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.本数据集为一项基于IceBird机载激光扫描数据开展的海冰冰脊分布式提取与评估研究提供支撑。数据集包含点云数据、基于德劳内（Delaunay）算法的不规则三角网（TIN）表面、采用分布式与单机两种方法提取的冰脊线，以及包含时空匹配ICESat-2剖面的ICESat-2/机载激光扫描（ALS）冰脊峰值对比文件。数据集的结构与各文件的详细说明详见附带的README.md文档。
