Terrestrial LiDAR data from the SCATTER project

The Scanning Ancient Trees with Terrestrial LiDAR (SCATTER) project captured ancient oak trees with terrestrial LiDAR across the UK to characterise and compare tree architecture. SCATTER was funded by the Woodland Trust and led by UCL. Method Trees were scanned in between April 2021 and April 2024 at locations across the UK (click on ATI numbers to see location). Scans were acquired with a RIEGL VZ400i terrestrial LiDAR where scan pulse rate was set to 600 KHz and angular resolution set to 0.04 degrees. Between 6 and 12 scan locations were used to capture each tree, depending on tree size and access. Individual scans were then merged and the resulting point cloud subsampled using a voxel size of 0.01 m. Point clouds are stored in Polygon format and can be viewed in software such as CloudCompare. Each file contains a point cloud with the following fields. Field Property x, y, z 3D coordinates nx, ny, nz psuedo-normal that shows direction to scan position reflectance normalised reflectance values deviation deviation from sp scan position number label 0=surroundings, 1=tree, 2=supports Licence and usage This research was funded by the Woodland Trust Conservation Research Programme.
