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.Data was downloaded on October 15th, 2012, the last update of the Principal Ports was 5/31/2012 9:49:00 AM. |
