| Abstract: | 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. |
