Thematic Map: Poverty Rates

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: Small Scale Maps: show a small amount of detail over a large area. e.g. 1: , 1: *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 AreaDetailExample Large Scale Maps (1: or less) SmallA lot (LOTS) (streets, schools, railways, …) Topographic maps, road maps, city bus maps Small Scale Maps (1: or more) LargeA little (SMALL) (borders, lakes, large rivers, …) Globes, world maps, atlases

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” 1 cm = 10 km

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: cm : cm
