Research using ground-based LiDAR for precision tree structure characterization and analytical framework to assess quality and health of hardwoods using LiDAR data.

lidar tree health scan 3D point cloud composed of 12 million individual data points acquired with a single scan using terrestrial LiDAR system (TLS) in the center of a mixed species planted stand at Martell Forest. Warmer colors correspond to taller portions of the canopy.
