Estimation of tropical forest structural characteristics, using large-footprint lidar
, 2002 Quantification of forest structure is important for developing a better understanding of how forest ecosystems function. Additionally, estimation of forest structural attributes, such as aboveground biomass (AGBM), is an important step in identifying the

Influence of footprint size and geolocation error on the precision of forest biomass estimates from space-borne waveform LiDAR [PDF]
, 2017 Space-borne LiDAR systems can potentially assist large-area assessments of forest resources, in particular when a subset of the acquired LiDAR footprints is combined with field surveys of forest stand characteristics at footprint location. When combined,
