The Prime Meridian is an imaginary line that represents 0 degrees longitude. It serves as the starting point for measuring longitude, which is the geographic coordinate that specifies the east-west position of a point on the Earth's surface. The Prime Meridian runs from the North Pole to the South Pole and passes through the Royal Observatory in Greenwich, London, England.
It is part of the global coordinate system used for navigation and mapping, dividing the eastern and western hemispheres of the Earth. Locations east of the Prime Meridian have positive longitudes (up to 180 degrees), while those to the west have negative longitudes. The establishment of the Prime Meridian in the late 19th century provided a standard point of reference for timekeeping and navigation worldwide.
