Meridian Coordinates Now

When we look at a map or use a GPS, we often take for granted the invisible grid that helps us pinpoint our exact location on Earth. While latitude lines (parallels) circle the globe horizontally, —better known as longitude—provide the vertical framework necessary for global navigation, timekeeping, and mapping. What are Meridian Coordinates?

Locations are measured up to 180° East or 180° West of this line. The point where 180° East and 180° West meet is known as the , which roughly follows the International Date Line. How Meridian Coordinates Work

Modern mapping and urban planning rely on precise meridian data to manage infrastructure and environmental changes. meridian coordinates

It divides the Earth into the Eastern Hemisphere and the Western Hemisphere.

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 When we look at a map or use

While the concept is centuries old, meridian coordinates are more relevant today than ever:

To find a specific coordinate, you measure the angle between the Prime Meridian and your location, with the center of the Earth as the vertex. Locations are measured up to 180° East or

Every coordinate system needs a "zero" point. For latitude, the starting point is the Equator. For meridian coordinates, the world agreed upon the during the International Meridian Conference in 1884.

A meridian is an imaginary north-south line that runs along the Earth's surface from the North Pole to the South Pole. Unlike latitude lines, which are parallel to one another and vary in length, all meridians are equal in length and intersect at the poles.
