Also called Orthophanic, Robinson is a compromise projection used for world maps.
Pseudo cylindrical. Meridians are equally spaced and resemble elliptical arcs, concave toward the central meridian. The central meridian is a straight line 0.51 times the length of the equator. Parallels are equally spaced straight lines between 38° N and S; spacing decreases beyond these limits. The poles are 0.53 times the length of the equator. The projection is based on tabular coordinates instead of mathematical formulas.
All parallels and the central meridian.
Neither conformal nor equal area. Useful only for world maps.
Developed for use in general and thematic world maps.
Used by Rand McNally since the 1960s and by the National Geographic Society since 1988 for general and thematic world maps.
