Which coordinate system are these coordinates pertaining to? 16R 315000e 3365000n

• A. MGRS
• B. Lat/Long
• C. NAD27
• D. UTM

Answer: (D)

These coordinates are in a zone-based projected system that uses meters for the x and y values. The key clue is the zone designation paired with easting and northing figures: a zone and latitude band (16R) followed by an easting of 315000 meters and a northing of 3365000 meters. That format is characteristic of UTM coordinates, where the world is divided into 60 longitudinal zones and each zone has a latitude band letter. The easting value indicates how far east you are from the zone’s central meridian, and the northing value shows how far north you are from the equator, both in meters. The numbers look like typical UTM measurements in the northern hemisphere, rather than decimal degrees (Lat/Long) or a MGRS string that would include an additional 100 km square designator. NAD27 refers to a datum, not the coordinate format itself. So these coordinates pertain to the UTM system.
