I've been guilty of mistakenly joining state boundaries to the Ohio River's thalweg in the past, and by now I've had to correct those boundaries on several occasions. It's unfortunate that few mappers are aware of these complexities. The full situation is spelled out in a wiki page: http://wiki.openstreetmap.org/wiki/Ohio_River If any other natural features tend to attract misinformed edits, I suggest writing up a similar page so you can easily point mappers to it in changeset comments etc. Ironically, I was recently involved in a minor car collision onboard a ferry crossing this river. The police officer who responded had to call around to verify that he had jurisdiction. Perhaps if his department had distributed OSM-based maps, we could've been on our way a bit sooner. ;-) -- m...@nguyen.cincinnati.oh.us _______________________________________________ talk mailing list talk@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk
