Taking A Look At Adc Maps

By Christa Jarvis


The first mathematical conventions allowed transfer of characteristics of spherical surface to a plane, ie, made first map projection. Eratosthenes (284 -. 192 BC) established first measurements of Earth. Gets the radius of earth and from that angle the length of Earth's meridian, the (very approximate to real) earth's circumference. Between him, Ptolemy and others change the conception of Greeks on Earth is not flat, but curved (adc maps).

Ptolemy (second century AD) picked up all the knowledge of his predecessors and presents the first comprehensive overview of cartographic progress to time. He published a method on the determination of coordinates based on meridians and parallels. With the work of Ptolemy began the chance to see the world in a new way: through map.

The geographer and cartographer of German-Dutch-born Gerhard Kremer, Latin Gerhardus Mercator (1512 - 1594), born in Netherlands, studied philosophy and mathematics in his youth, soon becoming an eminent cartographer; among others, performed work for the Emperor Charles V. However, in 1540s he was accused of heresy and was imprisoned for some time. After he moved to Duisburg, in Duchy of Cleves, where many Dutch Protestants persecuted were also established.

Became internationally famous in 1554 by a large map of Europe. On a world map of 1569 used map projection system was later named after him. This is a cylindrical representation with straight and parallel and meridian circles of equal latitude, and has the advantage that the straight lines connecting two points maintain a steady course, facilitating navigation compass.

These map reproduced itineraries and specific zones. It is believed that the Spaniards added to existing map notes in Spanish, replacing the footprint of barefoot shoe to indicate the paths that could be passable on horseback. Representation of Catholic churches by crosses symbolizing ideograms and later sources, canals and aqueducts were also added.

In short, any map must include a joint synthesis as an analytical detail to further reading. The level at which these conditions are met, will also be the level of certain cartographic quality map. Looks like all primitive peoples have had some form of rudimentary mapping, expressed many times by what could be called ephemeral mapping: mere momentary lines in sand, soil or other wet items.

The system of Mercator projection, can considered the most important achievement in history of cartography, before the twentieth century, new techniques of aerial photography were imposed and subsequently from satellites. Amerigo Vespucci (1454 - 1512) was a sailor who worked in service of Portugal and the Crown of Castile; was considered the first European to understand that the lands discovered by Christopher Columbus formed a new continent.

For this reason, the cartographer Martin Waldseemuller used in his map of 1507 the name "America" as a designation for the New World. Vespucci began to draw map of their travels in Americas when installed in Seville (1508) in service of King Ferdinand. Both Solis, Pinzon, Juan de la Cosa and Vespucci contributed their expeditions to path of early map it is known on the American continent.
