Well I disagree there, so I would like to hear other peoples thoughts on this. I disagree because, * The wiki lists natural=bay as appliciable to ways * a Bay as defined by the wiki "is an area of water", not a point in the middle of a body of water. * mapped as way allows renderers to for instance render names for large bays at low zooms, and not render names for small bays untill very high zooms. * mapped as a way allows for someone to use the database to ask "Am I in ... Bay?" * yes, some or most of the time it is hard to find the exact sea side boundary of the bay, I don't thing that should be a reason for not using a roughly placed a way in lure of some "official" extent. > Given the problem of rendering polygons as natural=bay and the > rareness of this I think that Richard Weait's tagging should be used > and the tagging of polygons as natural=bay should be deprecated. > > If the body of water requires a polygon and tagging, then it should be > tagged natural=water, which does not have these problems. Don't map for the renderer http://wiki.openstreetmap.org/wiki/Good_practice#Don.27t_map_for_the_renderer. That said, if other people agree that a large area which is named "... Bay", should have the tag natural=bay rather than natural=water, it shouldn't be too hard for renders to start rendering bays the same as natural=water. _______________________________________________ newbies mailing list [email protected] http://lists.openstreetmap.org/listinfo/newbies
