Example of lidar-derived metric products of canopy structure. A) Image showing an area characterized by varied forest strands. (Red box shows from where profile data in E area taken.) B) Lidar-derived maximum canopy height. C) Lidar-derived height of low- to medium-height vegetation beneath the overstory canopy.
