Topographic Map


Topographic Maps are used to show three-dimensional surfaces such as earth, by using contour lines to express elevation changes. For example, mountains are picture by imagining a flat horizontal line that has been sliced through the mass. Each quadrangle has a name and is printed on the map to easily located neighboring pieces of land. There is also a scale that shows the grid, interval, and declination on the map.
