A **map projection** is any method of representing the surface of a sphere or other three-dimensional body on a plane. Map projections are necessary for creating maps. All map projections distort the surface in some fashion. Depending on the purpose of the map, some distortions are acceptable and others are not; therefore different map projections exist in order to preserve some properties of the sphere-like body at the expense of other properties. There is no limit to the number of possible map projections.

### Famous quotes containing the words projection and/or map:

“Those who speak of our culture as dead or dying have a quarrel with life, and I think they cannot understand its terms, but must endlessly repeat the *projection* of their own desires.”

—Muriel Rukeyser (1913–1980)

“Unless, governor, teacher inspector, visitor,

This *map* becomes their window and these windows

That open on their lives like crouching tombs

Break, O break open,”

—Stephen Spender (1909–1995)
