A lot of time and money is spent on mapping high use lanes and ports. But everything else is probably charted long before GPS.
If you take sat photos and superimpose them onto drawn charts, its shocking how bad charts really are. Im surprised there aren't nautical charts based entirely off of satellite imaging. I would pay good money for that.

There are if you want to pay for it. My Garmin radar, sounder, GPS bundle can interface and overlay satelite imagining onto my chart plotter. I don't pay for that service so I down load charts to my plotter. It's amazing how off the digital files are so I still use paper charts and a compass with the elctronics to verify.
