With the increase in natural disasters in Japan, the large amount of driftwood has a severe impact on the marine industry and environment. The Asia Air Survey Co., Ltd. conducts the aerial survey immediately after a disaster occurs and provides open data images of the damaged sites on the website. In this survey, the “driftwood map" was made to assess the distribution and quantity of driftwood, using the oblique photography from 2020 Kyusyu flooding.
