A couple of things come to mind: - you need to ensure that you're using radians for cos and sin to work correctly (you may be, the code snippet doesn't make it clear) - where does 111.2 come from? You may want to use the haversine formula on each line segment. It's given at http://www.movable-type.co.uk/scripts/latlong.html among other places.
