Longitude lines are perpendicular to and latitude lines are parallel to the Equator. 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 ...
A navigation system on an oil tanker. Navigation [1] is a field of study that focuses on the process of monitoring and controlling the movement of a craft or vehicle from one place to another. [2] The field of navigation includes four general categories: land navigation, [3] marine navigation, aeronautic navigation, and space navigation.
Latitude and longitude coordinates on maps are usually expressed in degrees. In the given forms of the formulae below, one or more values must be expressed in the specified units to obtain the correct result. Where geographic coordinates are used as the argument of a trigonometric function, the values may be expressed in any angular units ...
Longitude ( / ˈlɒndʒɪtjuːd /, AU and UK also / ˈlɒŋɡɪ -/) [1] [2] is a geographic coordinate that specifies the east – west position of a point on the surface of the Earth, or another celestial body. It is an angular measurement, usually expressed in degrees and denoted by the Greek letter lambda (λ). Meridians are imaginary ...
The following graph illustrates the variation of both a degree of latitude and a degree of longitude with latitude. The definition of geodetic latitude (ϕ) and geocentric latitude (θ). Auxiliary latitudes. There are six auxiliary latitudes that have applications to special problems in geodesy, geophysics and the theory of map projections:
Middle East location map2.svg. Module:Location map/data/Middle East2 is a location map definition used to overlay markers and labels on an equirectangular projection map of Middle East. The markers are placed by latitude and longitude coordinates on the default map or a similar map image.
Chart of lunar maria with lines of longitude and latitude. The prime meridian is the centre of the near side of the Moon. A planetary coordinate system (also referred to as planetographic, planetodetic, or planetocentric) is a generalization of the geographic, geodetic, and the geocentric coordinate systems for planets other than Earth.
Address geocoding, or simply geocoding, is the process of taking a text-based description of a location, such as an address or the name of a place, and returning geographic coordinates, frequently latitude/longitude pair, to identify a location on the Earth's surface. [1] Reverse geocoding, on the other hand, converts geographic coordinates to ...
