Littrow projection
Encyclopedia
The Littrow projection is the only conformal retroazimuthal map projection
. A retroazimuthal projection is one in which the direction to a fixed location B (the bearing at the starting location A of the shortest route) corresponds to the direction on the map from A to B.
The Littrow projection allows direct measurement of the azimuth from any point on the map.
The Littrow projection was created in 1833 by Joseph Johann Littrow
(1781 – 1840). It is sometimes referred to as a Weir Azimuth diagram.
Map projection
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...
