The concept of scale the scale of a map is the ratio between distances on the map and corresponding distances in the real world o if a map has a scale of 1:50,000, then 1 cm on the map equals 50,000 cm or 0.5 km on the Earth's surface the use of the terms "small scale" and "large scale" is often confused, so it is important to be consistent o a large scale map shows great detail, small features representative fraction is large, e.g. 1/10,000 o a small scale map shows only large features representative fraction is small, e.g. 1/250,000 the scale controls not only how features are shown, but what features are shown o a 1:2,500 map will show individual houses and lamp posts while a 1:100,000 will not different scales are used in different countries o in the US, 1:100,000 is the largest scale at which complete coverage of the continental states exists, but there is limited coverage at 1:62,500 and 1:24,000 o in the UK, there is complete coverage at much larger scales (1:1,250 to 1:10,000)
