Greenwich meridian, an imaginary line, last established in 1851, used to indicate zero degrees longitude. It passes through Greenwich, London, and ends at the North and South poles. Because it indicated zero degrees longitude, it was also known as the pr
Geographic coordinates use positive and negative values to specify positions in relation to the Equator and the Prime Meridian. Locations north of the Equator and east of the Prime Meridian are marked with positive values. Conversely, positions that are south of the Equator or west of the Prime ...
The Airy-0 location was determined to be about 0.001掳 east of its predicted location using the currently defined International Astronomical Union (IAU) prime meridian location. Information on this new location and how it was derived will be provided to the NASA Mars Exploration Program Geodesy ...

Now slice it along the prime meridian, and then at right angles to both those cuts. In each hemisphere, number the spherical triangles from 0 to 3, with either “N” or “S” in the prefix. A triangle on a plane always has exactly 180°, but on the surface of a sphere and other...

Prime Meridian The Prime Meridian is the vertical line that marks the zero degree longitude measurement on the Earth Lines of Longitude Meridians A meridian (or line of longitude), is an imaginary arc on the Earth's surface from the North Pole to the South Pole that connects all locations ru...
primemeridian. Both latitude and longitude are measured in degrees (°), which may be broken down into smaller units called minutes (′) and seconds (″). (Or they may be expressed in decimal degrees; negative values of decimal degrees represent latitudes in the Southern Hemisphere and ...
LocationLongitude The location east or west in reference to the Prime Meridian, which is designated as zero (0) degrees longitude. The distance between lines of longitude are greater at the equator and smaller at the higher latitudes, intersecting at the earth's North and South Poles. Time zon...
LATITUDE: Angular distance measured north or south of the Equator from the center of the Earth. Such an angle circumscribed on the surface of the globe produces a parallel of latitude. LONGITUDE: Angular distance measured east or west of the Prime Meridian. Lines of longitude, called meridians,...
