This is very informative. How are the vessels tracked? Is this real-time tracking of specifically equipped vessels. Can any other vessels be tracked or only those with traditional maritime transponders? If real-time, it'd be cool to have vessel/point data be displayed upon hovering over with a mouse.
Ships over a certain size are obligated to report their position (and some other information) over AIS (similar to ADSB on airplanes. It's meant for other nearby ships and ports for navigational purposes. These are tracked from shore based scanners, scanners on ships and satellites. You can see partly real-time data on marinetraffic.com and vesselfinder.com
Thank you :)
