The planet is certainly a place of impressive magnitude. It houses natural settings, flora and fauna of exuberant beauty, which vary throughout it. The human, since he noticed the very different characteristics of each species, became interested and began to explore, classifying them one by one. This is how much of the sciences that we know today were born among these, highlights geography, a discipline in charge of the study of the earth's surface, from different perspectives. With the help of geography, it is possible to locate certain points on Earth with great accuracy, also counting on the distinctive features of the area.
This is the main function of geographic coordinates, a system that uses numbers, letters or symbols to determine an exact point on the surface of the Earth. These are born as an adaptation to the geometric coordinate system, applied in mathematics, which has the same purpose of locating a point or a geometric body in a given plane. However, in geography, other elements are used, such as meridians (great circles that have the same diameter as the Earth's sphere and that determine the location of the poles) and parallels (intersections parallel to the equator).
To have specific geographical coordinates, it is necessary to know the latitude, an angle that is measured from the center of the earth and the equatorial line, the longitude, the angle that the reference meridian (generally Greenwich Mean) with the meridian that passes through a specific point, in addition to the altitude, data that is calculated with the help of a representative sphere of the Earth.
