Hammer-Aitoff Projection Map Projection
sometimes named Hammer- projection
"A common modification was devised [from Lambert azimuthal equal area] by ernst Hammer in 1892 and is called the Hammer or Hammer- Aitoff projection.It consists of halving the vertical coordinates of the equatorial aspect of one hemisphere and doubling the values of the meridians from center. It retains equality of area, but it is no longer azimuthal" [Snyder 1987, p. 182]
