Grid references
A grid of squares helps the map-reader to locate a place. The vertical lines are called eastings. They are numbered - the numbers increase to the east. The horizontal lines are called northings as the numbers increase in an northerly direction.
Things to remember:
- When you give a grid reference, always give the easting first: "Along the corridor and up the stairs".
Four-figure grid references can be used to pinpoint a location to within a square. To find the number of the square:
- Start at the left-hand side of the map and go east until you get to the bottom-left-hand corner of the square you want. Write this number down.
- Move north until you get to the bottom-left corner of the square you want. Look at the number of this grid line and add it to the two-digit number you already have. This is your four-figure grid reference.
In this case, the tourist information office is in grid square 4733.
