BY-SA doesn't require a copyright notice. It requires keeping intact
copyright notices that are provided, as well as license notice. Given
that copyright is automatic, many licensors don't provide the former,
though it may be useful to do so anyway for education. The notices
provided by CC don't include an explicit copyright notice.

It seems to me space is at a premium in the corner of a map or a
caption, and spelling out doesn't gain much, but that's just my
opinion.

Just as an experiment in brevity

©OpenStreetMap data ODbL[ tiles BY-SA]

With "OpenStreetMap", "ODbL", and "BY-SA" linked to the obvious
places, [] when tiles used.

That's the oddest thing I've read today. Really?

Nobody has ever sent a request for a copy of a license via post,
AFAIK. :) But the full license URL should be provided, not
"www.creativecommons.org". Same is true of ODbL which says "If
hyperlinks are not possible, You should include the plain text of the
required URI’s with the above notice."
