Map Scale

Is this to scale?

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.

Scale Area Large Scale Small Maps (1: 50 000 or less) Large Small Scale Maps (1: 250 000 or more) Detail Example A lot (LOTS) (streets, schools, railways, …) Topographic maps, road maps, city bus maps A little (SMALL) (borders, lakes, large rivers, …) Globes, world maps, atlases

Map Scale Direct Statement (DS): a sentence about a distance on a map compared to the actual distance in real life. e. g. “one centimetre represents four kilometres” “three centimetres represents eight kilometres”

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

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”
