All of the other 28 points are written only in Dutch, confirming Mercator's wish that his map would be put to practical use by mariners. Within the map Mercator embellishes the open seas with fleets of ships, sea creatures, of which one is a dolphin, and a striking god-like figure which may be Triton. The unknown continental interiors are ...
For example, a Mercator map printed in a book might have an equatorial width of 13.4 cm corresponding to a globe radius of 2.13 cm and an RF of approximately 1 / 300M (M is used as an abbreviation for 1,000,000 in writing an RF) whereas Mercator's original 1569 map has a width of 198 cm corresponding to a globe radius of 31.5 cm and an ...
Lines of constant bearing (rhumb lines) are straight, aiding navigation. Areas inflate with latitude, becoming so extreme that the map cannot show the poles. 2005 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 ...
Mercator Nova et Aucta Orbis Terrae Descriptio, 1569. High res image. Flemish geographer and cartographer Gerardus Mercator world map of 1569 introduced a cylindrical map projection that became the standard map projection known as the Mercator projection. It was a large planisphere measuring 202 by 124 cm (80 by 49 in), printed in eighteen ...
Web Mercator, Google Web Mercator, Spherical Mercator, WGS 84 Web Mercator [1] or WGS 84/Pseudo-Mercator is a variant of the Mercator map projection and is the de facto standard for Web mapping applications. It rose to prominence when Google Maps adopted it in 2005. [2] It is used by virtually all major online map providers, including Google ...
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.
Glueing many maps together restores roundness. To make a new sheet from many maps or to change the center, the body must be re-projected. Seamless online maps can be very large Mercator projections, so that any place can become the map's center, then the map remains conformal. However, it is difficult to compare lengths or areas of two far-off ...
