Set of DEM models from a section of the dune coast in Mrzeżyno (Poland) - demo data for testing in the CMORPH application.

This dataset contains five folders with DEM models created from UAV LiDAR point cloud collected along the coastline of Mrzeżyno, Poland.The data were acquired using a DJI Zenmuse L1 and L2 sensors mounted on an UAV platform (DJI Matrice 300 and DJI Matrice 350).These files are intended for the analysis of morphological parameters of the dune coast and can be used to test the CMORPH application. Acquisition dates:2021-02-242022-02-282023-02-282024-02-132024-05-29 Coordinate system:EPSG:2180 (ETRS89 / Poland CS92) Sensors:DJI Zenmuse L1 (UAV LiDAR)DJI Zenmuse L2 (UAV LiDAR) Notes:The dataset can be used to determine the shoreline, base and crest of the dune, slope, volume and width using the CMORPH application. Folders structure:YYYY-MM|- input|--- coast |---- trans-lline.SHP (includes a line for generating cross sections)|---- crop |---- clip.SHP (includes a mask)|---- dem |---- YYYY-MM-DD.TIF (includes a digital elevation model) After downloading unzip all files.It is important to keep all files and folder structures intact for CMORPH to work properly.本数据集包含5个文件夹，其内存储了基于沿波兰姆热日诺海岸线采集的无人机激光雷达（Unmanned Aerial Vehicle LiDAR, UAV LiDAR）点云数据生成的数字高程模型（Digital Elevation Model, DEM）。数据采用搭载于DJI Matrice 300与DJI Matrice 350无人机平台的DJI Zenmuse L1和L2传感器采集获取。本数据集可用于沙丘海岸形态参数分析，同时可用于CMORPH应用程序的测试验证。 采集日期：2021-02-24、2022-02-28、2023-02-28、2024-02-13、2024-05-29 坐标系：EPSG:2180（ETRS89 / 波兰国家坐标系CS92） 传感器：DJI Zenmuse L1（无人机激光雷达）、DJI Zenmuse L2（无人机激光雷达） 备注：本数据集可通过CMORPH应用程序，实现海岸线、沙丘基底与丘顶、坡度、体积及宽度的提取计算。 文件夹结构：YYYY-MM |-- input |-- coast |-- trans-lline.SHP（包含用于生成断面的线要素） |-- crop |-- clip.SHP（包含掩膜文件） |-- dem |-- YYYY-MM-DD.TIF（包含数字高程模型） 下载完成后请解压所有文件，为确保CMORPH应用程序正常运行，请保留完整的文件与文件夹结构。
