Terrestrial, UAV-borne, and airborne laser scanning point clouds of central European forest plots, Germany, with extracted individual trees and manual forest inventory measurements

Laser scanning point clouds of forest stands were acquired in southwest Germany in 2019 and 2020 from different platforms: an aircraft, an uncrewed aerial vehicle (UAV) and a ground-based tripod. The UAV-borne and airborne laser scanning campaigns cover twelve forest plots of approximately 1 ha. The plots are located in mixed central European forests close to Bretten and Karlsruhe, in the federal state of Baden-Württemberg, Germany. Terrestrial laser scanning was performed in selected locations within the twelve forest plots. Airborne and terrestrial laser scanning point clouds were acquired under leaf-on conditions, UAV-borne laser scans were acquired both under leaf-on and later under leaf-off conditions. In addition to the laser scanning campaigns, forest inventory tree properties (species, height, diameter at breast height, crown base height, crown diameter) were measured in-situ during summer 2019 in six of the twelve 1-ha plots.

2019年至2020年，在德国西南部，通过不同平台（包括飞机、无人机及地面三脚架）获取了森林群落的激光扫描点云数据。无人机搭载及航空激光扫描行动覆盖了约1公顷的十二个森林样地。这些样地位于德国巴登-符腾堡州布莱滕和卡尔斯鲁厄附近的混交中欧森林中。在十二个森林样地中选定位置进行了地面激光扫描。在叶茂期条件下获取了航空和地面激光扫描点云，无人机搭载激光扫描在叶茂期及后续的落叶期条件下均进行了采集。此外，在2019年夏季，对十二个1公顷样地中的六个进行了现场测量，以获取森林清查树木属性（物种、树高、胸径、冠基高、冠径）。
