Daily port and chokepoint freight flows.

Source and methods

Daily IMF PortWatch observations retained in the owner World Freight Monitor export. Calls, estimated tonnes and capacity measures remain separate; estimates are not customs-recorded cargo totals. This is a selected 356-entity, trailing 400-day export, not the complete worldwide publisher database. Missing days create gaps and zero stays zero. Exact exported numeric tokens are preserved. The owner normalization does not retain original publisher decimal formatting or row flags. Export point positions, individual file hashes, units, source layers and snapshot revision metadata remain in the JSON entity files. Revision is the maximum in that export file, not a revision flag for every point. All 839,264 exported values independently matched a read-only owner database snapshot.
