  1. Longitude

    Longitude, 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. Points with the same longitude lie in lines running from the North Pole to the South Pole. By convention, one of these, the Prime Meridian, which passes through the Royal Observatory, Greenwich, England, establishes the position of zero degrees longitude. The longitude of other places is measured as an 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 z axis pointing from the Earth's center toward the North Pole and the x axis extending from Earth's center through the equator at the Prime Meridian. A location's north-south position along a meridian is given by its latitude, which is the angle between the local vertical and the plane of the Equator.

Dictionary of Nautical Terms

  1. longitude

    Is an arc of the equator, or any parallel of latitude, contained between the meridian of a place and that of Greenwich, or any other first meridian. These arcs being similar, are expressed by the same number of degrees and miles, though the absolute distance on the earth's surface decreases as the latitude increases, for which see DEPARTURE. East longitude extends 180 degrees to the right, when looking north, and west longitude as many to the left of the first meridian.
