GRID REFERENCES MADE EASY
A GRID REFERENCE is a number which gives a location on a map
They are very useful when we’re out hiking
We can use them to find out where we’re supposed to be…
...or if we get lost we can tell someone where we are!
S
GRID REFERENCES MADE EASY
The grid references we usually use are SIX FIGURE references
They will look something like this:
216409A bit like a phone number!
S
GRID REFERENCES MADE EASY
These numbers refer to the GRID which covers all maps
Here they’re marked in PINK so you can see them, but they’re usually BLUE
S
GRID REFERENCES MADE EASY
The grid is labelled with GRID NUMBERS at the bottom and left sides of the map
20 21 22 2340

GRID REFERENCES MADE EASY
20 21 22 23
The numbers at the bottom are called EASTINGS because they label grid lines which go EAST
S
GRID REFERENCES MADE EASY
The numbers at the Left are called NORTHINGS because they label grid lines which go NORTH

Each Easting refers to the column to the right of it’s grid line

Each Northing refers to the row above it’s grid line

Where are these EASTINGS and NORTHINGS in the Grid Reference?
21640921 40EASTING NORTHING
S
GRID REFERENCES MADE EASY
Both numbers combined give a square on the map...
4021
The grid reference of this square is 21 40
S

How do you remember WHICH COMES FIRST though?
Well, just remember
EASTINGS FIRSTEASTINGS FIRST…and that EASTINGS are the numbers along the bottom, labelling the lines that go EAST!

EXERCISE ONEFIND THE SQUARE
You’ll have a map between two, and a list of 6 figure grid references - just find the big square for each one

OK so we now know how to find the square from these numbers:
21640921 40But what about these ones?
6 9
What are they for?
S
GRID REFERENCES MADE EASY
Well the 21 and 40 only give you a big square one kilometre wide!
4021
Not much use if you need to know where to go exactly!
1km
S
GRID REFERENCES MADE EASY
So we split each square into 100 smaller squares...
S
GRID REFERENCES MADE EASY
Each square is labelled like the grid before, but with just one number from 0 to 9
0 1 2 3 4 5 6 7 8 9
9876543210
S
GRID REFERENCES MADE EASY
So, same as before, a square is identified by an EASTING and a NORTHING
Remember, EASTING first
0 1 2 3 4 5 6 7 8 9
9876543210
So what’s the two numbers which identify this square?
S
GRID REFERENCES MADE EASY
That’s right: 4 and then 7
4 first as it’s the EASTING
0 1 2 3 4 5 6 7 8 9
9876543210
S
GRID REFERENCES MADE EASY
Then 7 as it’s the NORTHING
0 1 2 3 4 5 6 7 8 9
9876543210

OK, let’s put it all together…
See the spot height marked 375 in the square below?

But where does this fit into the 6 figure reference?
