LiDAR is currently the most accurate technology for AGB estimation. LiDAR metrics can be derived from the 3D point cloud (echo-based) or from the canopy height model (CHM). Different sensors and survey configurations can affect the metrics derived from the LiDAR data. We evaluate the ability of the metrics derived from the echo-based and CHM data models to estimate AGB in three different biomes, as well as the impact of point density on the metrics derived from them %K Airborne LiDAR data %K Aboveground biomass %K Point density %K Data thinning %K Echo-based %K Canopy height model %U https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5311013/
