Actually it's very well known in terms of MASIN and GEOINT. I once even interviewed with them back in the day, and they don't do a lot to hide their presence. I think they're not in the news a lot because what NGIA does and what Google and a lot of private satellite imagery companies do, is really the same.

As a point of reference, NGA is the National Intelligence Manager (NIM) for GEOINT, while DIA is the NIM for MASINT.
