• NGA’s World Port Index rates a harbour by its area, facilities and wharf space when it was last surveyed, not by its traffic, so a busy terminal can be rated small. Where it doesn’t know about a facility it says so, and only what it marks as there is listed here.
• AIS is heard by receivers on shore, so coverage follows where they are: ships far out at sea, or off coasts without one, don’t show. Warships and some others switch it off, and a ship’s type and destination are typed in by its crew.
• Harbours from NGA’s World Port Index (Pub. 150), downloaded on Oct 19, 2026. The major ports and chokepoints are the map’s own reference list.
