Thinking just that, I removed the place=island tag from every piece of coastline and made a relation out of all the pieces of coastline: http://www.openstreetmap.org/browse/relation/536255 ... but the problem persists.

Not using some dirty hack. :-) The problem is everything except the coastlines update within minutes, so now people assume everything does and when it doesn't they complain on mailing lists or diary entries or Realistically it's no more of a hack than generating shape files to get around rendering problems with broken coast lines. ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

I can't see any obvious reason why the islands would be missing. The coastline generating utility really only cares about things tagged with natural=coastline so any other tags like place=island should have no effect on it.

[OSM-talk] Project of the Week 2010Mar28 - Swimming in data
Many of the coastlines in OSM came from an import of the PGS coastline data. It was a fantastic benefit to be able to add this coastline data to OSM, and we're better off having had it. And there are many places that have aerial imagery that is now good enough to improve on PGS coastlines. So that is the project of the week for 28 March, 2010, check your favorite bit of coastline and improve what you can with overhead imagery. Those without a favorite bit of unimproved coastline might take a look at the crenelated coasts of North America for examples of what can be improved. This http://www.openstreetmap.org/edit?lat=41.044lon=-72.1591zoom=14 is a portion of Long Island with aged PGS coastline that fails to meet our current standards for Good Coastiness. Sure, it will be fixed up by the time the second reader gets to it, but have a look at that area in the original bulk import form, http://www.openstreetmap.org/browse/changeset/693806 . Okay, perhaps we can make our current imports a little friendlier to view. And now a sea change Let's improve the Project of the Week while we're improving the map. Let's increase participation. If you are participating in potw, consider posting some of your before and after shots of the areas you are mapping. Reply with your comments and links to your good work. Consider adding potw to your changesets. It's nice to know if you find a project of the week interesting. Propose a Project of the Week. Write it up and add it to the Proposals page, or email me directly. http://wiki.openstreetmap.org/wiki/Project_of_the_week/Proposals Make general or specific suggestions regarding potw on the discussion page. http://wiki.openstreetmap.org/wiki/Talk:Project_of_the_week/Proposals Share your project! Detailed, written potw proposals are very warmly welcomed. Tell us what you are doing, show us how it is making a difference, and let us know how we can help you with your project locally, or by replicating it in our neighborhood. Give some example tags and guidelines if you can. The massively successful Image of the Week project has been running since 2006, and is now a flipbook history of What Was New In OSM. Plus a couple of entertaining April Fool images. Part of the strength of the IotW is the indefatigable leadership of User:Ojw who has kept it running for five years. Much of the strength of IotW comes from the community interest. Folks do something interesting, make an image, and share it with IotW. Let's see if we can make potw at least half as interesting and informative as IotW. Join in, won't you? If you haven't seen IotW (What? Is that possible?!?!) You must see it now. Prepare to spend an hour learning the visual history of OSM. http://wiki.openstreetmap.org/wiki/Featured_images ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
