Comparison of classification accuracy with SVM.

	OA (OPT)	Kappa (OPT)	OA (S)	Kappa (S)	OA (M)	Kappa (M)
SVM (XZ)	83.65%	0.63	61.61%	0.31	97.30%	0.91
SVM (PV)	81.95%	0.53	73.19%	0.16	88.48%	0.75

Note. SVM (XZ): SVM classification results of Xuzhou; SVM (PV): SVM classification result of Pavia; OA (OPT/S/M): OA of optical/SAR/merged data; kappa (OPT/S/M): kappa coefficient of optical/SAR/merged data.
