Extended Data Fig. 5: Tree crown model evaluation at plot level.
From: Nation-wide mapping of tree-level aboveground carbon stocks in Rwanda
We manually labelled 6,591 trees and compared predictions and labelled trees at plot level. a, Tree density, b, canopy area, c, mean crown size. Each point represents one 25×25 m grid, n = 153. The bias was calculated following equation (2). d, Density distribution of the crown areas in the training and test dataset.
