Topography.

http://en.wikipedia.org/wiki/Topography

Topography is a field of planetary science comprising the study of surface shape and features of the Earth and other observable astronomical objects including planets, moons, and asteroids. It is also the description of such surface shapes and features (especially their depiction in maps). The topography of an area could also mean the surface shape and features themselves.

Topography specifically involves the recording of relief or terrain, the three-dimensional quality of the Surface.
