That's the whole basis of how Walking Papers works (no measuring tool 
involved) - you locate new items by referring to the existing data.

And it is also Ordnance Survey's oft-stated contention that this is 
indeed derivation - if you geolocate a photo by reference to map 
features, that is derived.
