With the exception of compression in the horizontal direction and expansion in the vertical direction, the Behrmann projection is the same as the Lambert Cylindrical Equal-area projection. These changes prevent distortion at latitudes 30° N and S instead of at the Equator.

Construction

Cylindrical

Property

Equal-area

Meridians

Straight parallel lines that are equally spaced and 0.42 the length of the Equator.

Parallels

Straight lines that are unequally spaced and farthest apart near the Equator, perpendicular to meridians.

Graticule spacing

See Meridians and Parallels. Poles are straight lines the same length as the Equator. Symmetry is present about any meridian or the Equator.

Linear scale

Scale is true along latitudes 30° N and S.

Uses

Creating world maps.
