Road sign marking the equator near Nanyuki, Kenya. The latitude of the Earth's equator is, by definition, 0° (zero degrees) of arc.The equator is one of the five notable circles of latitude on Earth; the other four are the two polar circles (the Arctic Circle and the Antarctic Circle) and the two tropical circles (the Tropic of Cancer and the Tropic of Capricorn).
The Ciudad Mitad del Mundo (Middle of the World City) is a tract of land owned by the prefecture of the province of Pichincha, Ecuador. It is located at San Antonio parish of the canton of Quito, 26 km (16 mi) north of the center of Quito. The grounds contain the Monument to the Equator, which highlights the exact location of the Equator (from ...
A right-handed convention, specifying a y axis 90° to the east in the fundamental plane and a z axis along Earth 's north polar axis. This frame is in every way equivalent to the ξ, η, ζ frame, above, except that the origin is removed to the centre of the Sun. It is commonly used in planetary orbit calculation.
The 180th meridian on a map of Earth. The International Date Line zigzags around the 180th Meridian. The 180th meridian or antimeridian[1] is the meridian 180° both east and west of the prime meridian in a geographical coordinate system. The longitude at this line can be given as either east or west. On Earth, the prime and 180th meridians ...
The line down the middle of this 1911 map is the prime meridian, shown passing through Greenwich. Saxavord and Balta at the top of the map are in the Shetland Islands, the most northerly parts of Scotland and the United Kingdom. Shetland lies 1° W of the prime meridian.
t. e. A geographic coordinate system (GCS) is a spherical or geodetic coordinate system for measuring and communicating positions directly on Earth as latitude and longitude. [1] It is the simplest, oldest and most widely used of the various spatial reference systems that are in use, and forms the basis for most others.
Geodetic coordinates are a type of curvilinear orthogonal coordinate system used in geodesy based on a reference ellipsoid. They include geodetic latitude (north/south) ϕ, longitude (east/west) λ, and ellipsoidal height h (also known as geodetic height[1]). The triad is also known as Earth ellipsoidal coordinates[2] (not to be confused with ...
Map all coordinates using OpenStreetMap. The 32nd parallel south is a circle of latitude that is 32 degrees south of the Earth's equatorial plane. It crosses the Atlantic Ocean, Africa, the Indian Ocean, Australasia, the Pacific Ocean and South America. At this latitude the sun is visible for 14 hours, 19 minutes during the December solstice ...
