Tropical Forest Inventory in Brazil

Geographical location of the Tapajos National Forest, PA, Brazil, outlined in yellow.

Location of the Tapajos National Forest, PA, Brazil, outlined in yellow. The gray lines are GLAS sampling flight tracks from 2003 to 2009 and the blue circles are the forest plots sampled. The pictures on the right illustrate three of the stands where plots were located (Goncalves et al., 2017).

Tree Inventory and Biometry Measurements, Tapajos National Forest, Para, Brazil, 2010

This dataset provides tree inventory, tree height, diameter at breast height (DBH), and estimated crown measurements from 30 plots located in the Tapajos National Forest, Para, Brazil collected in September 2010. The plots were located in primary forest, as well as areas of primary forest subject to reduced-impact selective logging between 1999 and 2003, and secondary forest with different age and disturbance histories. Plots were centered on GLAS (the Geoscience Laser Altimeter System) LiDAR instrument footprints selected along two sensor acquisition tracks spanning a wide range in vertical structure and aboveground biomass. The data were collected to gain a better understanding of the uncertainty associated with plot-level biomass estimates obtained specifically for the calibration of remote sensing measurements.
