a map projection
equal earth projection









































the equal earth map projection is an equal-area pseudocylindrical projection for world maps, invented by bojan šavrič, bernhard jenny, and tom patterson in 2018. it is inspired by the widely used robinson projection, but unlike the robinson projection, retains the relative size of areas. the projection equations are simple to implement and fast to evaluate.

bullet::::- the curved sides of the projection suggest the spherical form of earth.
equal earth projection
the robinson projection was devised by arthur h. robinson in 1963 in response to an appeal from the rand mcnally company, which has used the projection in general-purpose world maps since that time. robinson published details of the projection's construction in 1974. the national geographic society (ngs) began using the robinson projection for general-purpose world maps in 1988, replacing the van der grinten projection. in 1998 ngs abandoned the robinson projection for that use in favor of the winkel tripel projection, as the latter "reduces the distortion of land masses as they near the poles".
