Re: [Talk-us] County Line Corrections
I know of some weird cases of borders and rivers, particularly along the Mississippi, where it has changed course. There's a case near Wilson, Arkansas where the river has changed course, and a few square miles of land on the west side of the river belongs to Tennessee. However, for obvious practical reasons, the post office that services that area is based in Arkansas - so the same zip code crosses state lines. -Alan From: Adam Schreiber To: Minh Nguyen Cc: OpenStreetMap U.S. Sent: Wednesday, January 28, 2009 1:38:19 PM Subject: Re: [Talk-us] County Line Corrections On Wed, Jan 28, 2009 at 4:08 PM, Minh Nguyen wrote: > Kentucky's border along the Ohio River is one example: the border is > defined to be the low water mark of the Ohio-Indiana-Illinois bank as of > the 18th century [1], so it's not the centerline and not quite the > northern riverbank.

Re: [Talk-us] County Line Corrections
Kentucky's border along the Ohio River is one example: the border is defined to be the low water mark of the Ohio-Indiana-Illinois bank as of the 18th century [1], so it's not the centerline and not quite the northern riverbank. Along Ohio's section of the river, all the islands belong to Kentucky or West Virginia.

Re: [Talk-us] County Line Corrections
I think there may be cases where one shore or the other is the boundary, not the centerline. Presumably, islands in a river are in one county or the other?
