Every Seaport on Earth

The world’s harbours on one map: 3,804ports the global shipping network actually uses — from the deep-water mega-ports that handle the biggest container ships down to the small coastal and river harbours — across 193 countries. Each point is coloured by harbour size, so the great gateways stand out from the thousands of minor ports around them. Data is public-domain from the NGA World Port Index, a snapshot taken 2026-06-22.

What the colours mean

Every port is tinted by its harbour size— a rating in the World Port Index for the scale of the harbour and the vessels it can take. Amber marks the large deep-water ports, the ones that handle the biggest ships. Charge-blue is medium ports, radar-green is small, and a dim slate is the very small harbours that make up the bulk of the index. What that rating means, and why a tiny country can run a giant port, is worth two minutes:

About this data

Port locations, names and harbour sizes come from the World Port Index (Pub 150), the U.S. National Geospatial-Intelligence Agency’s global register of ocean and major inland ports — a public-domain reference used in marine navigation. The size rating reflects the physical scale of each harbour, not its cargo throughput, so a busy container terminal and a large naval harbour can share a rating. This is a dated snapshot of where ports are, not a live ship-tracking feed (for vessels under way, see the live ships overlay on the Earth canvas). We refresh the snapshot periodically rather than calling NGA on every visit.
