I've been aiming to tag bays as areas rather than just a node in the centre. As a consequence my initial thought was to tag the area as natural=bay. Traditionally most renderers didn't render this as water. the OSM Mapnik style now does, but many others still don't. The problem was I couldn't tag as both natural=water to get the rendering and natural=bay to indicate the type of feature. I've since realised that tagging as natural=water, water=bay could be a solution to use, but as natural=bay already had widespread use with nodes, I wanted to keep consistency. As Markus_g mentioned you could try to edit Navits stylesheets so it renders natural=bay areas as water (some times as a multipolygon), although... I'm not opposed to your suggestion of keeping a kind of coastline tag, I'm just not sure the best way to implement it, please discuss it if you like. * Perhaps the coastline tag should be reserved for the ocean facing coast. If we want to tag anything say inside a bay or harbour maybe we could use a shoreline tag. * A problem with tagging the area of a bay is that while the shoreline is mostly well defined, the other edge is fuzzy. A possible solution is to use a multi polygon relation to tag just the non-shoreline segments of the bay outline as fuzzy=*. I suppose that using a multipolygon relation you can keep jest the shoreline segments together in another relation for say a larger harbour or river.... _______________________________________________ Talk-au mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk-au
