Bridging Individual-Tree and Stand-Scale Aboveground Biomass Estimation for Chinese Fir Using LiDAR and Machine Learning
The accurate estimation of forest aboveground biomass (AGB) typically relies on extensive field surveys, which are highly time-consuming and cost-prohibitive. While unmanned aerial vehicle (UAV) Light Detection and Ranging (LiDAR) provides ultra-high point densities capable of reliable individual-tree analysis, its lim...
