I think it is.
I even think you can release it under the GNU public License,
*adding* to a Copyright for Barry Rowlingson (and yourself if you want).

sounds great.

??  they *did* approve the distribution of the uk() map data,
   but you haven't included it?  [I must have misunderstood ..].

yes!  and as said above, I think there's no real license problem left
from what I read above [but then I may be not enough strict ..].
