2. Great-circle navigation - Wikipedia

   en.wikipedia.org/wiki/Great-circle_navigation

   Great-circle navigation or orthodromic navigation (related to orthodromic course; from Ancient Greek ορθός (orthós) 'right angle' and δρόμος (drómos) 'path') is the practice of navigating a vessel (a ship or aircraft) along a great circle. Such routes yield the shortest distance between two points on the globe. [1]

3. Comparison of free off-line satellite navigation software

   en.wikipedia.org/wiki/Comparison_of_free_off...

   Some of the free software mentioned here does not have detailed maps (or maps at all) or the ability to follow streets or type in street names (no geocoding). However, in many cases, it is also that which makes the program free (and sometimes open source [ 1 ] ), avoid the need of an Internet connection, [ 2 ] [ 3 ] [ 4 ] and make it very ...

4. Great-circle distance - Wikipedia

   en.wikipedia.org/wiki/Great-circle_distance

   A diagram illustrating great-circle distance (drawn in red) between two points on a sphere, P and Q. Two antipodal points, u and v are also shown. The great-circle distance, orthodromic distance, or spherical distance is the distance between two points on a sphere, measured along the great-circle arc between them. This arc is the shortest path ...

   The first public release of the beta Here app (across all Android platforms) was on 21 October 2014, as an APK download from the HERE.com Web site. [17] The app became available in the Google Play store on 10 December 2014. [18] On 12 February 2015, a stable version of HERE Maps was released on the Google Play store. [19]

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.

8. Vincenty's formulae - Wikipedia

   en.wikipedia.org/wiki/Vincenty's_formulae

   They are based on the assumption that the figure of the Earth is an oblate spheroid, and hence are more accurate than methods that assume a spherical Earth, such as great-circle distance. The first (direct) method computes the location of a point that is a given distance and azimuth (direction) from another point.

9. Great circle - Wikipedia

   en.wikipedia.org/wiki/Great_circle

   The disk bounded by a great circle is called a great disk: it is the intersection of a ball and a plane passing through its center. In higher dimensions, the great circles on the n-sphere are the intersection of the n-sphere with 2-planes that pass through the origin in the Euclidean space R n + 1. Half of a great circle may be called a great ...
