please also note that there is orthoimagery from the PCN available for the
whole of Italy. This is typically better aligned than Bing.

Hi Martin,
I am planning to review the objects systematically, and sometimes the
tagging doesn't give much information. Also, as we know, sometimes an
object is added, but the accuracy may not be that high.
So - when I review an object (with no source information provided in the
tags), and can

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

I guess I am looking for something like
- http://wiki.openstreetmap.org/wiki/Key:survey:date
- http://wiki.openstreetmap.org/wiki/Key:check_date
but for satellite image cross-check (unlike survey:date, which is for
verification in person).

Hi all,
how would you tag whether an archaeological site is visible on satellite
images?
Sardinia has several 1,000 large megalithic stone towers (nuraghe), about
600 of which are in OSM. However, they have different states of
preservation. Some are clearly visible on the satellite image (with
