[ABSTRACT ]

Tree height is an important variable to use for calculating biomass sequestration. This study aims to compare the level of the tree height measurement method in different family forest plots. Using canopy height models in comparison with the results from the field surveys, it was found that in both experimental plots, the RMSE was 2.740 and 2.863 meters. The MAE was 2.654 and 2.666 meters. The comparison of both methods using the correlation, resulting in an R-value of 0.758 for Experimental Plot 1 and 0.993 for Experimental Plot 2. This suggestion is useful for measuring tree height in large plots.
