Data was collected across 15 plots in Wytham Woods, UK, in leaf-on and -off conditions for 3 years. For 5 of the plots all ash trees were girdled to simulate death by the fungal pathogen Hymenoscyphus fraxineus ('ash dieback'), 5 of the plots were 'ash-control' where the dominant species were Fraxinus excelsior and the remaining 5 plots were non-ash dominant. TLS data was acquired on the four edges of the plot and the plot centre. For the summer 2020 and winter 2021 acquisitions the scanner was mounted on a pneumatic mast to capture data from different heights (2 m, 4 m, and 6 m), from summer 2021 onwards the scanner was mounted at a height of 2 m. The scanner was set to an angular step of 0.04 degrees. In between each scan position a set of retro-reflective targets were positioned to be used as tie-points between scans. 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, all acquistions for the same plot were registered to the same coordinate system. For more information on TLS acquisition for this project see Wilkes et al. (2021) and more generally refer to Wilkes et al. (2017) which can be found in the documentation section.
