give any three marginal information found in topographical maps

1 answer

Topographical maps are detailed representations of terrain that include various features. Here are three types of marginal information typically found on topographical maps:

  1. Scale Information: This includes the map scale, which indicates the ratio of distance on the map to the actual distance on the ground (e.g., 1:50,000). It may also include a graphical scale bar that helps users estimate distances directly on the map.

  2. Legend/Key: The legend explains the symbols and colors used on the map, providing information about various features such as roads, trails, water bodies, elevation contours, vegetation types, and land use.

  3. Grid Reference System: This is often a coordinate system (like latitude and longitude or UTM) that helps users locate specific points on the map. Marginal information may include a grid overlay to assist in navigation and orientation.

These elements enhance the map's usability, allowing for better interpretation and navigation in the real world.
