I've been exploiting Terra Server, Bing Maps, and a few other amusing online imagery sources to examine some areas of Google Earth that are either 1) not covered in high resolution, or 2) have not been updated with newer imagery for quite some time. I've discovered a number of things that will be included in the SAM Site Overview, beginning with the next update. This might be a little confusing at first glance. For example, I've found imagery from 2009 showing that the 64N6E site in China near Dalian is now active. I will be changing the placemarks in the file to reflect this, as Google Earth's imagery of that region is still a bit dated. So, you'll see an empty 64N6E location, but have a placemark telling you that it is active. No, I haven't lost my mind, I'm just beginning to incorporate other sources into the database on a larger scale. Anything potentially weird like that example will always be explained in the Notes section of the placemark. Just thought I'd give everyone a heads-up before I start doing something potentially confusing.
