grid reference
Location on map
A grid reference is a set of coordinates identifying a specific location on a map, typically using letters and numbers that correspond to a grid overlay: The grid reference for the summit is SK 287 875.
Common in British Ordnance Survey maps and military navigation, grid references allow precise communication of positions without ambiguity.
