Miller cylindrical projection
Cylindrical compromise map projection / From Wikipedia, the free encyclopedia
The Miller cylindrical projection is a modified Mercator projection, proposed by Osborn Maitland Miller in 1942. The latitude is scaled by a factor of 4⁄5, projected according to Mercator, and then the result is multiplied by 5⁄4 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]
