Major PortsThis feature layer, utilizing National Geospatial Data Asset (NGDA) data from the Bureau of Transportation Statistics, depicts major ports in the United States and Puerto Rico by total tonnage. Per BTS, “Major Ports are politically defined by port limits or Corps projects, excluding non-Corps projects not authorized for publication. The determination for the published Major/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. The Principal Port dataset contains USACE port codes, geographic locations (longitude, latitude), names, and commodity tonnage summaries (total tons, domestic, foreign, imports and exports) for Principal USACE Ports.”Corpus Christi, TX and New Orleans, LAData currency: This cached Esri federal service is checked weekly for updates from its enterprise federal source (Major Ports) and will support mapping, analysis, data exports and OGC API – Feature access.Data.gov: Ports (National) - National Geospatial Data Asset (NGDA) PortsGeoplatform: Ports (National) - National Geospatial Data Asset (NGDA) PortsOGC API Features Link: (Major Ports - OGC Features) copy this link to embed it in OGC Compliant viewersFor more information: Port Performance Freight Statistics ProgramFor feedback please contact: Esri_US_Federal_Data@esri.comNGDA Data SetThis data set is part of the NGDA Transportation Theme Community.
