Longitude: The angle between the prime meridian and any point. Latitude: The angle between the equator and any point, measured from the center of the Earth. These spherical coordinates (latitude and longitude) indicate locations on a 3-dimensional representation of the Earth. In other words, going from the North Pole to the South Pole is 180 degrees. As we move North-South, we change through 180 degrees. In other words, the Earth is 360 degrees around. As we move East-West, we change through 360 degrees. The lines running North to South are called lines of longitude, while the lines running East to West are called lines of latitude. When we describe the Earth in spherical coordinates it is called Geographic, or Un-projected.
