Handheld laser scanning point clouds collected in spring 2020 from 8 plots in Evo, Finland.

Handheld laser scanning point clouds collected in spring 2020 from 8 plots in Evo, Finland. The data was collected with a Zeb Horizon (GeoSLAM, UK) handheld laser scanner and processed with GeoSLAM hub software with forest SLAM and loop closures enabled. The point clouds are in scanner coordinates, and scan trajectories are provided in the "Trajectories" folder. The plot numbering is consistent with the other point clouds available through the SCANFOREST research infrastructure. (https://www.scanforest.fi/data/) The tree attributes were calculated from this data in Muhojoki J., et al. (2024) Benchmarking Under- and Above-canopy Laser Scanning Solutions for Deriving Stem Curve and Volume in Easy and Difficult Boreal Forest Conditions.

2020年春季于芬兰埃沃（Evo）地区的8块样地采集的手持激光扫描点云数据。本数据集由英国GeoSLAM公司的Zeb Horizon手持激光扫描仪完成采集，并通过GeoSLAM Hub软件进行处理，处理过程中启用了森林同步定位与建图（Forest SLAM）与回环闭合（loop closures）功能。该点云数据采用扫描仪坐标系，扫描轨迹文件存储于"Trajectories"文件夹中。样地编号与SCANFOREST研究基础设施提供的其他点云数据保持一致，相关数据可通过https://www.scanforest.fi/data/获取。树木属性参数由Muhojoki J.等人于2024年在《针对难易北方针叶林环境下树干曲线与材积估算的冠层上下激光扫描方案基准测试》（Benchmarking Under- and Above-canopy Laser Scanning Solutions for Deriving Stem Curve and Volume in Easy and Difficult Boreal Forest Conditions）一文中基于本数据集计算得出。
