| Abstract: |
| Taking agriculture and pasturage interlaced region of Jingbian County in Shaanxi Province as a study area, the region was classified into nine categories using the hierarchical classification method. Based on the analysis of spectral characteristics of TM images, landuse categories were obtained layer by layer using model maker of ERDAS software. The results showed that, contrasted with the traditional supervised classification method, the accuracy of hierarchical c
lassification method was significantly improved, and the overall classification accuracy was 87.41%, while Kappa coefficient reached 85.53%. |
