Brings to mind the story in December 2022 about confirming the B-21 hangar location from the night sky in a press photo (https://news.ycombinator.com/item?id=33912401 https://news.ycombinator.com/item?id=33912401). Not enough of the sky for that here though. Wonder if folks in this space have a more automated process to recognize the landscape rather than "Hella scrolly scrolly on Google Earth"...
- zh3 4y agoPublish it widely enough and someone will recognise the terrain (especially with things like reservoirs visible). To automate it, trace the outline of bodies of water and compare to public data, e.g. SRTM [0]? Lots more detail (and a good jumping-off point) on the wikipedia 'Imagery Intelligence' page [1].
