Incorporating the effect of latitudal motion into travel planning

score:4

Accepted answer

For flat maps and large distances, no. As Wikipedia's article on map projections makes clear, although a map projection can be chosen to preserve distance, it can only do so between one point (or two) and the rest of the world. So I could have a London equidistant projection map that preserved distances from London to everywhere else (and possibly similarly for one other point, which I guess to be the antipode of London), but it would not preserve eg distance from New York to Moscow. It would also preserve neither shapes nor areas, so it would look odd to an eye used to Mercator, as most of ours are.

Get yourself a decent globe and a piece of string, or learn to perform great-circle calculations yourself.

I use Google Earth in these instances.
