If it's government maps with permission, you could argue the case. But I'm especially
afraid a lot of "not so official" routes would be entered that way. I once
found a kayak club had entered it's weekend trip in OSM.
Another argument against mapping based on other maps with permission is that
it's a lot harder to verify. If we only map based on the presence of physical
markers on the ground, other mappers who pass by might be able to spot mistakes
or omission. On the other hand, when something is mapped based of an online
PDF, I'm afraid it will not get double checked so quickly anymore.
If the path is visible on satellite imagery it does give faith that there is at
least a path there.
Where past experience with that source has been good then I'd go ahead and use
it. Really depends on how much faith you place in the information.
I would map public footpaths, if I found information about them where the
copyright permits.
A collection of footpaths that somebody has defined as a walk is another
matter, because
copyright issues are more likely to arise. If the copyright permitted it,
would you deem
any of these

suitable or unsuitable? Many of them appear on maps on noticeboards. I'd
expect many to
be signposted and waymarked, but am too unhealthy to look. Would they only
be mappable
if signposted/waymarked or would a map without copyright problems be enough?
For me personally: only when waymarked. But I don't know how other view this
point, I'm interested in hearing different opinions.
I too would only include waymarked. Others can be mapped as paths, but not
assigned as routes.
