Coordonate geografice. O reprezentare a liniilor de latitudine care sunt orizontale și a celor de longitudine, verticale. Sistemul de coordonate geografice pe glob. Sistemul de coordonate geografice este un sistem de referință care utilizează coordonatele unghiulare, latitudine ( nordică sau sudică) și longitudine ( estică și vestică ...
A geographic coordinate system ( GCS) is a spherical or geodetic coordinate system for measuring and communicating positions directly on the Earth as latitude and longitude. [1] It is the simplest, oldest and most widely used of the various spatial reference systems that are in use, and forms the basis for most others.
• A coordinate system is a standardized method for assigning codes to locations so that locations can be found using the codes alone. • Standardized coordinate systems use absolute locations. • In a coordinate system, the x-direction value is the easting and the y-direction value is the northing. Most systems make both values positive.

May 21, 2023 · Coordinate systems are frameworks that are used to define unique positions. For instance, in geometry, we use x (horizontal) and y (vertical) coordinates to define points on a two-dimensional plane. The coordinate system used to define locations on the three-dimensional earth is the geographic coordinate system (GCS), based on a sphere or spheroid.

Geographic coordinate system. A geographical coordinate system is a coordinate system. This means that every place can be specified by three sets of three numbers, called coordinates. A full circle can be divided into 360 degrees (or 360°); this was first done by the Babylonians; Ancient Greeks, like Ptolemy later extended the theory.
To quote from the Wikipedia page of the WGS 84: The WGS 84 datum surface is an oblate spheroid with equatorial radius a = 6378137 m at the equator and flattening f = 1/298.257223563. The refined value of the WGS 84 gravitational constant (mass of Earth's atmosphere included) is GM = 3986004.418×108 m3/s2.
