- 3 things to know
- All three papers
Overview
What the 1:50 000 and 1:25 000 scales mean, grid squares, four-figure and six-figure grid references, measuring straight and winding distances, and the eight compass points.
What you need to know
Answer each one before you reveal it.
On a 1:25 000 map, what distance on the ground do 4 cm represent?
Which shows more detail, a 1:25 000 map or a 1:50 000 map, and why?
Questions from this subtopic
Each one with the model answer underneath.
- 1
On a 1:50 000 map, what distance on the ground does 1 cm represent?
Model answer
500 m, because 50 000 cm is half a kilometre.
- 2
On a 1:25 000 map, what distance on the ground do 4 cm represent?
Model answer
1 km, because each centimetre stands for 250 m.
- 3
Which shows more detail, a 1:25 000 map or a 1:50 000 map, and why?
Model answer
The 1:25 000 map, because everything is drawn twice as large, so small features such as field boundaries can be included.
- 4
How big is one grid square on the ground, and how wide is it drawn at each of the two common scales?
Model answer
One kilometre square on the ground either way, drawn 2 cm across at 1:50 000 and 4 cm across at 1:25 000.
- 5
What does a four-figure grid reference identify?
Model answer
One whole grid square, a square kilometre of ground.
- 6
Which half of a grid reference is read first?
Model answer
The eastings, read along the bottom of the map, before the northings read up the side.
