  These two sentences frame the problem exactly: translating a distance and
direction from a known georeferenced point to another georeferenced point.
Then taking the distance/bearing to the next point and georeferencing that.

  Sure, once all the nodes are georeferenced the rest is easy. But, it's the
georeferencing step to which I referred. I infer from your answer that no
one on the list has looked into this. Guess it's research time for ol' Rich
in the Land of Geodesy.
