  2. Altitude - Wikipedia

    en.wikipedia.org/wiki/Altitude

    Pressure altitude is the elevation above a standard datum air-pressure plane (typically, 1013.25 millibars or 29.92" Hg). Pressure altitude is used to indicate "flight level" which is the standard for altitude reporting in the U.S. in Class A airspace (above roughly 18,000 feet).

  4. Horizontal coordinate system - Wikipedia

    en.wikipedia.org/wiki/Horizontal_coordinate_system

    The horizontal coordinate system is a celestial coordinate system that uses the observer's local horizon as the fundamental plane to define two angles of a spherical coordinate system: altitude and azimuth. Therefore, the horizontal coordinate system is sometimes called the az/el system, [1] the alt/az system, or the alt-azimuth system, among

    The centre of the standard geographic model as viewed on a traditional world map is the point 0°, 0° (the coordinates of zero degrees latitude by zero degrees longitude), which is located in the Atlantic Ocean about 614 km (382 mi) south of Accra, Ghana, in the Gulf of Guinea.

  7. Elevation - Wikipedia

    en.wikipedia.org/wiki/Elevation

    In aviation, the term elevation or aerodrome elevation is defined by the ICAO as the highest point of the landing area. It is often measured in feet and can be found in approach charts of the aerodrome. It is not to be confused with terms such as the altitude or height.

    1913 saw the beginning of the International Map of the World initiative, which set out to map all of Earth's significant land areas at a scale of 1:1 million, on about one thousand sheets, each covering four degrees latitude by six or more degrees longitude. Excluding borders, each sheet was 44 cm high and (depending on latitude) up to 66 cm wide.

  9. South Pole - Wikipedia

    en.wikipedia.org/wiki/South_Pole

    The South Pole is at an altitude of 9,200 feet (2,800 m) but feels like 11,000 feet (3,400 m). [34] Centripetal force from the spin of the planet throws the atmosphere toward the equator. The South Pole is colder than the North Pole primarily because of the elevation difference and for being in the middle of a continent. [35]
