Map of the Earth using a Lambert Cylindrical projection. Equator is the standard parallel.

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].
