I am not convinced by all this!
There are several issues here:
(1) The Ordnance Survey information: first published in this form in 1873, and
therefore out of copyright since 1924. I suspect this is what Humphrey
Southall is really trying to get at, in which case he has nothing to worry
about.
(2) Brian Harley's notes - in copyright until 31 Dec 2061.
(3) The IMAGE reproduced by D & C: if one abstracts, say, boundaries FROM the
image then copyright, if any, lies in the INFORMATION, *not* in the *image*:
if one reproduces the image then there might be an infringement of D & C
copyright - but does reproducer's copyright in a reproduced image run for more
than 25 years?!
