1. Vessel positions - commercial AIS feed

Through the dayLicensedAIS
Positions come from a commercial AIS service, collected through this site's own server and logged in a daily snapshot. AIS shows where a vessel is, her status and what her crew has entered in the destination box.

2. Fields and ports - outlines checked by hand

Public sourcesCorrected as found
Field and port outlines are built from public sources and corrected when a vessel or a reader shows them wrong. Where we hold no outline, a working vessel reads as on passage, and we say so.
