I would add the code from getMapPoints to getMapPath, as both functions do a network call and that is wasteful (probably the browser would serve the second call from cache, but still). Also the two function has some common code. You can rename the function to something more generic.

Ok, I've made it a single getMapCoordinates[][] instead, which returns the array of arrays coordinates = [path,wpoints] - so there's only one network call to the GPX file, but 2 calls to getElementsByTagName in getMapCoordinates(). I hope that's good enough :)

That is perfect, thank you.

Can you clean up this part a bit? removing unnecessary comments, etc. Otherwise this PR looks good.

You can reuse the interface above. Maybe refactor it to something like MapCoordinates.
