Having received nothing but positive feedback I'll put figuring out how to do this on my to-do list if there are no objections. I may come back for more consultation if I feel it necessary after looking at the technical steps. I won't conduct this edit before Friday at the absolute soonest.
We probably need to have a bigger look at cleaning up California landuse imports, there is some weird and wrong stuff there, but that's a wider discussion that doesn't need to stop us from removing the clearly wrong stuff. > From: Paul Norman [mailto:[email protected]] > Sent: Friday, June 14, 2013 3:29 PM > To: OpenStreetMap US Talk > Subject: [Talk-us] Cleaning up California FMMP "residential" > > I've been doing some California landuse and have come across a lot of > landuse=residential imported from FMMP which is clearly wrong.
