Longitude
Longitude ( / ˈ l ɒ n dʒ ɪ tj uː d / , AU and UK also / ˈ l ɒ ŋ ɡ ɪ -/ ), [1] [2] 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 pole to 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 0° 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 through the Prime Meridian and a plane through both poles and the location in question. (This forms a right-handed coordinate system with the z -axis (right hand thumb) pointing from the Earth's center toward the North Pole and the x -axis (right hand index finger) extending from the Earth's center through the Equator at the Prime Meridian.)

Longitude is the angular distance of a point's meridian from the Prime (Greenwich) Meridian. It is usually expressed in degrees, minutes, and seconds. Lines of longitude are often referred to as meridians ( pronounced /ˈlɒndʒɨtjuːd/ (deprecated template) or /ˈlɒŋɡɨtjuːd/ ), [1] identified by the Greek letter lambda (λ), is the geographic coordinate most commonly used in cartography and global navigation for east-west measurement. Constant longitude is represented by lines running from north to south. The line of longitude ( meridian ) that passes through the Royal Observatory, Greenwich , in England, establishes the meaning of zero degrees of longitude, or the Prime Meridian . Any other longitude is identified by the east-west angle, referenced to the center of the Earth as vertex, between the intersections with the Equator of the meridian through the location in question and the Prime Meridian. A location's position along a meridian is given by its latitude , which is identified by the north-south angle between the local vertical and the plane of the Equator. |

Longitude , sometimes denoted by the Greek letter λ (lambda) , [1] [2] describes the location of a place on Earth east or west of a north-south line called the Prime Meridian . Longitude is given as an angular measurement ranging from 0° at the Prime Meridian to +180° eastward and −180° westward. Unlike latitude , which has the equator as a natural starting position, there is no natural starting position for longitude. Therefore, a reference meridian had to be chosen. While British cartographers had long used the Greenwich meridian in London , other references were used elsewhere, including: El Hierro , Rome , Copenhagen , Jerusalem , Saint Petersburg , Pisa , Paris , Philadelphia and Washington . In 1884 , the International Meridian Conference adopted the Greenwich meridian as the universal prime meridian or zero point of longitude . |

Longitude describes the location of a place east or west of a north-south line called the prime meridian . Longitude is given in an angular measurement ranging from 0° at the Prime Meridian to plus or minus 180°. Unlike latitude which has the equator as a natural starting position, there is no natural starting position for longitude. Therefore an arbitrary starting position was chosen that passed through Greenwich in London, England. |
