LANDSAT8衛星画像による道有林の風倒被害解析と被害把握への活用

抄録

In October 2015, Typhoon 201523 created very strong winds in central Hokkaido, Japan, causing windfall forest damage in Hokkaido prefectural forests. To assess the windfall damage quickly, we applied remote-sensing techniques using LANDSAT8 images (resolution 30 m) to estimate the distribution and area of the windfall damage and gave the results to relevant organizations. We could evaluate large-scale (≥1 ha) windfall damage, and we found that the LANDSAT8 analysis results helped to reduce the effort required in field surveys.
