  2. South Pole - Wikipedia

    en.wikipedia.org/wiki/South_Pole

    The South Pole is by definition the southernmost point on the Earth, lying antipodally to the North Pole. It defines geodetic latitude 90° South, as well as the direction of true south. At the South Pole all directions point North; all lines of longitude converge there, so its longitude can be defined as any degree value. No time zone has been ...

  3. Magnetic declination - Wikipedia

    en.wikipedia.org/wiki/Magnetic_declination

    True north is the direction along a meridian towards the geographic North Pole. Somewhat more formally, Bowditch defines variation as "the angle between the magnetic and geographic meridians at any place, expressed in degrees and minutes east or west to indicate the direction of magnetic north from true north.

  4. South magnetic pole - Wikipedia

    en.wikipedia.org/wiki/South_magnetic_pole

    The south magnetic pole, also known as the magnetic south pole, is the point on Earth's Southern Hemisphere where the geomagnetic field lines are directed perpendicular to the nominal surface. The Geomagnetic South Pole, a related point, is the south pole of an ideal dipole model of the Earth's magnetic field that most closely fits the Earth's ...

  5. Earth's magnetic field - Wikipedia

    en.wikipedia.org/wiki/Earth's_magnetic_field

    The North geomagnetic pole (Ellesmere Island, Nunavut, Canada) actually represents the South pole of Earth's magnetic field, and conversely the South geomagnetic pole corresponds to the north pole of Earth's magnetic field (because opposite magnetic poles attract and the north end of a magnet, like a compass needle, points toward Earth's South ...

  6. Cardinal direction - Wikipedia

    en.wikipedia.org/wiki/Cardinal_direction

    The directions are named by adding "disha" to the names of each god or entity: e.g. Indradisha (direction of Indra) or Pitrdisha (direction of the forefathers i.e. south). The cardinal directions of the Hopi language and the Tewa dialect spoken by the Hopi-Tewa are related to the places of sunrise and sunset at the solstices, and correspond ...

  7. Universal polar stereographic coordinate system - Wikipedia

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

    Specifically, the projection used in the system is a secant version based on an elliptical model of the earth. The scale factor at each pole is adjusted to 0.994 so that the latitude of true scale is 81.11451786859362545° (about 81° 06' 52.3") North and South.

  8. Azimuthal equidistant projection - Wikipedia

    en.wikipedia.org/wiki/Azimuthal_equidistant...

    An azimuthal equidistant projection about the North Pole extending all the way to the South Pole An azimuthal equidistant projection about the South Pole extending all the way to the North Pole Emblem of the United Nations containing a polar azimuthal equidistant projection. The azimuthal equidistant projection is an azimuthal map projection.

  9. Horizontal coordinate system - Wikipedia

    en.wikipedia.org/wiki/Horizontal_coordinate_system

    All directions are south when viewed from the North Pole, and all directions are north when viewed from the South Pole, so the azimuth is undefined in both locations. When viewed from either pole, a star (or any object with fixed equatorial coordinates ) has constant altitude and thus never rises or sets .
