A geographic coordinate system is a coordinate system used to indicate a point on Earth based on latitude and longitude. Latitude is a horizontal line that measures the angle between a point and the equator. The point north of the equator is called north latitude while the point south of the equator is called south latitude. Longitude is a vertical that measures the angle between a point and zero on Earth, namely Greenwich in London, United Kingdom, which is the internationally agreed point of 0° or 360° longitude. The point west of 0° longitude is called West Longitude, while the point east of 0° is called East Longitude. A point on Earth can be described by combining the two measurements. For example 7° South Latitude 110° East Longitude.
