Nicholas and Andre --
Chris is asking about the date of the *imagery* used for tracing, not the
date of the traced elements.
He makes an excellent point. If imagery is several years old, then
features being traced may well have changed, with the likelihood being
higher for more ephemeral human-made structures. For this purpose, would
be nice if imagery sets had metadata that included a creation date, but I'm
looking at the TMS spec, and don't see it, or any field that could be used
