Datasets for Extracting Arctic Sea Ice Pressure Ridges from Large-scale Airborne Laser Scanner Point Clouds

This dataset supports a study on distributed extraction and evaluation of sea-ice pressure ridges from IceBird airborne laser scanning data. It includes point cloud data, Delaunay-based TIN surfaces, ridge lines extracted using both distributed and single-machine approaches, and ICESat-2/ALS ridge-peak comparison files where spatiotemporally coincident ICESat-2 profiles are available. More details about the dataset structure and file descriptions are provided in the included README.md file.本数据集支撑一项基于IceBird机载激光扫描数据开展的海冰压力脊分布式提取与评估研究。数据集包含点云数据、基于德劳内（Delaunay）三角网的曲面、采用分布式与单机两种方法提取的海冰脊线，以及包含时空重合ICESat-2剖面数据的ICESat-2/ALS脊峰对比文件。有关数据集结构与文件说明的更多细节，请参见随附的README.md文件。
