1. Map Scale

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. 1:250 000, 1:500 000 *a map of the world that fits on an 8.5 x 11 inch piece of paper has a scale of 1: 100 million.

3. Scale AreaDetailExample Large Scale Maps (1:50 000 or less) SmallA lot (LOTS) (streets, schools, railways, …) Topographic maps, road maps, city bus maps Small Scale Maps (1:250 000 or more) LargeA little (SMALL) (borders, lakes, large rivers, …) Globes, world maps, atlases

14. 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”

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

16. 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: 50 000 could become, 1 cm : 50 000 cm or, 1 m : 50 000 m or, 1 “size 11 boot” : 50 000 “size eleven boots”
