Abstract EN
Light Detection and Ranging (LiDAR) data at 0.5–2 m postings were used with double-sample, stratified procedures involving single-tree relationships in mixed, and single species stands to yield sampling errors ranging from ±2.1% to ±11.5%.
LiDAR samples were selected with focal filter procedures and heights computed from interpolated canopy and DEM surfaces.
Tree dbh and height data were obtained at various ratios of LiDAR, ground samples for DGPS located ground plots.
Dbh-height and ground-LiDAR height models were used to predict dbh and compute Phase 2 estimates of basal area and volume.
Phase 1 estimates were computed using the species probability distribution from ground plots in each strata.
Phase 2 estimates were computed by randomly assigning LiDAR heights to species groups using a Monte Carlo simulation for each ground plot.
There was no statistical difference between volume estimates from 0.5 m and 1 m LiDAR densities.
Volume estimates from single-phase LiDAR procedures utilizing existing tree attributes and height bias relationships were obtained with sampling errors of 1.8% to 5.5%.
