An Application Guide for Generating an Enhanced Forest Inventory

Press Release – Airborne Laser Scanning (ALS) data enables the accurate three-dimensional characterization of vertical forest structure. ALS data have proven to be an information-rich asset for forest managers, enabling the generation of highly detailed digital elevation models and the … Continue reading

Impact of Lidar Pulse Density on Estimating Biomass

Airborne lidar is well-suited for mapping many forest attributes, including aboveground biomass (AGB) stocks and changes in selective logging in tropical forests. However, trade-offs still exist between lidar pulse density and accuracy of AGB estimates. This team of researchers assessed … Continue reading

Tree Segmentation

Traditional methods for segmenting trees attempt to isolate prominent tree crowns from a lidar-derived canopy height model. This group of researchers have introduced a novel segmentation method, “layer stacking,” which slices the entire forest point cloud at 1-m height intervals … Continue reading
