Abstract
It is important to survey topography around debris flow precisely and speedy for disaster prevention. Aerial/ground survey has been used for such a survey. However, these method are neither sufficiently speedy nor safety. Airborne LIDAR is a new technology, which can acquire precise topography data speedy and safety. In this paper, some sample images of debris flow, those are acquired by airborne LIDAR in Kyushu district are introduced.
