formulaeaccuracyTwo sets of formulae, simpler than those in current use but capable of considerable accuracy, are presented. One set is suitable for use at distances of up to 500 km from the central meridian in all latitudes up to about 74°; the other, the polar form, gives accurate ...
TheWeb Mercator projectionuses a modified version of the Mercator projection and has become a default map projection for web mapping. The major difference between this projection is that it uses a spherical formula at all scales. Whereas the Mercator projection uses a vertically-orientedcylinder proje...
Also If theres a formula to calculate the Mercator projection it should be possible to Change this formula a bit to remove the distortion/stretching or am i wrong ? david-rhodes commented on Dec 2, 2017 david-rhodes on Dec 2, 2017 Why can't you adjust the size of the tiles? UnityTil...

Thus, the formula for the positions of the parallels in a Mercator projection can be looked up in a table of integrals: _n / | 1 1 n -1 | ---, dx = ln( --- + tan(n) ) = ln( tan( 45° + - ) ) = gd (n) | cos(x) cos...
Oblique Mercator ProjectionThe oblique Mercator (OM) projection for which the basic formulae were originally developed by Brigadier M. Hotine is used where the area of interest is oblong, and the longer axis through the territory is skewed with respect to the meridians (Hotine, 1946–1947)....

Faced with the need for repeated calculation of Transverse Mercator Projections and their inverses on small computers an acceptable simplification of the formulae was sought. In the event a geometrical projection close to gnomic was found giving very accurate results in both Great Britain and Ireland...
