3.3 Model summaries and evaluation
Descriptive statistics for each forest-type predicted tree height and
density map are presented in Table 1. The mean, maximum and minimum
values of predictions generally aligned with those of the plots. Tree
height models with the highest r2 values were
coniferous-broadleaf forest, broadleaf forest, and mangroves (Table 1)
but appeared to have the best performance for tropical dry forests as it
had relatively small RMSE and a correlation of ~0.65
(Fig 3a).
