  2. 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).

  5. Latitude - Wikipedia

    en.wikipedia.org/wiki/Latitude

    The Equator has a latitude of 0°, the North Pole has a latitude of 90° North (written 90° N or +90°), and the South Pole has a latitude of 90° South (written 90° S or −90°). The latitude of an arbitrary point is the angle between the equatorial plane and the normal to the surface at that point: the normal to the surface of the sphere ...

  6. History of longitude - Wikipedia

    en.wikipedia.org/wiki/History_of_longitude

    The clock would be set to the local time of a starting point whose longitude was known, and the longitude of any other place could be determined by comparing its local time with the clock time: [54] there is a four-minute difference between locally observed noon and clock noon for each degree of longitude east or west of the initial meridian.

    en.wikipedia.org/wiki/29th_parallel_north

    The 29th parallel north is a circle of latitude that is 29 degrees north of the Earth's equatorial plane. It crosses Africa, Asia, the Pacific Ocean, North America, and the Atlantic Ocean. At this latitude the sun is visible for 14 hours, 0 minutes during the summer solstice and 10 hours, 18 minutes during the winter solstice. [1]
