Cover Story: In the last two decades, unmanned aircraft systems (UAS) have successfully been used in different environments for diverse applications. For UAS LiDAR-based mapping missions, the requirements for flight planning differ from those of conventional UAS image-based flight plans because of various reasons related to the LiDAR scanning mechanism, scanning range, output scanning rate, field of view (FOV), and rotation speed, amongst others. The article presents flight planning simulations in which the UAS platform is equipped or, alternatively, three low-cost multi-beam LiDARs, namely Quanergy M8, Velodyne VLP-16, and Ouster OS-1-16. The specific characteristics of the three sensors were used to plan flights and acquire dense point clouds. The results show clear relationships between point density, flying speeds, and flying heights. View this paper
