UAV laser scanning and terrestrial laser scanning point clouds of snow-on and snow-off conditions of a forest plot in the black forest at Hundseck, Baden-Württemberg, Germany [data]

This dataset consists of 3D point clouds acquired via UAV laser scanning (ULS) of a forest plot in the Black Forest in Hundseck, Germany. The plot was captured under snow conditions in January 2021, and the acquisition was repeated under snow-off conditions in February 2021. Additional terrestrial laser scanning (TLS) point clouds were acquired as reference. Details about the acquisition and preprocessing are described in the documentation. The data can be used to assess snow depths in the observation period, as well as the topography and vegetation structure.

本数据集包含德国洪泽克（Hundseck）黑森林内某森林样地通过无人机激光扫描（UAV Laser Scanning, ULS）获取的三维点云数据。该样地于2021年1月在积雪覆盖条件下完成首次数据采集，并于2021年2月在无积雪条件下重复开展采集工作；此外还采集了地面激光扫描（Terrestrial Laser Scanning, TLS）点云数据作为参考基准。有关数据采集与预处理的详细说明已收录于配套文档中，本数据集可用于评估观测周期内的积雪深度，同时也可用于分析地形与植被结构。
