Grid References for Map Navigation

 
4 Figure Grid References
 
 
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.
 
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.
