Description
The Principal Ports dataset is periodically updated by the United States Army Corp of Engineers (USACE) and is part of the U.S. Department of Transportation (USDOT)/Bureau of Transportation Statistics (BTS) National Transportation Atlas Database (NTAD). The Principal Ports are politically defined by port limits or Corps projects, excluding non-Corps projects not authorized for publication. Principal Ports are the top 150 U.S. ports based upon total annual tonnage. Variation in annual tonnage at a port may result in exclusion or inclusion on the Principal Port list. The Principal Port dataset contains port codes, port names, geographic locations (longitude, latitude), and commodity tonnage summaries (total tons, domestic, foreign, imports and exports).
