This projection preserves the area of individual polygons while simultaneously maintaining a true sense of direction from the center. The general pattern of distortion is radial.
It is best suited for individual land masses that are symmetrically proportioned, either round or square. Planar, projected from any point on the globe. This projection can accommodate all aspects: equatorial, polar, and oblique.
Summary and Guide to Projections
A single point, located anywhere, specified by longitude and latitude. Beyond that, angular distortion is more significant; small shapes are compressed radially from the center and elongated perpendicularly.
True at center. Scale decreases with distance from the center along the radii and increases from the center perpendicularly to the radii.
The data must be less than a hemisphere in extent. The Auxiliary Sphere Type parameter accepts 0 use semimajor axis or radius of the geographic coordinate system , 1 use semiminor axis or radius , 2 calculate and use authalic radius , or 3 use authalic radius and convert geodetic latitudes to authalic latitudes.

Description This projection preserves the area of individual polygons while simultaneously maintaining a true sense of direction from the center. Projection method Planar, projected from any point on the globe.
Point of tangency A single point, located anywhere, specified by longitude and latitude. Linear graticules All aspects—the central meridian defining the point of tangency.
Equatorial aspect—the equator. Polar aspect—all meridians. Area Equal area.

Direction True direction radiating from the central point. Distance True at center.
Limitations The data must be less than a hemisphere in extent. Uses and applications Population density area.
Political boundaries area. Oceanic mapping for energy, minerals, geology, and tectonics direction.
This projection can handle large areas; thus it is used for displaying entire continents and polar regions. Oblique aspect: North America, Europe, and Asia. Lambert Azimuthal Auxiliary Sphere Desktop version 9.
