: The distance between two meridians is widest at the equator (about 111 kilometers or 69 miles) and shrinks to zero at the poles. The Prime Meridian: The Universal Starting Point meridian coordinates

The standard system divides the Earth's 360-degree rotation into specific units: Are there you want to emphasize

Longitude is an angular measurement. It represents the angle between the plane of the Prime Meridian and the plane of the meridian passing through any specific point on Earth, measured from the center of the globe. Degrees, Minutes, and Seconds (DMS) It represents the angle between the plane of

It wasn't until the Bronze Figure of the Song Dynasty (1026 CE) that the first "coordinate mapping" occurred. Imperial physician Wang Weiyi cast two life-sized bronze statues engraved with 354 meridian points. Holes were drilled at the exact coordinates, and the statues were coated in wax. Students had to insert a needle into the wax to reach a pool of mercury inside. If the was miscalculated by even a millimeter, the needle would hit solid bronze.

Modern computational systems, including Global Positioning System (GPS) algorithms and Geographic Information Systems (GIS), replace the DMS system with for simpler calculations.
