摘要
在大地测量计算中 ,弦线法可以解决若干大地测量问题。文中介绍了大地线可以表示成椭球上的弦线或曲面线 ,且对任一距离能得到精确的结果。为了使结果达到亚毫米的精度 ,大地线的长度限制在 1 0
Chord-line method can solve many geodetic problems in geodetic calculation.The paper gives some discussions about that geodetic line can be showed as chord-line or irregulare avea-line of elliptic sphere and any distance can be given exact result.For the purpose of reaching the millmicron,the length of geodetic line must be limited within 100 kilometres.
