I read somewhere, probably on Google, that the satellite data is used by measuring the height of the ocean and then using that information to infer
the topography of the ocean floor. It is a technique that yields results much less accurate than sonar. Based on my experience in geology and reading
satellite imagery, this is a reasonable explanation. I am a very cynical person, but I don't see this statement as at all unbelievable.
I have looked at some images of water just offshore from land and you can see the bottom and get a good idea of the topography in some places, but as
soon as the water is a certain depth, you can't see anything. I would be surprised if one can see beyond 30 meters (98 feet). Also, there are
different types of imagery such as infrared which gives a different look at things, but I know nothing about that.
