Albers projection

Although scale and shape are not preserved, distortion is minimal between the standard parallels.

It was first described by Heinrich Christian Albers (1773-1833) in a German geography and astronomy periodical in 1805.

Some "official products" also adopted Albers projection, for example most of the maps in the National Atlas of the United States.

Coordinates from a spherical datum can be transformed into Albers equal-area conic projection coordinates with the following formulas, where

the standard parallels: where If just one of the two standard parallels of the Albers projection is placed on a pole, the result is the Lambert equal-area conic projection.
