摘要
CBERS-CCD数据波段间是否配准,尤其是第5波段与其它波段间是否存在空间位移,相关研究还少见报道。通过科研项目支助实验研究,得到①CBERS-1 CCD原始数据第5波段相同地物特征点相对其它波段向南移动0.84km,向东移动0.83km;②CBERS-2CCD原始数据第5波段相同地物特征点相对其它波段向南移动0.74km,向东移动0.11km;③利用CBERS-CCD数据开展应用项目研究,尤其是用到第5波段数据时候,必须重视波段间客观存在空间位移问题。
There had no report about spatial displacement of CBERS - CCD data, especially about its band - 5. With the support of an experimental project, this paper makes some conduct that： （ 1 ） CBERS - 1 CCD band -5 had moved 0. 84kin towards south, and had moved 0. 83kin towards east; （2） CBERS -2 CCD band - 5 had moved 0. 74km towards south, and had moved 0. 11 km towards east; （3） spatial displacement of CBERS -CCD data band -5 must be solved properly when it is used in every project.
