Hi Tom,

Thanks for your message. I have an aerial photo dating from the early 1990s,
made by the IGN (=OS in England). I'm not sure of the rights on derivative
material though; I used it several years ago as a basis for a derivative
artwork on CD-Rom (Paris Réseau/Network). They were going to charge a
fortune if I had used it outright; I assumed that it was Ok as long as you
couldn't really recognize the original.

I just changed my subscription from Digest to regular mode so I haven't yet
received the list version!

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,
