1. 4 Figure Grid References

2. Ordnance Survey Maps The horizontal lines that run across a map are called northings - they increase in value as they go up the map from the bottom. The vertical lines that run across a map are called eastings - they increase in value as they go across the map from left to right.

3. 4 figure grid reference It is straightforward to find a specific place using a grid reference. Grid references are easy if you can remember that you always have to go along the corridor before you go up the stairs. - To find the number of a square first use the eastings to go along the corridor until you come to the bottom left-hand corner of the square you want. Write this two-figure number down. - Then use the northing to go up the stairs until you find the same corner. Put this two-figure number after your first one and you now have the four-figure grid reference.
