Monitoring changes in the beach morphology of coastal landforms is important when considering coastal management measures. In this paper, to create a changing beach surface, point cloud data of the beach are obtained using three-dimensional (3D) terrestrial laser scanning (TLS), and a beach surface model is analysed based on 3D point data. The 3D point cloud is generated from the scanned beach, including breakwaters, and these points are registered and merged through a reference point (scan origin and ball target) surveyed by RTK-GPS. Noise elements and unnecessary points are eliminated to yield better surface modelli...
