Need some advice | | BTW, if you are not familiar with the antipodal problem - try the
following (WGS84)
Start at N0, E0 and proceed 19987.13950km with an initial course of
45 degrees (direct problem). You should end up at N0, E179 degrees
34.406 min.
Now try the inverse problem between these points. Vicenty won't
converge. Sodano, I believe, just gets the wrong answer. Bowring gets
it right.
