Eric,

Thanks for the info.

I might be mistaken, but I recall looking at the public "crowd
sourcing" pilot.  I noticed that a lot of edits submitted by the
public were sourced from copyright or license restricted sources.
There were comments from contributors like "per Google" or "per
yellowpages.com."  I wonder what the USGS's stance on these sources
is?

Mike
