Oct 5, 2018 · Geographic coordinate system. A geographic coordinate system (GCS) defines locations on the earth using a three-dimensional spherical surface [1], it is a reference system that uses latitude and longitude to identify locations on a spheroid or sphere. A datum, prime meridian, and angular unit are parts of a GCS [2] .
Coordinate systems in astronomy can specify an object's position in three-dimensional space or plot merely its direction on a celestial sphere, if the object's distance is unknown or trivial. Spherical coordinates, projected on the celestial sphere, are analogous to the geographic coordinate system used on the surface of Earth.

Mar 25, 2024 · latitude and longitude, in cartography, a coordinate system used to determine and describe the position of any place on Earth ’s surface. Latitude is a measurement of a location north or south of the Equator. In contrast, longitude is a measurement of location east or west of the prime meridian at Greenwich (an imaginary north-south line that ...

The Swiss coordinate system (or Swiss grid) is a geographic coordinate system used in Switzerland and Liechtenstein for maps and surveying by the Swiss Federal Office of Topography ( Swisstopo ). A first coordinate system was introduced in 1903 under the name LV03 ( Landesvermessung 1903, German for “land survey 1903”), based on the ...
t. e. A projected coordinate system – also called a projected coordinate reference system, planar coordinate system, or grid reference system – is a type of spatial reference system that represents locations on Earth using Cartesian coordinates ( x, y) on a planar surface created by a particular map projection.
