Latitude and longitude are a system of geographic coordinates that are used to locate a point on the Earth’s surface. Latitude is the measurement of the angle between a point and the Equator, ranging from 0 degrees at the Equator to 90 degrees at the North and South Poles. Longitude is the measurement of the angle between a point and the Prime Meridian, which is located at the Royal Observatory in Greenwich, England, ranging from 0 degrees to 180 degrees east or west.
Latitude and longitude are essential for navigation and mapping. They allow us to determine the location of a place on Earth, and to calculate distances and directions between different places. Latitude and longitude are also used in a variety of other applications, such as weather forecasting, geology, and surveying.
