Basic Guide To 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).

Currently still using the classification and structure of it. Its first version contained 70 map (56 in Europe, 10 in Asia and Africa and one from each continent). He made a selection of best map available, which redrew for a uniform edition of his form, and established a logical sequence of map: world map, Europe, Asia, Africa, New World. It also included a list of names of authors of map. This atlas was a great success, especially for its size and shape; was published in several languages, and he stopped not updated and improved in 1612. In 1575 he was appointed geographer Ortelius Philip II, a position that allowed him access to knowledge accumulated by Portuguese and Spanish explorers.

The universe in general (and the Solar System in particular) certainly offer new grounds for this work having origins immemorial. Using techniques based on satellite photography has made it possible not only to know the exact contours of country, a continent, or the world, but also ethnological, historical, statistical, hydrographic, terrain, geomorphological, geological, and economic factors that lead men to their wider environment, the planet we live knowledge.

Tours of Venetians and Genoese within Africa, and large runs of Portuguese and Spanish along the coast of continent-and later the American-gave a new boost to mapping. In Mexico, indigenous leaders, as Hernan Cortes, had geographical map drawn on paper of maguey and skins, and cotton fabrics, sisal and palm, in which he drew with vegetable colors and sometimes were given a finish with varnish.

On the world map Mercator, Cartesian coordinates referred to parallels are parallel to x-axis straight, the Ecuador represented by said shaft, and the meridians are parallel to y-axis lines, the meridian represented by said shaft; the poles are not representable in map. The Mercator map projection is thus a direct rectangular cylindrical projection in which the parallels are lines that preserve distances.

The modulus of linear deformation increases with latitude toward the north pole or south pole, being infinite in both poles. A parallel equidistant in terrestrial sphere correspond well, on map, increasingly spaced lines.

Rhumb lines on Earth (lines intersect all meridians as a constant angle) are plotted on this map by straight. Only the Mercator projection has this property. Using this mapping is usually in marine navigation, because to find the route angle simple graphics procedures. However, in this map the scale is very fast, especially at high latitudes, so you should always give the Mercator map scale for a given parallel of reference, which may be the Ecuador or to average parallel map.

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.).
