Hi Guys, I've written a kind of navigation system for pedestrians. The only thing is, that I need a criterion to finish the navigation.

My values are gives as lat/long pairs.

What would you assume would be a good value to say, both positions are equal/near enough to tell the user that he has reached the goal?

Please keep also in mind, that it's idfficult to say "directly equal", because GPS modules may have variances...
