Frequently Asked Questions
I do not pass any current data on to any other website*, however I do recommend that any individual contributing AIS data to ShipAIS.com also sends data to other sites, for instance
*This is partly for technical and partly for administrative reasons. There is nothing to tag who first received an AIS signal or even when so it would be easy for the same data to circle around several sites each one claiming it new data and updating the timestamp. Secondly, I would prefer to keep ShipAIS open to all and not require an "opt-in" or "opt-out" scheme for AIS data uploaders.
Old or historic data may be available for research or education purposes and for non-profit organizations.
I also make all my recorded AIS data available for accident investigations.
