1樓：
我不太清楚樓主問的什麼，longitude/latitude就是經緯度，而北京五四不是座標，是座標系，ica-75橢球、長軸105m。
mapinfo裡的longitude/latitude中的category members裡有許多座標系可以選擇，不過我印象中沒有北京54。可以在投影中選擇pulkovo座標系----1942基準面(mapinfo中代號為1001)代替北京54座標系
也可以自己寫個prj

不知道你提問的經緯度相反座標是什麼意思，你說的座標也沒有標註是東經還是西經 北緯還是南緯之間的相反座標，或是你想把經緯度換算成標準的度分秒。經度相反的座標是兩個經度加起來 180度。如 東經45度，相反的就是西經135度，某個緯度的相反緯度是兩個座標資料相同符號不同，比如北緯n45度的相反座標是南緯...
經緯度的座標表示方法，地理上的經緯度表示什麼？
夢色十年 w代表西經，s代表南緯，n代表北緯，e代表東經。緯線和經線一樣是人類為度量方便而假設出來的輔助線，定義為地球表面某點隨地球自轉所形成的軌跡。任何一根緯線都是圓形而且兩兩平行。緯線的長度是赤道的周長乘以緯線的緯度的餘弦，所以赤道最長，離赤道越遠的緯線，周長越短，到了兩極就縮為0。從赤道向北和...
