PRIME MERIDIAN Meaning and Definition

1. The prime meridian is an imaginary line that serves as a reference point for measuring longitude on Earth. It is commonly defined as the line that runs from the North Pole to the South Pole and passes through the Royal Observatory in Greenwich, London, which is internationally recognized as the starting point for measuring both longitude and Greenwich Mean Time (GMT). The prime meridian divides the Earth into the Eastern Hemisphere and the Western Hemisphere.

   The concept of the prime meridian emerged from the need for a standardized reference point for navigation and cartography purposes. By establishing a single line of longitude as the starting point, it became possible for sailors, travelers, and mapmakers worldwide to determine their position in relation to this baseline. The prime meridian is conventionally assigned a value of 0 degrees longitude, and all other meridians are measured east or west from this point.

   The choice of the prime meridian was primarily based on historical reasons, with Greenwich being the location of the renowned Royal Observatory. However, the 1884 International Meridian Conference solidified this selection and established Greenwich as the standard prime meridian for the purpose of global timekeeping and geodetic measurements.

   The prime meridian plays a crucial role in defining time zones worldwide, with each meridian every 15 degrees apart corresponding to a different time zone. This significant line also helps in accurately locating and identifying positions on the Earth's surface, providing a fundamental reference for navigation, satellite positioning systems, and the creation of accurate maps.

The term "meridian" comes from the Latin word "meridianus" which means "of or belonging to midday". In astronomy and cartography, a meridian is a circle of longitude that passes through the North and South Poles, as well as a specific point on the Earth's surface.

Therefore, the term "prime meridian" refers to the meridian of highest importance or significance. It specifically refers to the meridian from which all other lines of longitude are measured and used as a reference point for determining time and coordinates on Earth. The most well-known prime meridian is the one passing through Greenwich, London, which is internationally recognized as the zero degree longitude.
