To determine distances on a topographic map, you would use which feature located at the bottom of the map?

The bar scale, located at the bottom of a topographic map, is a crucial feature for determining distances. It is a graphical representation that shows the relationship between the distance on the map and the actual distance on the ground. Users can measure the distance on the map with a ruler or their fingers and then translate that measurement into real-world distance using the bar scale, which typically displays various increments such as miles or kilometers.

Utilizing the bar scale effectively allows people to accurately gauge distances, which is essential for navigation, planning routes, and conducting search and rescue operations in the field where precise locations are critical. Each section of the scale correlates with a specific real-world distance, making it a reliable tool for anyone using topographic maps.
