First look for the map s scale which will let you know how much detail the map contains. Locate a tall peak or hill in your area and refer to the map. As mentioned before topographic maps use a system of lines to indicate elevation.

Topographic maps go further giving you the power to visualize three dimensional terrain from a flat piece of paper.

A contour linerepresents a constant elevation as it follows the shape of the terrain.
This interval should be clearly stated on the bottom of the map.
