system where poorly charted areas eventually get fully covered and are kept up to date. Keep it up!
has been around a long time & does exactly this, it's a commercial product & ain't cheap, a full system is about 10 grand
It is VERY impressive though. Users upload their data & share it with other users, the result is that you get very detailed topographical maps of the sea floor, as long as you're in an area that's been well covered. I've seen it in operation on dive boats combined with a multibeam sonar & the detail is incredible.
