Prime meridian is the name of the line that marks 0 degrees of longitude. The prime meridian marks the beginning reference point for making measurements in the eastward and westward directions. Any location along the prime meridian serves as a starting point for measurements, although international consensus designates the city of Greenwich, England as the official prime meridian.Know More
Despite forming a mutual consensus appointing Greenwich as the official prime meridian, governments of countries worldwide historically disagreed on the actual location marking the prime meridian. Any point on the line of 0 degrees longitude qualifies unofficially as a prime meridian. Lack of consensus on a true prime meridian posed problems for cartographers, navigators and city officials.
In 1884, representatives from various countries convened at the Royal Observatory in Greenwich, England. They agreed on forming a standard line of prime meridian; the center ran through the middle of the Royal Observatory, previously a working scientific facility. In addition to marking 0 degrees east and west, the prime meridian establishes Universal Coordinated Time, or UTC. Countries worldwide use UTC to set regional time zones within their borders. Additionally, the prime meridian divides the world, along with the International Date Line, into the Eastern and Western Hemispheres.Learn more about Maps & Cartography

Lines of longitude are also known as meridians. Lines of longitude and latitude create a grid pattern on the globe for navigation. The Earth is split into 360 lines of longitude. The Prime Meridian runs through Greenwich, England, while the equator serves as the zeroth pace for latitude.Full Answer >
The Equator is located at 0 degrees latitude. The Equator is an imaginary line that runs around the center of the Earth, and it is its widest point. It separates the Earth into the Northern and Southern Hemispheres.Full Answer >
The 0 degrees latitude line is called the equator. Latitude lines are parallel lines that are measured in 1 degree increments north and south of the equator. Latitude lines are measured either 0 to 90 degrees north or 0 to 90 degrees south of the equator.Full Answer >
