Compute true course and distance between points.
I don't know if I have something which may solve part of your problems. I travelled a lot, before retiring, and always kept a note of cities visited, and stopovers on the way. I decided, one day to feed all of my data into a TRAVEL stack, to see how far I had really travelled (finally, more than 2 million klicks). I picked uf a file on the internet with position co-ordinates of 10,000 cities in the world, and than converted these co-ordinates to Lat/Long in radians. Then with a Haversine formula, I can calculate the distance between any two cities in the world (in km.), with up to 6 stopovers. example : Paris-Lisbon-Rio-London-Paris. You can, of course, feed in co-ordinates of any point on the globe, of any small town not in the list of 10,000 ! If my calculations are of use, just shout !.
