Map scale refers to the relationship (or ratio) between distance on a map and the corresponding distance on the ground. For example, on a 0000 scale map, 1cm on the map equals 1km on the ground.

Ratio or ?Representative Fraction? (RF): A scale of ,000 means that every feature on the map is shown at one thousandth of its actual size. Map units per unit or ?Verbal Scale?: A scale of one inch = 100 miles means that every inch on the map corresponds to 100 miles on the earth.

If a map has a larger scale, it means that it has more detail, but it will also have less scope. Alternatively, a smaller-scale map will have less detail, but it will also be more expansive. For example, a ,000,000 map will show you an entire country. Whereas a scale of 0 can represent someone's backyard.

If a map has a larger scale, it means that it has more detail, but it will also have less scope. Alternatively, a smaller-scale map will have less detail, but it will also be more expansive. For example, a ,000,000 map will show you an entire country. Whereas a scale of 0 can represent someone's backyard.

A map scale might be given in a drawing (a graphic scale), but it usually is given as a fraction or a ratio-1/10,000 or ,000. These "representative fraction" scales mean that one unit of measurement on the map 1 inch or 1 centimeter represents 10,000 of the same units on the ground.

Representative Fraction For example, scale that has a RF of 0 means that every one unit on the map equals one hundred of the same units on the ground. In comparable terms a RF scale of ,200 is the same scale as a verbal scale of 1? = 100?.

Using numbers, scale can be shown as a representative fraction, or RF (for example, 1 1000), or as a ratio (for example, 00). If a map has a scale of 00, then one unit of measurement (e.g. 1 centimetre) on the map shows 1000 of the same units (in this case, 1000 centimetres, which is 10 metres) on the ground.
