2. Large Scale and Small Scale Maps
Scale determines the amount of detail a map will show.
Large Scale Maps: show a large amount of detail and a small area.
e.g. 1:50 000, 1:25 000
Small Scale Maps: show a small amount of detail over a large area.
e.g. 1: , 1:

5. Map Scale
Direct Statement (DS): a statement about a distance on the map in comparison to the represented distance in the real world.
e.g. “one centimetre represents four kilometres”
“three centimetres represents eight kilometres”

6. Map Scale
Linear Scale (LS): a straight line divided into units which can be used for measuring distance on a map.

7. Map Scale
Representative Fraction (RF): a fraction that involves no mention of units. Because units are ignored, whatever you assign to one side must be assigned to the other.
e.g. 1: could become,
1 cm : cm or,
1 m : m or,
1 “size 11 boot” : “size eleven boots”
