Finally, we developed a method to extract buildings damaged by disasters by using point clouds generated from aerial images.
