Good math. I don't know why everyone else is assuming this photo is from a spacecraft. Virtually all of the aerial images of America on Google Earth are taken with aircraft, not spacecraft.
Interesting, but I'm not sure that is dispositive. That company is credited for images even where they are obviously aerial. Google Maps images are an algorithmic mash-up of many sources, I imagine they credit partial or possible sources conservatively, to keep from omitting any potentially relevant rights.
In many tiles they don't credit anybody, so the absences of Google's own image credit doesn't mean anything. The first party does not need to credit themselves.
