Defining an Exact Geographic Location

An exact location specifies precise coordinates on Earth. Common systems:

• Geographic (lat/long): Degrees, minutes, seconds (e.g., 40°42'56"N, 74°00'26"W).
• UTM: 60 zones, easting/northing in meters.
• MGRS: Military grid with zone, 100km square, finer digits.
• Geodetic datum: Reference ellipsoid (WGS84, NAD83, ED50).

Always state coordinate system and datum for accuracy.
