Map scale shows the relationship between distance on a map and the actual distance on the ground. It is usually represented as a ratio, a statement, or a linear scale. Large scale maps cover small areas with more detail, such as city maps. Small scale maps cover large areas with less detail, like world maps. Understanding map scale is essential for accurate measurement and interpretation. It helps readers estimate distances, compare sizes of places, and understand how much detail a map can realistically show within its given space.
