The great circle (orthodrome) is behind the shortest distance between two points on the surface of our planet.In the common display of the world, the great circle runs over the map as a sinus curve.This app calculates this curve on basis of two (user defined) points and displays it. So you can see the shortest distance between the points and the flying time. And in addition, it simulates the movement of a vehicle along the great circle path.So catch the app and find out the reason why a flight from Los Angeles to Frankfurt proceeds so far in the north.Hintsto avoid missinterpretation or missunderstanding:1. This app displays the whole great circle, defined by departure and destination point. A flight from e.g. Denver to Bejing has two parts: a shorter via the northern part of the pacific ocean and a longer via the southern hemispere, both are displayed.2. To get every point in the map (to mark 'from' and 'to'), just zoom in with two fingers.
