Goode's 80th!

Abstract

In 1925, Professor J. P. Goode of the University of Chicago Geography Department superimposed a sinusoidal and a Mollweide (homolographic) projection and noted similarities in the maps on either side of the equator [3]. Eureka! The "homolographic" projection was born (Figure 1). Anderson and Tobler note that the "kinks" in the edge of the Goode homolosine, at about 40 degrees north and south latitude, show where the Mollweide is joined to the sinusoidal: sinusoidal is central and Mollweide is polar [1]. This familiar equal area interrupted projection is often used to display global distributions of terrestrial phenomena.
