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 between the two points on the surface of the sphere.
Great Circle Map displays the shortest route between airports and calculates the distance. It draws geodesic flight paths on top of Google maps, so you can create your own route map.
To find the shortest route on a sphere, you need to use the so-called great circles. A great circle is the largest possible circle that can be drawn on a sphere, and can be defined as any circle that divides the sphere into two equal halves and is centered on the sphere's center.
Great circle: shortest distance between two locations on Earth ... Appendix
5 maj 2015 · The shortest distance between two points is a straight line, but when a line on a globe is shown on a two-dimensional map, it looks like an arc. The solid line is the actual flight path, the red dashed line is the Great Circle route between Chicago and Dubai.
The shorter segment between two points on a great circle is the shortest path between the two points on the sphere, also known as an orthodrome or the great circle distance. You may calculate the great circle distance between two points on the Earth from the geographical coordinates.
Great circle route, the shortest course between two points on the surface of a sphere. It lies in a plane that intersects the sphere’s centre and was known by mathematicians before the time of Columbus. Until the 19th century ships generally sailed along rhumb lines, which made use of prevailing.
