It's more important to be self-consistent than to follow another project's lead, even a well-respected one. Or to phrase it differently, sticking with your decision is more important than what your actual decision is. That said, I think that the "coastline is at mean high-water spring tide" principle is the most common (sometimes using "high-water mark" instead, which is close enough). > look at the EPA map http://gis.epa.ie/Envision / > http://wiki.openstreetmap.org/wiki/Corine_Land_Cover and see what is land, > transitional waterbody, coastline. AFAIU Corine doesn't have a notion of "coastline" the way OS does. It just deals with landcover, and categorizes those as salt marsh, which is an easy decision in OSM too. The OSi map on that website shows the north part of the wetland as land and the south part as water, which is really bogus and a nice example of the official government-funded maps not always being the best :p _______________________________________________ Talk-ie mailing list [email protected] https://lists.openstreetmap.org/listinfo/talk-ie
