Test data for 'High-resolution topographic surveying and change detection with the iPhone LiDAR'

The data includes several iPhone LiDAR scans from a coastal cliff with a melting ice-food in the town of Longyearbyen on Svalbard recorded on June 15 and 24, 2023. The different 3D models overlap and can be combined into one large file or treated separately as smaller files. Change can be calculated between scans of the same area, especially focusing on the melt of the ice-foot in between the two recoding dates.Each LiDAR scan is provided in three different data formats: (i) a textured, triangulated mesh, (ii) a geo-referenced LAS point cloud with coordinates in Lat. and Long. and (iii) a geo-referenced LAZ point cloud with coordinates in meters.The data is intended as a test dataset for the protocol paper 'High-resolution topographic surveying and change detection with the iPhone LiDAR.'

本数据集包含2023年6月15日与24日，在斯瓦尔巴群岛（Svalbard）朗伊尔城（Longyearbyen）某沿海悬崖采集的多组iPhone激光雷达（LiDAR）扫描数据，扫描区域内存在正在消融的冰脚（ice-foot）。各三维模型间存在空间重叠，既可以合并为单个完整的大型文件，也可拆分为多个小型文件单独处理。可通过对同一区域的多次扫描结果计算地表变化，尤其聚焦于两次采集时段间冰脚的消融过程。每份激光雷达扫描数据均提供三种数据格式：(i) 带纹理的三角网格模型；(ii) 采用经纬度坐标的地理参考LAS点云；(iii) 以米为单位的地理参考LAZ点云。本数据集专为配套规程论文《基于iPhone激光雷达的高分辨率地形测量与变化检测》（DOI: 10.1038/s41596-024-01024-9）提供测试使用。
