Taking A Look At Adc Maps

By Christa Jarvis


Map is a graphical representation of measuring and portion generally on a two dimensional surface area, but it can also be spherical as in globes. Map has the metric properties means that it must be possible to take measurements of distances, angles or surfaces on it and get a result that may be related to same measurements made in real world (adc maps).

Started in order to know their world, and supported primarily on philosophical theories, map today are an important source of information and a large part of human activity is related in one way or another with mapping. Currently you have concerns (and need) to continue the never-ending mapping work.

After the work of Ptolemy, for many centuries virtually stagnated mapping, so that seafarers navigated using makeshift map, until the discovery of compass enabled first portulanos develop. These map, resulting from experience, include those of Italian, Catalan, Portuguese, Venetian, French, and especially Mallorcan schools.

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.

To meet these demands, the cartographer can create multiple "levels of reading." At all times we should consider the simplification techniques, based on colors or symbols, bearing in mind that in a plane close reading can get detailed information elements. The amount of information must relate proportionately to scale. The larger the space dedicated to a region, the greater the number of data elements that can bring about them.

At the time of discovery of America highlighted the great cartographers and Diego Mendez, Juan de la Cosa, Pedro and Jorge Reinel, Sebastiano Caboto, Oronteus Finaeus, Desceliers and in a very special way, Gerardus Mercator, who in 1569 first used the canevas projection. As a curious fact is that Amerigo Vespucci, who received the great honor of naming the New World, was actually a prominent cartographer but not outstanding, and the perhaps undeserved honor that was done, was because an editor who published first map of new lands, pointed and the name was popularized in an irreversible way.

Maybe they have not passed a single arrow indicating direction between two points, but still can considered as a first cartographic sketch. The natives of Marshall Islands and elaborated prehistoric proto-map on lattices of palm shells, representing "nautical charts" and indicating the curvature of wave fronts. Also noteworthy as background, cards made by primitive Eskimos on the hydrography of regions they inhabited.

The oldest known map are a Babylonian tablets from about 5000 years ago. However, the first science-based map come from Greece, and are based on trying to faithfully reproduce information given by different travelers, trying to combine this information. It states that Thales drew the first map of world in which the world is conceived as a disk floating on water. Aristotle was the first to measure the angle of inclination with respect to Ecuador, which then allows us to deduce the sphericity of Earth and even the existence of tropical and polar caps. Hipparchus (II century BC.).
