Equal-Area Projection


A map projection in which areas on a sphere, and the areas of any features contained on it, are mapped to the plane in such a way that two are related by a constant scaling factor. No projection can be both equal-area and conformal, and projections which are neither equal-area nor conformal are sometimes called aphylactic (Snyder 1987, p. 4). Equal-area projections are also called equivalent, homolographic, homalographic, authalic, or equiareal (Lee 1944; Snyder 1987, p. 4).
