The Gall–Peters projection, named after James Gall and Arno Peters, is one specialization of a configurable equal-area map projection known as the equal-area cylindric or cylindrical equal-area projection. It achieved considerable notoriety in the late 20th century as the centerpiece of a controversy about the political implications of map design.
Maps based on the projection are promoted by UNESCO, and they are also widely used by British schools.[1]
