I first saw that kind of technology in my aerospace days, around 1983. One day I was shown into a classified area, and got to try a rack of custom built special purpose hardware used for analyzing aerial imagery. There was a screen, a trackball, a knob, and a lever. Pan with the trackball, rotate the image with the knob, and zoom it with the lever. It was nicely done; no artifacts and no lag. One of the people in my department worked on extending it to larger areas of imagery, and he said it got much easier once they realized it could be viewed as a virtual memory system.

I'm not sure who the customer was. I just saw the prototype and wasn't involved with that project. At the time, imagery analysts usually used big photographs and magnifying glasses, as they'd been doing since WWII. This was the beginning of computerizing that process.

So this was being done, expensively, decades before it became a consumer product.

(DoD R&D was like that back then - very expensive one-off designs to solve specific hard problems. This was before "commercial off the shelf technology" overtook the DoD one-offs.)

my colleague in the 90s worked in Huntsville, Alabama, and if the story is true, had duties down deep in a bunker where satellite imagery was stored. People whispered it was "the whole Earth" but now we know that there are clouds :-)

interesting story however

If you're into that, NRO published a history of their early years.[1] More on the collection side than the analysis side. In the early years, it was more about collecting imagery of specific areas of interest. Now, there's a flood of imagery of the whole planet to be analyzed. NRO buys most of that from commercial vendors.

Which resulted in NRO getting flak from Congress over the rather large building complex they built out by Dulles Airport.

The plane crash on its doorstep probably didn’t help?
