  2. Null Island - Wikipedia

    en.wikipedia.org/wiki/Null_Island

    Null Island is the location at zero degrees latitude and zero degrees longitude), i.e., where the prime meridian and the equator intersect. Since there is no landmass located at these coordinates, it is not an actual island. The name is often used in mapping software as a placeholder to help find and correct database entries that have ...

  3. Equator - Wikipedia

    en.wikipedia.org/wiki/Equator

    Road sign marking the equator near Nanyuki, Kenya. The latitude of the Earth's equator is, by definition, 0° (zero degrees) of arc.The equator is one of the five notable circles of latitude on Earth; the other four are the two polar circles (the Arctic Circle and the Antarctic Circle) and the two tropical circles (the Tropic of Cancer and the Tropic of Capricorn).

  4. List of circles of latitude - Wikipedia

    en.wikipedia.org/wiki/List_of_circles_of_latitude

    The equator, a circle of latitude that divides a spheroid, such as Earth, into the northern and southern hemispheres. On Earth, it is an imaginary line located at 0 degrees latitude . 0°

  5. Geodetic coordinates - Wikipedia

    en.wikipedia.org/wiki/Geodetic_coordinates

    Longitude measures the rotational angle between the zero meridian and the measured point. By convention for the Earth, Moon and Sun, it is expressed in degrees ranging from −180° to +180°. For other bodies a range of 0° to 360° is used. For this purpose, it is necessary to identify a zero meridian, which for Earth is usually the Prime ...

  6. Prime meridian - Wikipedia

    en.wikipedia.org/wiki/Prime_meridian

    A prime meridian is an arbitrarily chosen meridian (a line of longitude) in a geographic coordinate system at which longitude is defined to be 0°. Together, a prime meridian and its anti-meridian (the 180th meridian in a 360°-system) form a great circle.

  7. Longitude - Wikipedia

    en.wikipedia.org/wiki/Longitude

    A geographical mile is defined to be the length of one minute of arc along the equator (one equatorial minute of longitude) therefore a degree of longitude along the equator is exactly 60 geographical miles or 111.3 kilometers, as there are 60 minutes in a degree. The length of 1 minute of longitude along the equator is 1 geographical mile or 1 ...

  8. 0° - Wikipedia

    en.wikipedia.org/wiki/0°

    0° or 0 degrees may refer to: Longitude: the prime meridian on any planet or moon For most of the 20th century on Earth, the prime meridian (Greenwich) IERS Reference Meridian, the modern reference meridian for time and global navigation on Earth; Latitude: the equator; freezing point of water (Celsius)

  9. Geographic coordinate system - Wikipedia

    en.wikipedia.org/wiki/Geographic_coordinate_system

    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 type of the various spatial reference systems that are in use, and forms the basis for most others.
