Map Skills

Q1 in Paper 2 is always map skills.  As long as you remember the basic techniques of map-work you should have no problem with this section.

 

Grid References

Remember: go across first, then go up the side.

4fig4 Figure Grid References

4 figure grid references locate the square that a feature is in.

Orange circle =  01 10

Blue square = 02 11

Green Triangle =03 10

 

6 Figure Grid References

These locate the exact position on a map.

6-figEach grid square is broken into 100 smaller squares.

Find the grid line going across and the divide the square into tenths (like a decimal).

Do the same on the vertical axis.

Think of the extra digits as decimals but without the dot.

Blue square = 023 111

Orange Square = 014 105

Green triangle = 028 101

 

Measuring Height

The main way that height is shown on OS maps (used in the exam) is contour lines.contours

These are brown lines that run along places that are the same height.

The closer together they are the steeper the slope.

Contour lines can vary in the height increase that they show (usually 10m or 20m) so check the map key.

Spot heights are used to show the top of a hill/mountain and they give the exact height in meters.

 

Measuring Distance

Straight line distance: measure the direct distance between the two stated points.  Use the scale underneath the map extract to work out the distance in km or miles.

Curved line distance: if asked to measure the distance along a road you need to use a piece of paper to measure the distance.  Mark the end of each straight section and the turn the paper following the curve to measure the next straight section.  Use the scale to give the correct distance.
