That is a pretty cool google map application.
I had done similar many years ago but the Google API has been updated twice since then (breaking about 1000 hours of work)
Here are some examples I saved.
CONUS Unit locations
UK nuke strikes
US helium refinering locations (different map tool)
Galvinston Fallout patterns (yes I looked up historical weather for Late Nov 1997)
If anyone wants the data let me know.
