Miller cylindrical projection

From Wikipedia
A Miller projection of the Earth.
Miller projection with 1,000 km indicatrices of distortion.

The Miller cylindrical projection is a modified Mercator projection, proposed by Osborn Maitland Miller in 1942. The latitude is scaled by a factor of 45, projected according to Mercator, and then the result is multiplied by 54 to retain scale along the equator. [1] Hence:

or inversely,

where λ is the longitude from the central meridian of the projection, and φ is the latitude. [2] Meridians are thus about 0.733 the length of the equator.

In GIS applications, this projection is known as: "ESRI:54003 - World Miller Cylindrical" [3]

Compact Miller projection is similar to Miller but spacing between parallels stops growing after 55 degrees. [4]
