Sometimes people need to find a general area, rather than a specific point on a map. An area reference will allow you find a general location in a grid square. Area references comprise four-figure numbers.
Topographic maps have a grid of lines drawn on them. You can see the lines, some horizontal, some vertical, and each line has a number corresponding to it.
Now coming to a more simple map you can see that the vertical lines are called eastings – and that is because they travel from west to east.
The horizontal lines on the other hand are called northings – and we call them northings because they travel from south to north.
When reading an Area reference you always read the easting first and the northing second.
