Metadata.

OTOH, some locations themselves are about as anonymous as Half Dome, so geolocation is obvious. "Only one place on earth looks like that".

I generally turn off location info on the phone and cameras, though the Nikon lenses include the lens serial number in the EXIF (but not the camera body's, go figure). I suppose that this is useful in case of theft or loss.
