What is the purpose of the marginal information on a map?

The purpose of marginal information on a map is to detail specific features and legends, which includes essential contextual information that aids in the proper interpretation and use of the map. This information often encompasses symbols, colors, and lines used to represent various geographical elements, making it crucial for understanding what the map indicates about terrain, political boundaries, roads, and other significant features.

When users consult a map, the marginal information clarifies how to read and make sense of various symbols, ensuring that the users can navigate effectively and understand the geographical context. This aspect is particularly important in military operations where precise navigation and situational awareness are critical. Therefore, the inclusion of this detailed information allows users to accurately assess their environment and make informed decisions based on the map.
