What is the purpose of the legend on a map?

The purpose of the legend on a map is to identify the symbols used on the map. The legend, often found in a corner of the map, serves as a key that explains what various symbols, colors, and markings represent, making it easier for users to interpret the information accurately. For example, it might indicate what different colors signify, such as water bodies, forests, or urban areas, and provide clarity on symbols that represent roads, trails, or landmarks. Understanding the legend is essential for effective navigation and comprehension of the map's details, enabling users to gather relevant geographical information quickly and accurately.
