Really!
I'm thinking of things like this
"http://www.fell-walker.co.uk/page67.htm"
It might possibly have based it on existing material that would
be copyright but its my own sketch.

Well, if it has two sources, it wont be the same as either.

I think it will either be breach of copyright or not,
irrespective of how much you do.

I might have the wrong end of the stick here, you are using
software to produce "their" map, so its their copyright, but they
say:-
"You are licensed to do whatever you like with the map, as long
as you do not charge for it (normal open source licensing rules
apply), and give due credit."
so I would have thought as long as you credit them and say "part
of this mapping was based on blah blah, they and I are not
responsible for any errors". Probably worth asking them if they
object to changes, although they appear to have already said its
OK to do what you like?

I don't think the OS will object if you're adding *info* you
obtained from their maps, as opposed to copying their map

Er, not sure what you're saying there.
