The location is used by mapping systems to trap errors. [8] Such errors arise, for example, where an image artifact is erroneously associated to the location by software which cannot attribute a geoposition, and instead associates a latitude and longitude of "Null,Null" or "0,0". [11]
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).
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°
This is a list of places on land below mean sea level.. Places artificially created such as tunnels, mines, basements, and dug holes, or places under water, or existing temporarily as a result of ebbing of sea tide etc., are not included.
Latitude is given as an angle that ranges from −90° at the south pole to 90° at the north pole, with 0° at the Equator. Lines of constant latitude, or parallels, run east–west as circles parallel to the equator. Latitude and longitude are used together as a coordinate pair to specify a location on the surface of the Earth.
The centre of the standard geographic model as viewed on a traditional world map is the point 0°, 0° (the coordinates of zero degrees latitude by zero degrees longitude), which is located in the Atlantic Ocean about 614 km (382 mi) south of Accra, Ghana, in the Gulf of Guinea.

A geodetic datum or geodetic system (also: geodetic reference datum, geodetic reference system, or geodetic reference frame, or terrestrial reference frame) is a global datum reference or reference frame for unambiguously representing the position of locations on Earth by means of either geodetic coordinates (and related vertical coordinates) or geocentric coordinates.
