GPS座標形式 - XML

GPS座標形式は、緯度と経度を用いて地球上の位置を数値的に表現する方法です。主な形式には、十進法(Decimal Degrees)、度分秒(DMS - Degrees Minutes Seconds)、度分(DDM - Degrees Decimal Minutes)の3つがあり、それぞれ用途に応じて使い分けられます。また、UTM(Universal Transverse Mercator)やMGRS(Military Grid Reference System)などの平面座標系も存在します。これらの形式間での正確な変換は、測量、航空、航海、地図アプリケーションなどで重要となります。
