  2. Universal polar stereographic coordinate system - Wikipedia

    en.wikipedia.org/wiki/Universal_Polar...

    The universal polar stereographic (UPS) coordinate system is used in conjunction with the universal transverse Mercator (UTM) coordinate system to locate positions on the surface of the Earth. Like the UTM coordinate system, the UPS coordinate system uses a metric-based cartesian grid laid out on a conformally projected surface.

  4. Stereographic map projection - Wikipedia

    en.wikipedia.org/wiki/Stereographic_map_projection

    The stereographic projection was likely known in its polar aspect to the ancient Egyptians, though its invention is often credited to Hipparchus, who was the first Greek to use it. [ citation needed ] Its oblique aspect was used by Greek Mathematician Theon of Alexandria in the fourth century, and its equatorial aspect was used by Arab ...

  5. Stereographic projection - Wikipedia

    en.wikipedia.org/wiki/Stereographic_projection

    A two-dimensional coordinate system on the stereographic plane is an alternative setting for spherical analytic geometry instead of spherical polar coordinates or three-dimensional cartesian coordinates. This is the spherical analog of the Poincaré disk model of the hyperbolic plane.

  8. 3-sphere - Wikipedia

    en.wikipedia.org/wiki/3-sphere

    The four Euclidean coordinates for S 3 are redundant since they are subject to the condition that x 0 2 + x 1 2 + x 2 2 + x 3 2 = 1. As a 3-dimensional manifold one should be able to parameterize S 3 by three coordinates, just as one can parameterize the 2-sphere using two coordinates (such as latitude and longitude).

  9. Military Grid Reference System - Wikipedia

    en.wikipedia.org/wiki/Military_Grid_Reference_System

    The Military Grid Reference System (MGRS) [1] is the geocoordinate standard used by NATO militaries for locating points on Earth. The MGRS is derived from the Universal Transverse Mercator (UTM) grid system and the Universal Polar Stereographic (UPS) grid system, but uses a different labeling convention.
