longitude
含义: The angular distance of a place east or west of the Prime Meridian at Greenwich, measured in degrees.
Longitude lines run vertically on maps from pole to pole. The Prime Meridian (0 degrees longitude) passes through the Royal Observatory at Greenwich, London — a fact that reflects Britain's historical dominance in navigation and cartography. Determining longitude at sea was one of the great scientific challenges of the 18th century, eventually solved by John Harrison's marine chronometer. Longitude is essential for accurate navigation, timekeeping, and mapping.
