如何計(jì)算1緯度和1經(jīng)度間的距離由于地球是一個類圓的球體，不同地域1緯度的縱向間距離是一樣的，但經(jīng)度間的橫向距離是和所處的緯度相關(guān)。在北極或南極點(diǎn)上，所有的經(jīng)線都匯聚于一點(diǎn)，因此所有經(jīng)度間的距離都為0，在赤道上，所有的經(jīng)線都分散得最開，每條經(jīng)線間的距離也最大。明白了以上的原理，就容易明白得如何計(jì)算了。假設(shè)地球在A緯度的周長為L,那么A緯度間的距離為L/360，而在緯度為A的地域，其平行于赤道的圓周長為L*cosA（那個畫張圖，依照半徑的比就明白了），相應(yīng)的1經(jīng)度間的橫向距離為L*cosA/360。赤道的實(shí)際周約長為40000km，代入上面的公式就能夠夠大致估算出1緯度間的縱向距離為111km，緯度為A的地域的1經(jīng)度間的橫向距離為cosA*111km。北半球緯度、經(jīng)度的1度1分1秒對應(yīng)的方向、距離各是多少？一、不同緯度的間距差是相同的，緯度（赤道）一度合110.94千米，一分合1.849千米，一秒合30.8米。緯度數(shù)值加大時，位置北移，減小時那么位置南移。二、經(jīng)度差對應(yīng)的東西方向距離因其所處的緯度不同而不同，在北半球的東經(jīng)差數(shù)見下表：緯度東半球經(jīng)度差對應(yīng)的東西方向距離1°1’1〃北緯51°70公里1.17公里19.50米北緯44°80公里1.33公里22.21米
