Figure 1: This study was conducted in a ForestGEO MegaPlot (outlined in red) in the Prospect Hill Tract (inset) of the Harvard Forest, in Petersham, Massachusetts, USA
Figure 2: Manual crown delineation was performed using high resolution UAV imagery. All delineations were done on the September 13th image (left panel), but other dates of imagery were used to help differentiate crowns growing in close proximity
Table 1: Five automated LiDAR-based individual tree crown delineation routines were evaluated in this study
Figure 3: Automated crown delineations (AITC; shown with bold outline) were assessed against manual crown delineations (MITC; shown with green fill) and assigned into one of four categories based on overlapping area: a) Over-segmentation: The intersecting
