2000国家大地坐标系下点位坐标转换方法浅析

A Discussion on Methods for Transforming Point Position Coordinate from Previous Geodetic Coordinate System to next Generation CGCS 2000

简单回顾了我国现行大地坐标系的定义及其不足之处,介绍了2000国家大地坐标系(CGCS 2000)的定义、实现及其特点,从理论上详细介绍了点位坐标由我国现行大地坐标系向2000国家大地坐标系(CGCS 2000)转换的几种方法,并对这些转换方法进行了对比分析。

This paper briefly introduces the previous geodetic coordinate system in China,inlcuding its definition and deficiency. Then presents CGCS 2000,introduces its definition,realization and advantages subsequently. This paper introduces several methods for transformng Point Position Coordinate from previous Geodetic Coordinate System to next generation CGCS 2000 theoretically, and gives an analysis and comparison of these methods.
