Non-perspective Projections Azimuthal Equidistant Equidistant. The distance between any two points on a straight line passing through the center of the projection is shown at true scale. Can view the entire Earth. Used in the polar aspect for maps of polar regions, and the Northern and Southern Hemispheres. Lambert Azimuthal Equal-Area Equal Area Can view the entire Earth.
Scale is true only at the center but in all directions.
Frequently used in the polar aspect in atlases for maps of polar regions and of the Northern and Southern Hemispheres. The equatorial aspect is used for atlas maps of the Eastern and Western Hemispheres. The oblique aspect is used for atlas maps of continents and oceans. Recommended for equal-area maps of regions that are nearly circular. Airy Neither conformal nor equal area.
