Geographical coordinate system

The geographical coordinate system is a way to pinpoint locations on Earth using two numbers: latitude and longitude. Latitude measures how far north or south a point is from the Equator, which is an imaginary line around Earth's middle. Longitude measures how far east or west a point is from the Prime Meridian, a line running through Greenwich, England. Together, these coordinates provide a unique address for any location worldwide, similar to how a map grid system works. This system is essential for navigation, mapping, and geographic information systems, allowing precise identification of any place on Earth.
