摘要
通过回顾当今国际上主要的全球空间基准ITRF的实现过程,介绍了CGCS2000坐标系的建立过程.对于实施CGCS2000坐标系后控制点转换,提出采用基于大地微分公式的坐标转换方法;对于图件转换,总结了需要解决的正北方向的确定、图幅网格化、图幅接边等关键问题.
This paper reviews the realization process of the current main International Terrestrial Reference Frames（ITRF） and introduces the establishing procedure of CGCS2000 coordinate system in China.For the control points coordinate transformation after the implementation of China Geodetic Coordinate System 2000（CGCS2000）,the author gave the coordinate transformation methods based on geodetic coordinate differential formula.Following,some issues about the map conversion such as the true north determination,map sheet gridding and the map merging problems was discussed in this paper.
