摘要
介绍"新昆明坐标系"的椭球定位及参数,分析与国家大地基准的关系,对坐标方位角进行研究。选取"新昆明坐标系"具有代表性的3个高程归算面,计算方位角与80西安坐标系的变化量。通过研究表明,"昆明坐标系"在一定的范围内,其方位角与国家坐标系的方位角基本保持一致,完全能满足各类工程建设控制测量的要求。
The ellipsoid positioning in the new Kunming coordinate system is introduced in this paper, and its relationship with the national geodetic datum is analyzed. The coordinate azimuth in the system is studied. Three representative elevations of coordinate system is used to calculate the variation of azimuth with 80 Xi＇an coordinate system. Through research shows that the in a certain area the azimuth is equivalent with the national coordinate system, and can meet all kinds of construction control measurement requirements.
