Vincenty http://en.wikipedia.org/wiki/Vincenty's_formulae is the current benchmark for distance between two points. If you think you've done better, you've got two real options:
(1) A GPS/Navigation Journal, or
(2) Surveying journal
Forget computer science - not really interested in this problem.
As far as conferences are concerned, it's worth trying to get into one of the following:
* IEEE PLANS http://www.plansconference.org/
* ION PLANS http://www.ion.org/meetings/
If you think it's still good for a journal, look for who has cited Vincenty's paper in Google Scholar - it will give you a good indication as to what journals to chase.
