Exploring trees in 3D using Terrestrial Laser Scanner

Tree form assessments using the Terrestrial Laser Scanner (TLS) have increased during recent years, but many existing methods are limited to small-sized trees. Based on the assumption that architectural trait variations influence the way a tree explores space, Lecigne et al. present an R package dedicated to derive qualitative (geometrical) and quantitative (volumetric) metrics from TLS point clouds of large trees.

Additionally, they use simulated and β€˜real world’ TLS data to demonstrate that space exploration is relevant to analyse tree architecture, and to document the effect of voxel size on tree volume estimates and occlusion compensation.
