Latitude and longitude are used to locate any point on Earth. Latitude runs east-west and is the distance from the equator, ranging from 0 degrees at the equator to 90 degrees at the North and South Poles. Longitude runs north-south and is the distance from the Prime Meridian in Greenwich, England, ranging from 0 degrees to 180 degrees east and west. Together, a point's latitude and longitude precisely indicate its position on the globe.
