In cartography, the Lambert cylindrical equal-area projection, Lambert cylindrical projection, or cylindrical equal-area projection is a cylindrical, equal area map projection. The invention of this projection is attributed to the Alsatian mathematician Johann Heinrich Lambert in 1772.[1]

The projection is:

x = ( \lambda - \lambda_0 ) \cos \phi_0\,
y = \sin \phi / \cos \phi_0\,

where \phi\, is the latitude, \lambda\, is the longitude, \lambda_0\, is the central meridian, and \phi_0\, is the standard latitude[2].
