Topographic Map

A topographic map is used to show the elevation of an area. The most common topographic maps that are used today are from the U.S.G.S which has documented the contiguous 48 states with 7.5 minute 1:24,000 scale topographic maps. These maps depict areas of elevation through contour lines such as the one seen of Crater Lake in Oregon above. The map shows the elevation of both the elevated crater walls and also the sunken down lake.
