The Miller cylindrical projection is a modified Mercator projection, proposed by Osborn Maitland Miller (1897–1979) in 1942. The parallels of latitude are scaled by a factor of 2/5, projected according to Mercator, and then the result is multiplied by 5/4 to retain scale along the equator. Hence:
where λ is the longitude from the central meridian of the projection, and φ is the latitude.

Waterman "Butterfly" World Map Projection
The Waterman "Butterfly" World Map Projection was created by Steve Waterman and published in 1996. It is an octahedral transformation of a globe, reviving the Butterfly Map principle first developed by Bernard J.S. Cahill (1866-1944) in 1909. Whereas Cahill's approach was that of an architect,... -
Lambert cylindrical equal-area projection
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. The... -
Transverse Mercator projection
The transverse Mercator projection is an adaptation of the Mercator projection. Both projections are cylindrical and conformal. However, in the transverse Mercator, the cylinder is rotated 90° (transverse) relative to the equator so that the projected surface is aligned to a central meridian rather... -
Craig retroazimuthal projection
The Craig retroazimuthal map projection was created by James Ireland Craig in 1909. It is a cylindrical projection preserving the direction from any place to another, predetermined place while avoiding some of the bizarre distortion of the Hammer retroazimuthal projection. It is sometimes known as... -
Mercator projection
The Mercator projection is a cylindrical map projection presented by the Flemish geographer and cartographer Gerardus Mercator, in 1569. It became the standard map projection for nautical purposes because of its ability to represent lines of constant course, known as rhumb lines or loxodromes, as... -
Space-oblique Mercator projection
Space-oblique Mercator projection is a map projection. The Space-oblique Mercator projection (SOM) was developed by John P. Snyder, Alden Partridge Colvocoresses and John L. Junkins in 1976. Snyder had an interest in maps, originating back to his childhood and his regularly attended cartography... -
Polyconic projection
A polyconic projection is a conical map projection. The projection stems from "rolling" a cone tangent to the Earth at all parallels of latitude, instead of a single cone in a normal conic projection. Each parallel is a circular arc of true scale. The scale is also true on the central meridian of... -
Robinson projection
The Robinson projection is a map projection of a world map, which shows the entire world at once. It was specifically created in an attempt to find a good compromise to the problem of readily showing the whole globe as a flat image. The Robinson projection is an accomplishment of Arthur H. Robinson... -
Behrmann projection
The Behrmann Projection is a cylindrical map projection. This is an orthographic projection onto a cylinder secant at the 30º parallels. It is equal-area, but distortion of shape increases with distance from the standard parallels. Scale is true along the standard parallels and constant between two... -
