# Cylindrical Equal-Area Projection

The map projection having transformation equations

 (1) (2)

for the normal aspect, where is the longitude, is the standard longitude (horizontal center of the projection), is the latitude, and is the so-called "standard latitude."

Special cases of cylindrical equal-area projections are summarized in the following table (Maling 1993).

The inverse transformation equations for the normal aspect are

 (3) (4)

An oblique form of the cylindrical equal-area projection is given by the equations

 (5) (6)

and the inverse formulas are

 (7) (8)

A transverse form of the cylindrical equal-area projection is given by the equations

 (9) (10)

and the inverse formulas are

 (11) (12)
