Updating Categorical Soil Maps Using Limited Survey Data by Bayesian Markov Chain Cosimulation

Table 2

Percentages of correctly classified locations (PCCs) of optimal prediction maps and simulated realizations (averaged from 100 realizations) generated by Co-MCSS and MCSS. PCCs (%) are estimated relative to the reference soil map with sample data being excluded.

Item	Accuracy
	Optimal prediction map	Realization maps
MCSS	82.50	79.32
Co-MCSS	98.25	97.23
Absolute improvement^†	15.75	17.91
Relative improvement^‡	19.09	22.58

†Absolute improvement = PCC of Co-MCSS − PCC of MCSS. ^‡Relative improvement = absolute improvement/PCC of MCSS × 100.
