2. Grids and grid coordinates
The geographic grid system
was created to locate all
places on Earth.
It uses latitude and
longitude to describe
the location of any
place on Earth.
3. Grids and grid coordinates
One way of mapping
the world is on a globe,
because Earth is a sphere,
which is a 3D shape.
A map is usually a
2D drawing, and
shows an accurate
image of a place.
Most people find 2D maps
easier to use than globes.

18. Eastings, northings and area references
This diagram uses a different type of grid system.
It is made up of numerals located on grid lines.
19. Eastings, northings and area references
The numbers that refer to the vertical grid lines
are called eastings.
20. Eastings, northings and area references
They increase in value as you move across
in an easterly direction.
21. Eastings, northings and area references
The numbers that refer to the horizontal grid lines
are called northings.
They increase in value as you move up in a
northerly direction.
22. Eastings, northings and area references
The two eastings numbers are joined with
the two northings numbers to make a
four-figure area reference.
23. Eastings, northings and area references
For example, a % symbol is located at eastings 46
and northings 22, so its area reference is 4622.
24. Eastings, northings and area references
Which symbol appears at these area references?
4124
Answer –
4425
Answer –
4323
Answer –
4120
Answer –
25. Grid references
Grid references locate places on a map more
accurately than area references.
A grid reference is a six figure number, made up
of a three-figure eastings reading and a three-figure
northings reading.
A grid reference is found by mentally subdividing
each grid square into tenths.
The third figure in each eastings and northings
reading is found by estimating how many tenths
across or up the exact location is.
26. Grid references
What is the grid reference for the Post Office?
Answer – 283579
27. Grid references
Name the feature at 280570.
Answer – An island
28. Grid references
Name the feature at 258576.
Answer – The river mouth
29. Grid coordinates – latitude and longitude
To locate different places
around Earth, we use
geographic coordinates –
measurements of
latitude and longitude.
Lines of latitude are
imaginary parallel lines
that circle the globe in an
east–west direction.
30. Grid coordinates – latitude and longitude
The Equator divides Earth into
northern and southern hemispheres.
Latitude measures how many degrees north
or south a point on Earth lies from the Equator.
31. Grid coordinates – latitude and longitude
What is the name given to the imaginary line of
latitude at:
23.5O south of the Equator?
Tropic of Capricorn
32. Grid coordinates – latitude and longitude
What is the name given to the imaginary line of
latitude at:
23.5O north of the Equator?
Tropic of Cancer
33. Grid coordinates – latitude and longitude
What is the name given to the imaginary line of
latitude at:
66.5O south of the Equator?
Antarctic Circle
34. Grid coordinates – latitude and longitude
What is the name given to the imaginary line of
latitude at:
66.5O north of the Equator?
Arctic Circle
35. Grid coordinates – latitude and longitude
Lines or meridians of longitude are imaginary lines
between the North and South Poles.
36. Grid coordinates – latitude and longitude
Longitude measures how many degrees east or west
a point on Earth is from the Prime Meridian.

Find out why it is given this name.
Suggest why it is this shape.
International Date Line
40. Grid coordinates – latitude and longitude
The exact location of any
place on Earth is given by
its geographic coordinates.
You can find examples in
the index of your atlas.
Measurements for latitude
and longitude are given in
degrees (and minutes).
Latitude is stated first,
then longitude.
