Default AIS ship data: everibody have seen this? - why do we use GPSto track buoys??

Now that we have GPS, why are buoys needed anymore? Aren't you really
interested in where the channel is located and not the location of some buoy
that also happens to be trying to show you where the channel is located?
When did buoys become a destinatiion in and of themselves instead of merely
a source of nautical information guiding us around underwater obstructions?


Let me ask, have you ever actually spent any time doing coastal
navigation? And if so, what navigation resources were available to you
and which ones did you use?
