Topographic Map
Topographic maps represent three dimensional terrain features in a two dimensional format. Contour lines are used to represent the elevation and shape of the land. This example of a topographic map is used to show how firefighters use maps to plan how to fight wild fires. The contour lines are imaginary lines that provide firefighters with valuable information about the terrain.
