    <descript>
      <abstract>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.</abstract>
      <purpose>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.
