Quote Jörn KH:
Did not test it, but perhaps it could be possible with a combination of requests:
One request with set=all, a second request with set=public and afterwards a comparison of both.
Edit: Sorry, with this you will get NOT selected and NOT mapped too.
Thanks Jörn KH. I was thinking along those lines too - but the majority of our group submissions are mapped for selection in GE and were rejected... the Beautiful Rejects group. We actually are looking for a way to create a specialized set and send Invites.
It seems possible to be exact because lots of my photos include the notation...
"This photo is not selected for Google Earth [?] - ID: ##### [ Ask for a second review ] Delete"
.... and that is exactly what we are looking to collect into a set.
Thanks again. Any other thoughts?
