It shows graphically the relationship between map distance and ground distance. Representative Fraction The scale of a map, expressed as a numerical ratio of map distance to ground distance, is called a Representative Fraction (or RF). It is usually written as 1/50,000 or 1:50,000, meaning that one unit of measurement on the map represents 50,000 of the same units on the ground. Changing Scales The maps show the effects of scale changes moving &quot;closer to&quot; or &quot;farther from&quot; the earth. A large scale map shows a small area with a large amount of detail.
