  2. Geographic coordinate system - Wikipedia

    en.wikipedia.org/wiki/Geographic_coordinate_system

    t. e. A geographic coordinate system (GCS) is a spherical or geodetic coordinate system for measuring and communicating positions directly on 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.

  3. Cartesian coordinate system - Wikipedia

    en.wikipedia.org/wiki/Cartesian_coordinate_system

    Cartesian coordinate system with a circle of radius 2 centered at the origin marked in red. The equation of a circle is (x − a)2 + (y − b)2 = r2 where a and b are the coordinates of the center (a, b) and r is the radius. Cartesian coordinates are named for René Descartes, whose invention of them in the 17th century revolutionized ...

  4. Earth-centered, Earth-fixed coordinate system - Wikipedia

    en.wikipedia.org/wiki/Earth-centered,_Earth...

    The Earth-centered, Earth-fixed coordinate system (acronym ECEF), also known as the geocentric coordinate system, is a cartesian spatial reference system that represents locations in the vicinity of the Earth (including its surface, interior, atmosphere, and surrounding outer space) as X, Y, and Z measurements from its center of mass. [1][2 ...

  5. X&Y - Wikipedia

    en.wikipedia.org/wiki/X&Y

    X&Y. X&Y is the third studio album by British band Coldplay, released on 6 June 2005 by Parlophone in the United Kingdom, and a day later by Capitol Records in the United States. Produced by Coldplay and producer Danton Supple, it is noted for its troubled and urgent development, as well as manager and creative director Phil Harvey 's brief ...

  6. Coordinate system - Wikipedia

    en.wikipedia.org/wiki/Coordinate_system

    Coordinate system. The spherical coordinate system is commonly used in physics. It assigns three numbers (known as coordinates) to every point in Euclidean space: radial distance r, polar angle θ (theta), and azimuthal angle φ (phi). The symbol ρ (rho) is often used instead of r.

  7. Cardinal direction - Wikipedia

    en.wikipedia.org/wiki/Cardinal_direction

    Cardinal directions or cardinal points may sometimes be extended to include vertical position (elevation, altitude, depth): north and south, east and west, up and down; or mathematically the six directions of the x-, y-, and z-axes in three-dimensional Cartesian coordinates. Topographic maps include elevation, typically via contour lines.

  8. Projected coordinate system - Wikipedia

    en.wikipedia.org/wiki/Projected_coordinate_system

    Geodesy. A projected coordinate system – also called a projected coordinate reference system, planar coordinate system, or grid reference system – is a type of spatial reference system that represents locations on Earth using Cartesian coordinates (x, y) on a planar surface created by a particular map projection. [1]

  9. Pokémon X and Y - Wikipedia

    en.wikipedia.org/wiki/Pokémon_X_and_Y

    Pokémon X and Pokémon Y are 2013 role-playing video games developed by Game Freak and published by The Pokémon Company and Nintendo for the Nintendo 3DS. [1] They are the first installments in the sixth generation of the main Pokémon game series. First announced in January 2013 by Nintendo president Satoru Iwata through a Nintendo Direct ...
