I have lost track of the various initiatives to record aerial imagery
offsets but what you are asking for here is very similar - a note to
users of a certain aerial imagery source in a certain area, that
should ideally be popped up by the editor once the user gives the
impression of wanting to work in that area and has the imagery in
question on screen.

The simplest and most generic of these suggestions was to simply place
nodes with a specific tagging somewhere in the general area for the
editor to pick up and warn the user or auto-adjust aerial imagery. The
disadvantage obviously being that you'll miss the note if your edit
area doesn't include it, and that the database gets polluted with meta
objects (cf. discussion about "aerial imagery boundary" objects).

This could be improved to allow "remarks" that cover whole areas and
not only points (and btw. it needn't even be aerial imagery related -
once established, people might even put it to (mis?)use by drawing a
rectangle that pops up a message "mapping party here next weekend,
contact user at domain.com", and/or a different server could be used for
such meta data. A few months ago, Zverik launched a small project that
would allow you to chat with nearby other mappers active in the same
area - technologically it should be very easy to piggyback some
generic "area related messaging" function onto that because it already
implements the "editor sends area being edited to server, server
checks if others are in the same area and sends back a notify message"
bit.

A very interesting field that, if done well, can make mapping much
more collaborative (you may say "social" if you're so inclined) than
it is now!

I'm not sure why none of the aerial imagery offset correction ideas
has really established itself yet; I fear the process might have been
over engineered and the perfect is the enemy of the good.

Bye
Frederik
