Coastal Activity Risk Assessment using Aviation Images and Hyperspectral Images

Abstract

Coastal activities cause an increasing number of human casualties. This study purpose of assessing coastal activity risk by selecting and quantifying physical elements using remote sensing data such as aviation- and hyperspectral images. For tidal flat and breakwater, aviation images were used to categorize sediments and calculate the hole between tetrapods, respectively. For breakwater and seashore rocks, hyperspectral images were used to compute the ratio of moss.
