Topographic maps use contour lines to show elevation.
Topographic maps, often called "topo maps," feature contour lines to portray the shape and elevation of the land.
Contour lines (lines of equal elevation) that are close together indicate steep terrain, while lines that are far apart indicate flat terrain.
Such maps also usually portray both natural and artificial features. They show and name natural land formations such as mountains, valleys, plains, lakes, rivers and vegetation. They also identify particular man made features such as roads, boundaries, transmission lines and major buildings.
