[OSM-talk] USGS map areas with street names

Tue Jan 26 00:00:08 GMT 2010

I wrote (guessed) part of what is on the wiki because there was just 
this list of PDF documents and no furthern info. I'm looking for 
confirmations/corrections from people who are actually involved in 
producing these maps. Discussion was to  complete OSM data from the USGS 
maps but the way it looks now it doesn't make a lot of senset to me. And 
no, I didn't find any name I could have completed when I had a closer 
look at three samples areas.

Should we simply remove the whole section from the wiki?
