Multi-modal close-range laser scanning individual tree point clouds for tree age prediction (n = 339) at the Evo test site (May-June 2023)

Close-range terrestrial and airborne laser scanning point clouds extracted for individual trees (n = 339) along with increment borer-derived observations of tree age at the breast height. The data was acquired from the Evo test site during May-June 2023 using a Leica RTC360 terrestrial laser scanner and a helicopter-borne three-sensor ALS system at a low altitude for dense point cloud data acquisition.

本数据集涵盖339棵单木的近程地面激光扫描与机载激光扫描点云数据，以及通过生长锥（increment borer）测得的单木胸高树龄观测结果。该数据集于2023年5月至6月期间在Evo测试场采集，采集过程中使用徕卡RTC360地面激光扫描仪，搭配直升机搭载的三传感器机载激光扫描（airborne laser scanning, ALS）系统，以低空作业模式完成高密度点云数据的获取。
