huh, haven’t been here for a while, it seems. This place looks different :)
Now: I want to move between two points on a sphere, taking the Great Circle Route (shortest possible distance)
While I can think of a couple of ways to do this, I want to be able to just put coords for origin and destination and be done with it. And this has me stumped for a while now.
Allow me to suggest you a nice article with a live Google map, where you 'll be able to move two waypoints and see the Great Circle and Rhumb Line in action.
Please follow this link: Great circle or rhumb line
I hope I helped a little…
