map in your textbook on page 140-141 to find the answers.

ALL 8 POINTS OF
THE COMPASS ROSE
SO YOU CAN QUOTE
DIRECTIONS WHEN
YOU USE A MAP
Use these examples to help you:
Bamford is NORTH-EAST Thornhill
Shatton is SOUTH of Thornhill
Offerton Moor is SOUTH-EAST of
Westfield
Brough is NORTH of Elmore Hill Farm
Aston is WEST of Bamford
Bamford is EAST of Aston
Thornhill is SOUTH-WEST of Bamford

Scale
The scale of a map allows a reader to calculate the size, height and dimensions of the features
shown on the map, as well as distances between different points. The scale on a map is the
ratio between real life sizes and how many times it has been shrunk to fit it on the map.
The scale below is for a 1:50,000 scale map. At this scale, 1 cm on the map represents 50,000
cm on the ground (= 500 metres or 0.5 kilometres).

Symbols and Map Keys
Symbols are used on a map
instead of drawing the
exact thing to save space –
imagine trying to draw all
the houses and trees on!

textbook on page 3 #1, 2.
Don’t worry you do not
need to learn them all!
You will always be given
a key to use in an exam!
Latitude and Longitude
Latitude
Measured in degrees NORTH and SOUTH of the Equator.
Lines are parallel to each other running from WEST to EAST.
Longitude
Measured in degrees EAST or WEST of the Prime Meridian.
Lines drawn running NORTH and SOUTH.
4 Figure Grid References
Most maps are divided into small squares by grid lines that run horizontally
(eastings lines) and vertically (northings lines) across the map. Each line has a
number (or sometimes a letter) so we can give a reference for each square to
help us locate where somehting is on a map.
To give a grid reference for a whole grid square we use 4 figure grid references
to locate it on the map. This is how you give a 4 figure grid reference of a square
on a map:
1. First you locate the bottom left hand corner of
the square you want as it is from here that you
take your reading.
2. Then you go along the corridor until you get to
the correct eastings line (those which run side
to side) for your square (31)
3. Then you up the stairs until you find the
correct northings line (which run top to bottom)
for your square (25)
4. So the 4 figure grid reference for the green
square is 3125
SOME EXAMPLES OF 4 FIGURE
GRID REFERENCES TO HELP YOU:
BAMFORD is in grid square 2183
THORNHILL is in grid square 1983
BROUGH is in grid square 1882
ASTON is in grid square 1883
BAMFORD STATION is in grid square
2082
