ForestScan Project: Unpiloted Aerial Vehicle LiDAR Scanning (UAV-LS) and Terrestrial Laser Scanning (TLS) data of FBRMS-01: Paracou, French Guiana plot 6, 10th October to 15th November 2019

This dataset contains LiDAR scanning derived products (raw scanner data, geo-located point clouds, individual 3D tree models) collected over the north-eastern part (200 m x 200 m) of FBRMS-01: Paracou, French Guiana plot 6. The campaign took place from the 10th of October to the 15th of November 2019. Terrestrial LiDAR Scanning (TLS) was conducted on a regular grid with spacing of 10 m with a RIEGL VZ-400 scanner and retro-reflective targets for scan registration. Unpiloted Aerial Vehicle Laser Scanning (UAV-LS) was conducted with a RIEGL Ricopter with VUX-SYS VUX-1UAV system with varying flight heights and flight directions.

The TLS point clouds were collected to produce explicit 3D models of individual trees and subsequently estimate their above-ground biomass (AGB). The UAV-LS point clouds were collected to test scanner settings and inspect point clouds properties, in particular with regard to their suitability to model individual trees and their AGB.

The campaign was conducted by researchers Benjamin Brede, Harm Bartholomeus and Alvaro Lau of the Laboratory of Geo-Information Science and Remote Sensing of Wageningen University & Research (The Netherlands) with support from Nicolas Barbier of AMAP Lab (Botany and Modeling of Plant Architecture and Vegetation).

该数据集包含基于激光雷达（LiDAR）扫描的衍生产品（原始扫描数据、地理定位点云、单棵树木三维模型），采集于法属圭亚那Paracou地区FBRMS-01样地6的东北部区域（200米×200米）。数据采集活动于2019年10月10日至11月15日开展。

地面激光雷达扫描（Terrestrial LiDAR Scanning，TLS）采用RIEGL VZ-400扫描仪，在间距为10米的规则网格上进行，并使用回射靶标完成扫描配准。无人机激光扫描（Unpiloted Aerial Vehicle Laser Scanning，UAV-LS）通过搭载VUX-SYS VUX-1UAV系统的RIEGL Ricopter无人机开展，飞行高度与方向均有所变化。

采集TLS点云旨在生成单棵树木的清晰三维模型，进而估算其地上生物量（Above-ground Biomass，AGB）。采集UAV-LS点云则用于测试扫描仪设置及考察点云特性，尤其关注其在单棵树木建模及AGB估算中的适用性。

该活动由荷兰瓦赫宁根大学及研究中心（Wageningen University & Research）地理信息科学与遥感实验室的Benjamin Brede、Harm Bartholomeus和Alvaro Lau研究员主导，并得到了AMAP实验室（植物建筑学与植被建模实验室，Botany and Modeling of Plant Architecture and Vegetation）Nicolas Barbier的支持。
