The producer’s accuracies in mapping rubber plantations and non-rubber land cover
were 87%–94% and 96%–99%, respectively, with corresponding user accuracies of 96%–99% and
88%–94%. Consequently, the overall accuracies of the resultant maps varied from 92% to 96% with
kappa coefficients from 0.84 to 0.92 (Figure 4).
