i've got a situation come up, that i'm not sure how to map: http://openstreetmap.org/?lat=-36.9241&lon=174.77611&zoom=17&layers=0B0FF
this shows a park which is near the coast. it includes an area of water linked, by a man-made tunnel, to the ocean, wholly contained with in the park. previously, it was completely open to the sea - the motorway to the south since built on a causeway has cut it off, apart from the tunnel. therefore, the area of water is tidal, and hence is demarcated from land by the coastline how could this be mapped/tagged? initially, i tagged the coastline as layer=1 to make it show up on the renderers above the park (by default, park renders above coastline AFAICS). any ideas? should the lagoon be tagged as coastline as i have done, or is that stretching a point too far? i don't think the park stops at the water's edge, so cutting a hole in it is not suitable this also brings up the question of what happens when a park (such as the great barrier reef) extends over an ocean/islands: does it obscure what is underneath? is there a way round this? _______________________________________________ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/cgi-bin/mailman/listinfo/talk
