What is the primary purpose of using topographic maps?

The primary purpose of using topographic maps is to show elevation and terrain features. These maps provide a detailed representation of the Earth's surface, highlighting variations in terrain such as mountains, valleys, hills, and depressions. The elevation is indicated through contour lines, which connect points of equal elevation; this helps users understand the three-dimensional shape of the landscape in a two-dimensional format.

Topographic maps are particularly useful for outdoor activities such as hiking, camping, and land-use planning, as they allow users to gauge the difficulty of terrain and plan routes accordingly. Additionally, they can reveal natural features such as rivers and lakes, providing essential information for various applications in geography, geology, and environmental studies.
