Unless there is a requirement that anything mapped by aerial imagery must
be compared in two independent sets of imagery, I don't see a problem. We
have aerial imagery of these (but whether or not it is ever made available
us under appropriate copyright terms is another matter). Verification is a
matter of somebody else looking at the same imagery and reaching the

I doubt the imagery will be released in a form we can use. But it might be.

I wouldn't map vegetation discolouration as indicative of anything because I
don't have the expertise to tell what it means. But if experts at a
heritage organization determine that the discolouration is the result of a
historical feature and designates it as a nationally important
site then I might map it as such (that designation would put it under legal
protection and it would be a criminal act to dig it up).
