I didn’t know web satellite photos were that current. I’ve googled my neighborhood to find an entire subdivision missing. It was built four years ago.
So everyone knows... Google updates the images as it can. Some stuff are days old. Some are two-three years old. If you download the MOST RECENT version (not an older version which I have on my machine at work) then you will see some pretty updated images. Even my own house has had several images taken since 2002. There have been at least four since 2001. That means I have copies (somewhere) of them, and I can verify for a fact they were updated (ignoring the dates on them) because I know what sort of vehicles were parked at my house, like my son’s truck while he was in Iraq. However, there has not been an update since EARLY this year to some of the Colorado Springs areas. So, the images are pieced together over time, and it’s a damned big job, I’m certain.
