calculate gps points?

[ringmyr]

hello
working on a gps program / treasure hunt app and I have set out some GPS points.
now the question.
how do I calculate the closest point, so it comes up on the phone and it counts down to that point, when you start moving

If there aren't too many points then you can calculate the distance from the current point to each other point and show the closest one.
