The aim of this study is to confirm the measurement accuracy and measurement characteristics of Green LiDAR Drone.

In Japan, due to recent climate change, the frequency of heavy rainfall has been increasing, and more floods than estimated are occurring every year. Infrastructures that can safely drain the flood are river channel and river levee. Their role is becoming increasingly important. To reduce river disasters and manage disaster risk areas, river management administrations of Japan must understand the state of river channel and river levees. In order to fully identify risk area of disaster, it is considered using Green LiDAR Drone in Japanese river management. From these backgrounds, it is necessary to clarify the measurement accuracy and measurement characteristics of Green LiDAR Drone. Therefore, in this study, we confirmed the theoretical basic performance assumed from the device performance. Also, we conducted experimental measurements on flat ground area, river area, and coast area. Through verification of experimental measurements, we confirmed the positional accuracy, bathymetric capabilities of water area, and measurement characteristics of point cloud obtained by Green LiDAR Drone. As the result, it was confirmed the point cloud acquired by Green LiDAR Drone could understand not only the riverbed or coasts topography but also the structures of rivers and coasts, and could be used as basic information for maintenance and construction.
