Wagner VI projection of the world.

Wagner VI is a pseudocylindrical whole Earth map projection. Like the Robinson projection, it is a compromise projection, not having any special attributes other than a pleasing, low distortion appearance. Wagner VI is equivalent to the Kavrayskiy VII horizontally elongated by a factor of {2}/\sqrt{3}. This elongation results in proper preservation of shapes near the equator but slightly more distortion overall. The aspect ratio of this projection is 2:1, which is equal to that of the Equirectangular projection.

The Wagner VI is defined by:[1]

x = \lambda \sqrt{1 - 3\left(\frac{\phi}{\pi}\right)^2}
y = \phi\,.
