GPS座標形式 - TOML
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。
