A family of map projections that includes as special cases Mollweide projection, Collignon projection, and the various cylindrical equal-area projections. 1932 Wagner VI: Pseudocylindrical Compromise K. H. Wagner: Equivalent to Kavrayskiy VII vertically compressed by a factor of /. c. 1865: Collignon
A medieval depiction of the Ecumene (1482, Johannes Schnitzer, engraver), constructed after the coordinates in Ptolemy's Geography and using his second map projection. In cartography, a map projection is any of a broad set of transformations employed to represent the curved two-dimensional surface of a globe on a plane.
The Dymaxion map projection, also called the Fuller projection, is a kind of polyhedral map projection of the Earth's surface onto the unfolded net of an icosahedron. The resulting map is heavily interrupted in order to reduce shape and size distortion compared to other world maps , but the interruptions are chosen to lie in the ocean.

All projections distort geographic features, distances, and directions in some way. The various map projections that have been developed provide different ways of balancing accuracy and the unavoidable distortion inherent in making world maps. Perhaps the best-known projection is the Mercator Projection, originally designed as a nautical chart.
The Tobler hyperelliptical projection is a family of equal-area pseudocylindrical map projections first described by Waldo R. Tobler in 1973. The imagery used for the map is derived from NASA's Blue Marble summer months composite, with oceans lightened to enhance legibility and contrast.
One of Tobler's largest interests, especially early in his career, was map projections, with much of his dissertation focusing on them. [3] He is the inventor of novel and unusual map projections, including the family of Tobler hyperelliptical projections and the first derivation of the partial differential equations for area cartograms.
The Gall–Peters projection of the world map. The Gall–Peters projection is a rectangular, equal-area map projection. Like all equal-area projections, it distorts most shapes. It is a cylindrical equal-area projection with latitudes 45° north and south as the regions on the map that have no distortion. The projection is named after James ...
