South Dakota Topographical Map

On a topographical map, sometimes called a topo map, contour lines are often used to join points of equal elevation above sea level and color gradations may depict elevation ranges between the contour lines.  Topographical maps are often used to determine areas and routes where the terrain is fairly level or where steep slopes exist.  This page includes both static and interactive topographical maps of South Dakota.
