[OSM-talk] USGS map areas with street names

Tue Jan 26 01:38:10 GMT 2010

OK, I went back and found the message referenced on the wiki:
http://lists.openstreetmap.org/pipermail/talk/2010-January/047477.html

J-G forwarded a message that included a link to the USGS maps.  The message
was in response to someone looking for an updated street index, and it spun
off from there.  If we need further confirmation, user osmapb1--oh, that's
Adrian--has gone and checked 9 areas and found no differences.  So, yes, I'd
recommend removing it.  Plenty of other things to work on!  (if noone else
does it in the next hour or two, I'll do when I have another chance).
