浅谈2000国家大地坐标系统

Study on CGCS2000

2008年7月1日正式启用2000国家大地坐标系(文中简称2000坐标系统),标志着我国已由参心坐标系走入地心坐标时代。2000坐标系是我国大地测量工作者几十年辛勤劳动的成果。文中通过研究相关的文献,对2000坐标系统的相关知识进行了学习总结。在分析国内外地心坐标系建设概况基础上全面研究分析2000坐标系统。

The official opening of CGCS2000 ( the 2000 National China Geodetic Coordinate System) on July 1,2008 marks a new era of geocentric coordinates from reference-ellipsoid-centric coordinate system.CGCS2000 is a great achievement of decades of hard work by geodetic surveyors.Based on the relative study the author summarizes the information about CGCS2000.Furthermore,the paper makes a comprehensive analysis of it on the basis of the overview of geocentric coordinate system both at home and abroad.
