Network
How central Annaba sits in the sea-route network we cover: a connectivity score across navigable distances. A higher score means the port is navigationally close to many other well-connected ports, the maritime signature of a hub.
Directly routable to 349 other covered ports.
Method. A connectivity score across our own route network: a port reads higher when it is navigationally close to many other well-connected ports. The score is rescaled 0 to 100 within the snapshot, so the single most-connected port reads 100. Distances are Suez / Panama / Malacca-aware navigable sea miles.
Coverage. The route network spans the 350 largest commercial ports, so this ranks hubs within that covered network, not against every port on earth. The number is deterministic. No confidence grade is invented. Computed Oct 12, 2026.
