The Winkel tripel projection (Winkel III), a modified azimuthal[1] map projection of the world, is one of three projections proposed by German cartographer Oswald Winkel (7 January 1874 – 18 July 1953) in 1921. The projection is the arithmetic mean of the equirectangular projection and the Aitoff projection:[2] The name tripel (German for 'triple') refers to Winkel's goal of minimizing three kinds of distortion: area, direction, and distance.[3]
