Hello,
I see that you have tried to undo much of this edit since making it. I have attempted to undo other parts that looked like they were probably mistakes. Sorry if I have undone anything that was actually intentional.

Connectivity looks OK to me.

Actually adding a building passage, forgot to update the changeset comment.

Hello. Have you visited this? The satellite imagery looks like it might be `man_made=quay`.

man_made=quay

Please try to provide a changeset comment that's actually informative. Especially when the bounding box covers over half a dozen countries and territories.

The issues are well clarified in OSM guidelines where it says "Do not use data from copyrighted maps or any other proprietary data!" in bold text on the copyright page: osm.wiki/Copyright

This will probably confuse many people.

I think that probably still counts as copying as some of the well known copyright "traps" on maps include fictitious settlements and place names.

1993 is not old enough for the copyright to have expired. This would not be an acceptable source unless you have permission from the authors.

OSM?
