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