Goode homolosine projection
Encyclopedia : G : GO : GOO : Goode homolosine projection
The Goode homolosine projection is an interrupted, pseudocylindrical, equal-area, composite map projection. It is used for world maps. It is useful for raster data representation due to its equal-area property. It is also referred to as Interrupted Goode homolosine projection.
It was developed in 1923 by John Paul Goode to provide an effective alternative to portraying global areal relationships on the Mercator map.
The projection is composed from twelve regions to form six interrupted lobes. The six lobes are the top sections of a Mollweide projection that are carefully grafted on to six interior regions along the equator that are subject to a sinusoidal projection. If one looks carefully along the edges of the lobes, one can see a subtle discontinuity at approximately the 45th parallels. The equal-area nature of the Goode projection follows from the fact that its source projections are themselves both equal-area.
