Coordinates or Grid References?

Some may prefer the more precise definition that coordinates are where the main vertical and horizontal lines on a map intersect (therefore an exact location) and grid references are in between these lines (and therefore not as an exact location).

This logic is that a ‘grid reference’ is only a ‘coordinate’ where the main lines meet. This ‘logic’ falls apart when one considers that the coordinates referenced may be part of a larger graticule and therefore they may be inside other coordinate lines.

How to describe a Coordinate/Grid Reference

There are numerous coordinate systems:

Degrees Minutes Seconds (DMS)
Universal Transverse Mercator (UTM)
Military Grid Reference System (MGRS)
