With apologies (maybe ;) ) for being dogmatic, but...

Any photographic imagery (whether aerial, or scans of ooc material, or  
whatever) that restricts derivative works, such as through an -nc  
clause, is imposing additional contractual crap over and above  
copyright law. I've blogged previously (http://www.systemed.net/blog/?p=100 
) about case law relating to this in both the UK and US.

People like Google are, of course, free to impose their own  
contractual restrictions on deriving, but such imagery doesn't belong  
in any open map.
