A family of map projections that includes as special cases Mollweide projection, Collignon projection, and the various cylindrical equal-area projections. 1932 Wagner VI: Pseudocylindrical Compromise K. H. Wagner: Equivalent to Kavrayskiy VII vertically compressed by a factor of /. c. 1865: Collignon
Equal-area and equidistant projections appear in the National Atlas. Other projections, such as the Miller Cylindrical and the Van der Grinten, are chosen occasionally for convenience, sometimes making use of existing base maps prepared by others. Some projections treat the Earth only as a sphere, others as either ellipsoid or sphere.

The Equal Earth map projection is an equal-area pseudocylindrical global map projection, invented by Bojan Šavrič, Bernhard Jenny, and Tom Patterson in 2018. It is inspired by the widely used Robinson projection, but unlike the Robinson projection, retains the relative size of areas. The projection equations are simple to implement and fast ...
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.

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 ...
{{Map projections | state = expanded}} will show the template expanded, i.e. fully visible. {{Map projections | state = autocollapse}} will show the template autocollapsed, i.e. if there is another collapsible item on the page (a navbox, sidebar, or table with the collapsible attribute), it is hidden apart from its title bar, but if not, it is ...
The Natural Earth projection is a pseudocylindrical map projection designed by Tom Patterson and introduced in 2008. [1] It is neither conformal nor equal-area , but a compromise between the two. In its original presentation, the projection's origin is described as "The impetus for creating the Natural Earth projection was dissatisfaction with ...
