Definitions:

(1)
(longitude) a measure of east/west (relative to the Prime Meridian) on the earthLines of longitude are the imaginary lines that run from the North Pole to the South Pole. They are sometimes called meridians. Unlike latitude, which measures north–south, longitude measures how far east or west a place is on Earth.
By international agreement, the zero line of longitude (0°) is the prime meridian, which passes through Greenwich, England. Longitudes go up to 180° east and 180° west. Used together with latitude, longitude lets you give an exact position for any point on Earth. - (2) (meaning too rare to warrant focus)
