- Aitoff_projection abstract "The Aitoff projection is a modified azimuthal map projection. Proposed by David A. Aitoff in 1889, it is the equatorial form of the azimuthal equidistant projection, but stretched into a 2:1 ellipse while halving the longitude from the central meridian:where and are the x and y components of the equatorial azimuthal equidistant projection. Written out explicitly, the projection is:whereand is the unnormalized sinc function with the discontinuity removed. In all of these formulas, is the longitude from the central meridian and is the latitude.Three years later, Ernst Hermann Heinrich Hammer suggested the use of the Lambert azimuthal equal-area projection in the same manner as Aitoff, producing the Hammer projection. While Hammer was careful to cite Aitoff, some authors have mistakenly referred to the Hammer projection as the Aitoff projection.".
