Study on the Extraction of Remote Sensing Information of Land Use/Cover Based on Optimum Band Combination

LI Xie-hui et al(Research Center of Yellow River Civilization and Sustainable Development,Henan University,Kaifeng,Henan 475001)  
Taking the catchment area along Weihe River in Shaanxi Province as a study area,by analyzing spectral characteristics of every band,correlation coefficient matrix among bands,optimum index,revised vegetation index and principal components transformation on ETM+ image in 2002,optimum band combinations were fixed on PC1,RNDVI and Band4.After classified to study area on land use and cover using unsupervised and supervised classification,the total accuracy of classification was 90.098 7%,and the Kappa coefficient was 0.884 5.The results show that the method not only gets higher accuracy,but has simpler steps and stronger practicability,and can extract furthest remotely-sensed classified information.
