Boxplots of the differences in mean height and FC for each study site and plot size. The reference data for the comparison were the original point density and the plot size used for field measurements. Left column Sierra Nevada Mountains; central column Barro Colorado Island; right column Serra do Mar. Top row Echo-based mean canopy height; second row CHM-based mean canopy height; third row Echo-based FC; bottom row CHM-based FC
