Cylindrical equal-area projection with standard parallel at the equator and an aspect ratio of π (3.14). 1910 Behrmann: Cylindrical Equal-area Walter Behrmann: Cylindrical equal-area projection with standard parallels at 30°N/S and an aspect ratio of (3/4)π ≈ 2.356. 2002 Hobo–Dyer: Cylindrical Equal-area Mick Dyer
Mollweide projection of the world The Mollweide projection with Tissot's indicatrix of deformation. The Mollweide projection is an equal-area, pseudocylindrical map projection generally used for maps of the world or celestial sphere. It is also known as the Babinet projection, homalographic projection, homolographic projection, and elliptical ...
The Robinson projection is an example of a pseudocylindrical projection. One of Robinson's most notable accomplishments is the Robinson projection . In 1961, Rand McNally asked Robinson to choose a projection for use as a world map that, among other criteria, was uninterrupted, [ 13 ] had limited distortion , and was pleasing to the eye of ...
Def. "Pseudo-cylindrical projections" are result of efforts to minimize the distortion of the polar regions of the cylindrical projections by bending the meridians toward the center of the map as a funtion of longitude while maintaining the cylindrical characteristic of parallel parallels.

The various cylindrical projections are distinguished from each other solely by their north-south stretching (where latitude is given by φ): The only normal cylindrical projections that preserve area have a north-south compression precisely the reciprocal of east-west stretching (cos φ). This divides north-south distances by a factor equal to ...
Eckert IV projection of the world. Eckert IV projection with Tissot's indicatrices of distortion. The Eckert IV projection is an equal-area pseudocylindrical map projection. The length of the polar lines is half that of the equator, and lines of longitude are semiellipses, or portions of ellipses. It was first described by Max Eckert in 1906 as ...

Eckert VI projection of the world. The Eckert VI projection is an equal-area pseudocylindrical map projection. The length of polar line is half that of the equator, and lines of longitude are sinusoids. It was first described by Max Eckert in 1906 as one of a series of three pairs of pseudocylindrical projections. In each pair, the meridians ...
