 This research paper examines the use of unmanned aerial vehicle UAV technology to create detailed point clouds from aerial photographs taken at a natural coastal site in southeastern Tasmania, Australia. The resulting point clouds were then compared to ground truth data gathered by a total station survey to determine the accuracy of the point cloud data. The authors found that the point clouds were accurate to within 25 to 40 millimeters, which was sufficient to detect changes in the terrain caused by coastal erosion.
