The purpose of the study is to evaluate CBERS-02B data quality.Methods of qualitative and quantitative analysis were employed.The results indicate that,the position error of HR data after geo-rectification is about 8-11m.The attribute accuracy for construction land,cultivated land and newly-increased construction land is about 80% while the average relative area error of extracted change plots is about 10%.It is concluded that CCD data of CBERS-02B can be used to monitor land dynamic change at macro scale of 1:100,000.HR and CCD fused image can be used to monitor land dynamic change at small or medium scale if the data acquisition capacity is not considered.
