The 27th? Damn.  I thought it was going to go read-only on the 1st...  At least that's what I've been telling people who I've been contacting to see if they will accept the new CT (which is still being somewhat successful geting at least 2-3 people a day to accept). Ugh. - James

> Tools to use:
> 
> JOSM license change plugin. Select everything in an area and hit the
> "License Check" button. Start deleting red things and replacing them
> from clean sources:

> 
> Potlatch2 I think now has the license change layer enabled by default.
> If not, go into the options and make sure "Show license status" is
> checked. Again... remove anything with a red halo and replace.

> Badmap. Dirty interstates are clearly visible:
> http://cleanmap.poole.ch/?zoom=5&lat=41.12823&lon=-99.48465&layers=00B0
> 
> OSM Inspector. Good for drilling down and finding individual objects to remap:
> http://tools.geofabrik.de/osmi/?view=wtfe&lon=-100.24219&lat=40.17384&zoom=4
> 
> TIGER 2011 road name tiles. Used as a background imagery layer while
> editing. Good to pull street names while remapping residential areas.
> Just be sure to expand the abbreviations while you're at it.

> come back later and clean up the route relations after the license
> change.
