This dataset contains three UAV LiDAR point cloud files (.las format) collected along the coastline of Mrzeżyno, Poland.The data were acquired using a DJI Zenmuse L1 sensor mounted on an UAV platform (DJI Matrice 300).These files are intended for shoreline detection and coastal monitoring applications, and can be directly used with the S-LiNE Toolbox.
