Daily Hack #day108 - Great Circle Map

Great Circle Map is a tool developed by Markus Englund for visualizing flight routes and calculating the distance between airports. A great circle path (also known as a geodesic path) is the shortest possible route between two points on the surface of earth or any other sphere.

The map uses the Mercator projection by default. On this type of map, great circle paths tend to look curved even though they are in fact straight. As an alternative, the website also features a 3D globe view which doesn’t have that problem.

Why don't you try it out and have a bit of fun calculating the distances of your next jet setting adventure. Just follow this link.

Alternatively, see an example I prepared earlier accessing this link. The full url can be found on the code snippet below.
