Since the dawn of navigation, humanity has sought to impose a grid upon the chaotic surface of the Earth. Among the most fundamental components of this global grid are "meridian coordinates." While the term "coordinates" usually implies the intersection of two points (latitude and longitude), meridians specifically refer to the longitudinal lines that run from the North Pole to the South Pole. These invisible arcs are not merely abstract lines on a map; they are the scaffolding of global timekeeping, the key to precise navigation, and a testament to human ingenuity in measuring the sphere we inhabit.

Furthermore, there are 8 Extraordinary Vessels (Ren Mai, Du Mai, etc.) which act as reservoirs, adding another ~50 coordinates to the master map. Since the dawn of navigation, humanity has sought
The Prime Meridian passes through the Royal Observatory in Greenwich, England. Value: It is designated as 0° longitude. Example formats that work: * Decimal degrees (DD): 41
In this example, the point is located 37 degrees, 25 minutes, and 30 seconds north of the equator, and 122 degrees, 05 minutes, and 15 seconds west of the prime meridian.
When we talk about meridian coordinates, we are measuring : the angular distance of a place east or west of a specific reference line. This distance is measured in degrees, minutes, and seconds. The Prime Meridian: The Starting Point
: Paired with latitude, they pinpoint any exact location on Earth.
