Longitude

Longitude (d or d, British also d), 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). Points with the same longitude lie in lines running from the North Pole to the South Pole. By convention, on....

Longitude

An east/west angular measurement of position in relation to the Prime Meridian. The angle between the two great circles, one being the Prime (or Greenwich) Meridian and the other a meridian passing through the point of interest. (A great circle that passes through the north and south poles, and hence contains the earth's rotation axis.)

Longitude

In geography, Longitude is the the distance of a place due east or west from a meridian taken as a starting-point, this distance being measured along the equator or a parallel of latitude; in other words, it is the angle between the meridian plane of one place and some fixed meridian plane. Longitudes are generally reckoned from the meridian of Gre...
