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.
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 ...
To complete the map collection quickly, Rumold added his own world map from 1587 and had four maps of the continents from his father's large world map from 1569 copied by his nephews Gerardus Mercator junior and Michael Mercator, sons of Arnold Mercator. The title page was also an emergency solution: it is the title of the Ptolemy edition of ...
Edward Wright (baptised 8 October 1561; died November 1615) was an English mathematician and cartographer noted for his book Certaine Errors in Navigation (1599; 2nd ed., 1610), which for the first time explained the mathematical basis of the Mercator projection by building on the works of Pedro Nunes, and set out a reference table giving the linear scale multiplication factor as a function of ...
His map covers the entire world in a double hemisphere projection. This map follows shortly after the explorations of Captain Cook in the Arctic and Pacific Northwest, so the general outline of North America is known. However, when this map was made, few inland expeditions had extended westward beyond the Mississippi River. [55]
World map made by Rumold Mercator in 1587, using two equatorial aspects of the stereographic projection. The stereographic projection was likely known in its polar aspect to the ancient Egyptians , though its invention is often credited to Hipparchus , who was the first Greek to use it.
The map encompasses the eastern coast of North America, the entire Central and South America and parts of the western coasts of Europe and Africa. Americae Sive Quartae Orbis Partis Nova Et Exactissima Descriptio is the earliest scale wall map of the New World and the first to use the name "California". [1]
