  2. History of longitude - Wikipedia

    en.wikipedia.org/wiki/History_of_longitude

    Longitude calculations can be simplified using a clock is set to the local time of a starting point whose longitude is known, transporting it to a new location, and using it for astronomical observations. The longitude of the new location can be determined by comparing the difference of local mean time and the time of the transported clock.

  3. Earth-centered, Earth-fixed coordinate system - Wikipedia

    The reverse conversion is harder: given X-Y-Z can immediately get longitude, but no closed formula for latitude and height exists. See "Geodetic system." Using Bowring's formula in 1976 Survey Review the first iteration gives latitude correct within 10-11 degree as long as the point is within 10,000 meters above or 5,000 meters below the ellipsoid.

    Grid Zone Designation (GZD); for a world-wide unique address. This consists of up to 2 digits (6-degree longitude UTM zone) for West to East, followed by a letter (8-degree latitude band) from South to North; in this example, "18S". [10] [11] 100,000-meter (100 km) Square Identification; for regional areas.

  5. Longitude - Wikipedia

    en.wikipedia.org/wiki/Longitude

    The lines from pole to pole are lines of constant longitude, or meridians. The circles parallel to the Equator are circles of constant latitude, or parallels. The graticule shows the latitude and longitude of points on the surface. In this example, meridians are spaced at 6° intervals and parallels at 4° intervals.

  6. Geodetic coordinates - Wikipedia

    en.wikipedia.org/wiki/Geodetic_coordinates

    Geodetic latitude and geocentric latitude have different definitions. Geodetic latitude is defined as the angle between the equatorial plane and the surface normal at a point on the ellipsoid, whereas geocentric latitude is defined as the angle between the equatorial plane and a radial line connecting the centre of the ellipsoid to a point on the surface (see figure).

  7. Google Latitude - Wikipedia

    Google Latitude was a location-aware feature of Google Maps, developed by Google as a successor to its earlier SMS-based service Dodgeball.Latitude allowed a mobile phone user to allow certain people to view their current location.

  9. Geographical zone - Wikipedia

    en.wikipedia.org/wiki/Geographical_zone

    The five main latitude regions of Earth's surface comprise geographical zones, [1] divided by the major circles of latitude. The differences between them relate to climate. They are as follows: The North Frigid Zone, between the North Pole at 90° N and the Arctic Circle at 66°33′50.3″ N, covers 4.12% of Earth's surface.
