45 Introduction Light Detection and Ranging (LiDAR) is a remote sensing tool that can potentially be used to conduct timber inventories. LiDAR has been used for the quantification of biomass, tree and stand height, and basal area estimation (Nelson et al.he LiDAR inventory costs included the cost of obtaining the LiDAR data, the ground plots for determining the height volume relationship, and LiDAR data processing. If LiDAR data are already available, the cost of extracting the plots and processing the data for timber inventory is very low.
