Hi Karen,

It's definitely going to be possible to use other sources of data in 
OpenStreetMap real-soon-now.  The intention is that users will be able 
to trace maps from old (out-of-copyright) maps, and from satellite and 
aerial photography (so long as derivatives are permitted from the source 

Exactly how this would work is still an open question - as Saul has 
mentioned, I've been working on a rewrite of the current OSM applet, and 
I hope to have image tracing working by next week, but my main aim was 
to reduce the size of the applet and make the maps look a bit nicer.

If you can get hold of good aerial photographs of Paris, which can be 
accurately registered on a map, and are licensed in a way that allows 
derivative works to be distributed under an open license, then we should 
be able to help.  Until then, it's GPS only I'm afraid.

Hope that helps,
