Hi Martin, hi Marc,

thanks for the response. I suppose another way of looking at it would be to
say that the site's existence is verifiable from satellite images. Is there
a tag for that? It could always be added to the note tag, but a structured
tag may be better. E.g. "visible:bing2012=1" or "verified:bing2012=1".

Alternatively maybe "source=bing' would also be ok? Strictly speaking, bing
may not have been the source, as the data may come from a ground survey.
But would it be reasonable to add "source=bing" if the structure is visible
on bing? I suppose "verified:bing2012" may be clearer, and avoid confusion?

Btw. I'm not proposing a new tag, just seeing whether there is an existing
tag I can use.
