摘要：The purpose of this project is the flood disaster prevention. Recently it has been happened frequent floods in the small and middle size rivers caused of the local heavy rainfalls in Japan. The Japanese River Bureau had decided to the achievement project what the terrain of river channel and flood plain terrain would be gotten by Airborne Laser terrain mapping (Lidar). Next consideration, we would try the measurement of the tree assemblage's coverage in river channel. The tree assemblages sometimes prevent water from flowing and some flood disasters happen. We would consider about "the woodiness rate" the relative correlation between the field plant survey data and the laser point cloud data. This paper is introduced how to calculate the woodiness rate using the laser point clouds
