Geomorphological research using unmanned aerial vehicles (UAVs) has been rapidly gaining traction recently. In this paper, we introduce UAV remote sensing using a hyperspectral camera. As is widely known, aerial photography using UAVs can acquire images with high spatial resolution. By mounting a hyperspectral camera on UAVs, it is possible to acquire images with high spectral resolution and this enables detailed spatial distribution analysis. We have considered samples of mineral distribution in river sediments and this technique may be useful for all geomorphological studies.
