Topography combines top- with graph-, a root meaning "write" or "describe". The topography of the Sahara Desert features shifting sand dunes and dry, rocky mountains. A topographic (or topo) map not only shows the surface features of a region but also indicates the contours and approximate altitude of every location, by means of numerous curving lines, each indicating a single elevation. In other words, it shows a "three-dimensional" picture on a two-dimensional surface. Topo maps are commonly used by hikers, surveyors, government workers, and engineers, among other people.
