Paper Abstract

As the second Chinese civilian high spatial resolution satellite, the ZY-02C satellite was successfully launched on December 22, 2011. In this paper, we used two different methods, subjective evaluation and external evaluation, to evaluate radiation quality of ZY-02C panchromatic image, meanwhile, we compared with quality of CBERS-02B, SPOT-5 satellite. The external evaluation could give us quantitative image quality. The EIFOV of ZY-02C, one of parameters, is less than SPOT-5. The results demonstrate the spatial resolution of ZY-02C is greater than SPOT-5. The subjective results show that the quality of SPOT-5 is little preferable to ZY-02C,CBERS-02B, and the quality of ZY-02C is better than CBERS-02B for most land-cover types. The results in the subjective evaluation and the external evaluation show the excellent agreement. Therefore the comprehensive result of the image quality will be got based on combining parameters introduced in this paper.
