Answer 2

Answer:

A grid reference is a map reference indicating a location in terms of a series of vertical and horizontal grid lines identified by numbers or letters.

Grid references define locations in maps using Cartesian coordinates. Grid lines on maps define the coordinate system, and are numbered to provide a unique reference to each location on the map. This reference is normally based on projected eastings and northings.
