Topographic Map

This topographic map shows a small area of Salt Lake City and the nearby mountains. Topographic maps use contour lines to show elevation (height above sea level). Contour lines join points of equal elevation above a specified reference, such as sea level. Think of a contour line as an imaginary line on the ground that takes any path necessary to maintain constant elevation. Using the legend for this map, you can locate school, churches, and railroads. People frequently use topographic maps when hiking. Builders use topographic maps to figure out where to put buildings and roads. There's a topographic map like this for every part of the United States, including one for where you live.
