抄録

By the typhoon 9119, a large number of trees was felled and broken in the forest around Hita city. In this study, the damaged forest area was extracted using satellite data. First, the sunny and the shady parts of the forest were identified using the satellite data obtained before the typhoon. By applying the data to the data after typhoon and treated using RVI and NDVI, the area of the felled and broken trees were identified. The obtained results showed the same accuracy as the data examined manually in mesh divided areas. It was shown that the analysing method using the remote sensing data can offer the simultaneous data over wide area where data are hard to obtain.
