AIS is the first thing nefarious vessels turn off when they do nefarious things. Or set it to show 100-1000 km off, AIS protocol is easy.

One could combine it with satellite imagery and flag up anything where the ais data and satellite imagery doesn't show a ship in that place.

Ships are big enough that even low Res imagery ought to be able to see them in daylight.

I was commenting on the link posted.

"Could be" of course many things better. The webmasters could launch their own satellites.
