Coordinates [verified] - Meridian

For centuries, the lack of a standardized "zero meridian" was a logistical nightmare. Sailors and cartographers used various reference points based on their home nations; the French used Paris, the Spanish used Cadiz, and the British used Greenwich. It was not until the International Meridian Conference of 1884 that Greenwich, London, was largely adopted as the Prime Meridian (0° longitude).

The Earth rotates 360° every 24 hours. If you divide 360 by 24, you get 15. This means that every represents one hour of time difference. This is why "Greenwich Mean Time" (GMT) is the baseline for the world's clocks. 2. Global Navigation meridian coordinates

It sounds like you're asking about — likely in the context of astronomy , geodesy , or mapping . The Earth rotates 360° every 24 hours

At its simplest, a is an imaginary semicircle that runs from the North Pole to the South Pole. Every point on Earth’s surface sits on one of these 360 lines (one for each degree of longitude). When we speak of "meridian coordinates," we are primarily talking about longitude —the angular distance, measured in degrees, east or west of a specific reference line.
