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 ...
Gott, Goldberg and Vanderbei’s double-sided disk map was designed to minimize all six types of map distortions. Not properly "a" map projection because it is on two surfaces instead of one, it consists of two hemispheric equidistant azimuthal projections back-to-back.

Therefore, more generally, a map projection is any method of flattening a continuous curved surface onto a plane. [citation needed] The most well-known map projection is the Mercator projection. [7]: 45 This map projection has the property of being conformal. However, it has been criticized throughout the 20th century for enlarging regions ...
The map engendered controversy. The map projection Peters claimed to have developed had been presented more than a century earlier by the Reverend James Gall, and, despite Peters's claims, the projection was not the first or only equal-area projection. Many other of his claims were disputed or debunked.

Yet his projection remains the authority all the same. Today, when children learn geography in school, they might not see Mercator’s poorly proportioned countries and continents on a wall-mounted map. But they will likely see it through the glare of a screen: even Google Maps uses the Mercator projection.
Map projection has been used to create cartographic propaganda by making small areas bigger and large areas bigger still. [18] Arno Peters' attack on the Mercator Projection in 1972 is an example of the subjectivity of map projection; Peters argued that it is an ethnocentric projection. [19]
