Miller cylindrical projection
Encyclopedia
The Miller cylindrical projection is a modified Mercator projection
, proposed by Osborn Maitland Miller (1897–1979) 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. Hence:
where λ is the longitude from the central meridian of the projection, and
is the latitude. Meridians are thus about 0.733 the length of the equator.
In GIS applications, this projection is known as: "EPSG:54003 - World Miller Cylindrical"
Mercator projection
The Mercator projection is a cylindrical map projection presented by the Belgian 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...
