There will always be a problem that the flood blocker removes too much of the sea area. Regarding you example: I think the road must be tagged with bridge=yes. Have a look on the wikipedia photos and decide yourself: http://en.wikipedia.org/wiki/File:Deltawerke-Oosterschelde-Sturmflutwehr_Oos... http://en.wikipedia.org/wiki/File:Pont_de_Zeelande.JPG But in general the flood blocking logic must be more gentle to some mapping oddities. I think Felix has made a good proposal. Any other ideas?
How about highways on dikes or dams? http://www.openstreetmap.org/?lat=51.66033&lon=3.72579&zoom=16&layers=M _______________________________________________ mkgmap-dev mailing list mkgmap-dev@lists.mkgmap.org.uk http://www.mkgmap.org.uk/mailman/listinfo/mkgmap-dev
