LIDAR-based estimation of bole biomass for precision management of an Amazonian...
Figueiredo, Evandro Orfanó; D'Oliveira, Marcus Vinício Neves; Braz, Evaldo Muñeoz; Papa, Daniel de Almeida; Fearnside, Philip MartinBased on airborne LIDAR data on canopy morphology and height of Amazon forest trees, we developed allometric models to estimate dry biomass stored in the boles of dominant and co-dominant individuals and compared these results with those from equations based on traditional variables such as diameter at breast height (DBH). The database consisted of 142 trees of interest for logging in a forest under management ...

Almeida, Danilo Roberti Alves de; Stark, Scott C.; Shao, Gang; Schietti, Juliana; Nelson, Bruce Walker; Silva, Carlos Alberto; Görgens, Eric BastosAirborne Laser Scanning (ALS) has been considered as a primary source to model the structure and function of a forest canopy through the indicators leaf area index (LAI) and vertical canopy profiles of leaf area density (LAD). However, little is known about the effects of the laser pulse density and the grain size (horizontal binning resolution) of the laser point cloud on the estimation of LAD profiles and the...
