I don't but it should be relatively easy to compute using the following algorith: - At each node on the coastline, produce a circle of 12 nmi. - Remove all circle points that are inside some other circle. - simplify Since the coastline ends somewhere, there may be some edge effects that need fixing afterwards. -- Morten _______________________________________________ talk mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk
