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.

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 ...

In 1974 he announced the Peters world map, claiming it was the most accurate representation of the world. 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 ...
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]
In recognition of both men the form is now called the Gall-Peters projection. Gall himself was an advocate of accessible mapping for blind people. One format he suggested was to combine Braille printing with twine to indicate lines. An 1851 book included such a map by Gall and his partner Inglis. [10]
In cartography, a conformal map projection is one in which every angle between two curves that cross each other on Earth (a sphere or an ellipsoid) is preserved in the image of the projection; that is, the projection is a conformal map in the mathematical sense. For example, if two roads cross each other at a 39° angle, their images on a map ...
