The Global Positioning System (GPS) is a space-based radionavigation system owned by the United States government and operated by the United States Air Force.

It is a global navigation satellite system that provides geolocation and time information to a GPS receiver anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites.

The GPS system operates independently of any telephonic or internet reception, though these technologies can enhance the usefulness of the GPS positioning information.

The GPS system provides critical positioning capabilities to military, civil, and commercial users around the world.

The United States government created the system, maintains it, and makes it freely accessible to anyone with a GPS receiver.

However, the US government can selectively deny access to the system, as happened to the Indian military in 1999 during the Kargil War.

The Universal Transverse Mercator (UTM) conformal projection uses a 2-dimensional Cartesian coordinate system to give locations on the surface of the Earth.

Like the traditional method of latitude and longitude, it is a horizontal position representation, i.e. it is used to identify locations on the Earth independently of vertical position.

However, it differs from that method in several respects.

In geography, latitude is a geographic coordinate that specifies the north–south position of a point on the Earth's surface.

Latitude is an angle (defined below) which ranges from 0° at the Equator to 90° (North or South) at the poles.

Lines of constant latitude, or parallels, run east–west as circles parallel to the equator.

Latitude is used together with longitude to specify the precise location of features on the surface of the Earth.

Without qualification the term latitude should be taken to be the geodetic latitude as defined in the following sections.

Also defined are six auxiliary latitudes which are used in special applications.

There is a separate article on the History of latitude measurements.

Longitude (or, Australian and British also), is a geographic coordinate that specifies the east-west position of a point on the Earth's surface.

It is an angular measurement, usually expressed in degrees and denoted by the Greek letter lambda (λ).

Meridians (lines running from the North Pole to the South Pole) connect points with the same longitude.

By convention, one of these, the Prime Meridian, which passes through the Royal Observatory, Greenwich, England, was allocated the position of zero degrees longitude.

The longitude of other places is measured as the angle east or west from the Prime Meridian, ranging from 0° at the Prime Meridian to +180° eastward and −180° westward.

Specifically, it is the angle between a plane containing the Prime Meridian and a plane containing the North Pole, South Pole and the location in question.

(This forms a right-handed coordinate system with the axis (right hand thumb) pointing from the Earth's center toward the North Pole and the axis (right hand index finger) extending from Earth's center through the equator at the Prime Meridian).

A map is a symbolic depiction emphasizing relationships between elements of some space, such as objects, regions, or themes.
