Dataset
Forest Degradation Experiment (FODEX), Ogooué-Ivindo (FGC-04), Gabon, pre-logging, January 2020
Abstract
This dataset is comprised of raw data from the EC-funded FODEX project to collect full waveform terrestrial laser scanner (TLS). Plots were scanned prior to and following logging at different intensities to quantify the impact of logging intensity on rate of recovery of carbon stocks. Plots FGC-04 is located in Ogooué-Ivindo, Gabon and owned and managed by commercial logging company Rougier Ivindo.
TLS data was collected on a 10 m x 10 m grid where at each position the scanner captured data in an upright and tilted position. The scanner was set to an angular step of 0.04 degrees and 0.02 degrees for upright and tilted scans respectively. In between each scan position a set of retro-reflective targets were positioned to be used as tie-points between scans. For more information on TLS acquisition refer to Wilkes et al. (2017). Scan data was coregistered using RiSCAN Pro, the 4x4 rotation transformation matrices to transform the point cloud data into a common reference coordinate system can be found in the "matrix" directory.
