  2. Geographical distance - Wikipedia

    en.wikipedia.org/wiki/Geographical_distance

    View from the Swabian Jura to the Alps. Geographical distance or geodetic distance is the distance measured along the surface of the Earth, or the shortest arch length.. The formulae in this article calculate distances between points which are defined by geographical coordinates in terms of latitude and longitude.

  3. Geographic coordinate conversion - Wikipedia

    en.wikipedia.org/wiki/Geographic_coordinate...

    Informally, specifying a geographic location usually means giving the location's latitude and longitude.The numerical values for latitude and longitude can occur in a number of different units or formats: [2]

  4. Decimal degrees - Wikipedia

    en.wikipedia.org/wiki/Decimal_degrees

    Decimal degrees (DD) is a notation for expressing latitude and longitude geographic coordinates as decimal fractions of a degree.DD are used in many geographic information systems (GIS), web mapping applications such as OpenStreetMap, and GPS devices.

  5. 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.

  6. Haversine formula - Wikipedia

    en.wikipedia.org/wiki/Haversine_formula

    The haversine formula determines the great-circle distance between two points on a sphere given their longitudes and latitudes. Important in navigation , it is a special case of a more general formula in spherical trigonometry , the law of haversines , that relates the sides and angles of spherical triangles.

  7. Longitude - Wikipedia

    en.wikipedia.org/wiki/Longitude

    The length of 1 minute of longitude along the equator is 1 geographical mile or 1.855 km or 1.153 miles, while the length of 1 second of it is 0.016 geographical mile or 30.916 m or 101.43 feet. See also

  8. Latitude - Wikipedia

    en.wikipedia.org/wiki/Latitude

    The conformal and geocentric latitudes are nearly indistinguishable, a fact that was exploited in the days of hand calculators to expedite the construction of map projections. [ 9 ] : 108 To first order in the flattening f , the auxiliary latitudes can be expressed as ζ = ϕ − Cf sin 2 ϕ where the constant C takes on the values [ 1 ⁄ 2 ...
