DMS is traditional in navigation, surveying, and aviation. It provides intuitive subdivisions and is easier to read on maps.

GPS uses latitude (N/S from equator, 0° to 90°) and longitude (E/W from Prime Meridian, 0° to 180°) in either DMS or decimal format.

For GPS: 6 decimal places ≈ 0.1m accuracy. Seconds to 2 decimal places is comparable precision.
