This is something that interests me.

Let's say we have a non-OS map, like the Johnson one, from 1947.  
Clearly the map is still in copyright because it's (at best) 70 years  
since the end of 1947, (at worst) 70 years since the death of the  
author.

But many such maps were made using OS data, which is out of copyright  
after just 50 years.

Is it legal to trace tracks from such a map? After all, even if the  
map isn't out of copyright, the underlying data is.
