Interesting, I like the overlay. If you want a decent read on this topic, get Podvig's book. It'll run you around $50 USD, but it's well worth it.

Personally I hope we get more high-rez coverage of the area around Moscow. I've already plotted all the old S-25 (SA-1 GUILD) SAM sites (search for the thread, they haven't been put into the database yet apparently) and located two S-300P SAM sites around Moscow, and I'd be willing to bet that a good deal of these old S-25 sites are now home to S-300P SAMs.

Plus, I'd love another high-rez look at Zhukovskiy flight test center and the museum at Monino

Also, I've got ballpark locations for the GORGON launch sites, but need some decent high-rez imagery to clarify their actual positions. I've got the main radar sites including PILL BOX located as well, those are large enough to discern in low-rez imagery. I think those are in here somewhere too.
