A Mercator map can therefore never fully show the polar areas (but see Uses below for applications of the oblique and transverse Mercator projections). The Mercator projection is often compared to and confused with the central cylindrical projection , which is the result of projecting points from the sphere onto a tangent cylinder along ...
Gerardus Mercator (/ dʒ ɪ ˈ r ɑːr d ə s m ɜːr ˈ k eɪ t ər /; [a] [b] [c] 5 March 1512 – 2 December 1594) [d] was a Flemish geographer, cosmographer and cartographer.He is most renowned for creating the 1569 world map based on a new projection which represented sailing courses of constant bearing (rhumb lines) as straight lines—an innovation that is still employed in nautical charts.
Mercator's 1569 map was a large planisphere, [3] i.e. a projection of the spherical Earth onto the plane. It was printed in eighteen separate sheets from copper plates engraved by Mercator himself. [4]
Web Mercator: Cylindrical Compromise Google: Variant of Mercator that ignores Earth's ellipticity for fast calculation, and clips latitudes to ~85.05° for square presentation. De facto standard for Web mapping applications. 1822 Gauss–Krüger = Gauss conformal = (ellipsoidal) transverse Mercator: Cylindrical Conformal Carl Friedrich Gauss
Web Mercator is a spherical Mercator projection, and so it has the same properties as a spherical Mercator: north is up everywhere, meridians are equally spaced vertical lines, angles are locally correct (assuming spherical coordinates), and areas inflate with distance from the equator such that the polar regions are grossly exaggerated.

oblique Mercator projection. The oblique Mercator map projection is an adaptation of the standard Mercator projection. The oblique version is sometimes used in national mapping systems. When paired with a suitable geodetic datum, the oblique Mercator delivers high accuracy in zones less than a few degrees in arbitrary directional extent.
Mercator projection (conformal cylindrical projection) Mercator projection of normal aspect (Every rhumb line is drawn as a straight line on the map.) Transverse Mercator projection.
