Abstract
The Principal Port file contains USACE port codes, geographic
locations(longitude, latitude), names, and commodity tonnage
summaries (total tons, domestic, foreign, imports and exports)
for Principal USACE Ports.
The ports are politically defined by port limits or Corps projects,
excluding non-Corps projects not authorized for publication.
The determination for the published Principal Ports is based
upon the total tonnage for the port for the particular year;
therefore the top 150 list can vary from year to year.
