| Abstract: | The CBERS-02B is China's first civilian high-resolution remote sensing satellite,which starts the imagery distribution from 2007.It has been widely applied in many fields,such as the land using,urban planning,disaster prevention and mitigation.In order to promote the application of domestic satellite data,this paper chose the CBERS-02B multi-spectral and high-resolution imagery as data source and Fuling district in Chongqing as experimental area,and studied both extraction method of land use/land coverage information and characteristics of different surface objects.This paper also studied the applied problems of CBERS-02B data.In the study,hierarchical method,using DEM and NDVI data as supplements was applied in the classification.The result indicated that the CBERS-02B data could basically meet the requirement of land use macro-monitoring in complex region. |
