Forest understory trees can be segmented accurately within sufficiently dense airborne laser scanning point clouds

17 Feb 2017 Hamid Hamraz Marco A. Contreras Jun Zhang

Airborne laser scanning (LiDAR) point clouds over large forested areas can be processed to segment individual trees and subsequently extract tree-level information. Existing segmentation procedures typically detect more than 90% of overstory trees, yet they barely detect 60% of understory trees because of the occlusion effect of higher canopy layers...
