In other cases, you may need to make decisions about that coordinate system to use. Although neither shape nor linear scale is truly correct, the distortion of these properties is minimized in the region between the standard parallels. MAP PROJECTION • A map projection is a systematic transformation of the latitudes and longitudes of locations on the surface of a sphere or an ellipsoid into locations on a plane. They both use the same projection but different projection parameters. ... Albers Equal Area.
