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.

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 ...
Tobler hyperelliptical projection of the world; α = 0, γ = 1.18314, k = 2.5 The Tobler hyperelliptical projection with Tissot's indicatrix of deformation; α = 0, k = 3. The Tobler hyperelliptical projection is a family of equal-area pseudocylindrical projections that may be used for world maps.
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 ...
