Ratio scale (cartography)
The ratio scale, also known as the representative fraction, is a way to express the relationship between the size of an object on a Map and its size in reality, commonly used in Cartography. It is a fundamental concept in understanding how Maps represent the world, allowing users to measure distances and calculate sizes of features. The ratio scale is often expressed as a fraction, such as 1:10,000, indicating that one unit on the map represents 10,000 units in reality. This concept is closely related to Scale (cartography), which is essential for Navigation, Surveying, and Geographic information system applications. Understanding ratio scales is crucial for accurately interpreting Maps and making informed decisions in various fields, including Urban planning, Environmental health, and Conservation biology.
