![]() The points of latitude and longitude are called coordinates, and can be used together to locate any point on Earth.WGS 84 coordinate reference system is the latest revision of the World Geodetic System, which is used in mapping and navigation, including GPS The imaginary lines of latitude and longitude intersect each other, forming a grid that covers Earth. Similar to latitude, the corresponding measurement of distance around the Earth is called longitude. Using seconds of latitude, global positioning system (GPS) devices can pinpoint schools, houses, even rooms in either of these towns. The latitude for Cape Town, South Africa, would be 33° 56' S, because the city is 33 degrees, 56 minutes south of the Equator. For example, the latitude for Cairo, Egypt, in degrees and minutes would be written as 29° 52' N, because the city is 29 degrees, 52 minutes north of the Equator. One minute of latitude covers about 1.8 kilometers (1.1 miles) and one second of latitude covers about 32 meters (105 feet). To be even more precise, those minutes are divided into 60 seconds. Degrees of latitude are divided into 60 minutes. At the North and South Poles, arc degrees are simply points. Because of Earth's curvature, the farther the circles are from the Equator, the smaller they are. One degree of latitude, called an arc degree, covers about 111 kilometers (69 miles). The tropics are important geographic locations that mark the northernmost and southernmost latitudes where the sun can be seen directly overhead during a solstice. Its twin, the Tropic of Capricorn, is 23° 26' 21'' S. The Tropic of Cancer, for instance, is 23 degrees 26 minutes 21 seconds N-23° 26' 21'' N. Like the poles, some circles of latitude are named. The latitude of the North Pole is 90 degrees N, and the latitude of the South Pole is 90 degrees S. Each parallel measures one degree north or south of the Equator, with 90 degrees north of the Equator and 90 degrees south of the Equator. ![]() The Equator is the line of 0 degrees latitude. A circle of latitude is an imaginary ring linking all points sharing a parallel. ![]() ![]() It is measured with 180 imaginary lines that form circles around Earth east-west, parallel to the Equator. Latitude is the measurement of distance north or south of the Equator. ![]()
