Color orthomosaics of the 50-ha plot on Barro Colorado Island, Panama, for 2014-2019

3-7 cm resolution color (RGB, red-green-blue) orthomosaics of the 50-ha
Smithsonian ForestGEO plot on Barro Colorado Island, Panama, for 47 dates from
2 October 2014 to 28 November 2019.

Orthomosaics were produced from photogrammetry processing of drone-acquired
imagery using Agisoft Metashape (previously Agisoft Photoscan) software.
Orthomosaics were horizontally aligned to the first set (2 October 2014) using
the centers of Attalea palms and other tree crowns as manual control points.

Author contribution for datasets for 2014-2015: Helene C. Muller-Landau
conceived the research, wrote the grant proposal that funded the research, and
designed data collection. Jonathan Dandois constructed the drones, led drone
data collection, performed photogrammetry processing, and did preliminary
horizontal alignment. Samuel Grubinger finalized horizontal and vertical
alignment and identified canopy disturbances. Raquel F. Araujo revised canopy
disturbances and classified them as branchfalls, treefalls, or standing dead
trees.

Author contribution for datasets for 2016-2019: Helene C. Muller-Landau
conceived the research and designed the data collection. Milton Garcia led
drone data collection and processed drone imagery. Raquel F. Araujo performed
horizontal and vertical alignment, identified canopy disturbances, and
classified disturbances as branchfalls, treefalls, or standing dead trees.
