There's no river routing in the API. I guess there's not much call for aquatic SatNav. The routing database is created by companies working with SatNav devices.
For wide rivers, do store the data as polygons, not a pair of polylines. Code exists for determining if a click is inside a polygon [Google clickable polygons, and EPoly.Contains()]. Rather than drawing both banks for narrow rivers you might consider doing what Google do with roads. Record only the centre line, and snap the user clicks to that line. That saves half the data entry for narrow rivers. Or draw the centre line, then fatten it into a thin polygon and treat it like a wide river. -- Mike Williams http://econym.org.uk/gmap --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google Maps API" group.
