USACE works with port authorities from across the United States to develop the port boundaries through an iterative and collaborative process. Port boundary information is prepared by USACE to increase transparency on public waterborne commerce statistic reporting, as well as to modernize how the data type is stored, analyzed, and reported. A Port Area is defined by the limits set by overarching legislative enactments of state, county, or city governments, or the corporate limits of a municipality. A port typically refers to a geographical area that includes operational activities related to maritime transport as well as acquisition, operation, and management of port infrastructure and property, such as might be associated with ownership, concession, construction approval, or policy decision-making authority. Per Engineering Regulation 1130-2-520, the U.S. Army Corps of Engineers' Navigation Data Center is responsible to collect, compile, publish, and disseminate waterborne commerce statistics. This task has subsequently been charged to the Waterborne Commerce Statistics Center to perform. Performance of this work is in accordance with the Rivers and Harbors Appropriation Act of 1922. Included in this work is the definition of a port area. A port area is defined in Engineering Pamphlet 1130-2-520 as: (1) Port limits defined by legislative enactments of state, county, or city governments. (2) The corporate limits of a municipality. The USACE enterprise-wide port and port statistical area feature classes per EP 1130-2-520 are organized in SDSFIE 4.0.2 format. A data dictionary, or other source of attribute information, is accessible at https://doi.org/10.21949/2ngc-4984 The Port Areas web service allows users to visualize and access the USACE enterprise-wide Port Areas Feature Class, which includes polygon geometries used to generate statistics for commerce data and vessel movements. The GIS service includes attributes such as port name, boundary description, and associated legislative documentation.

Users are advised to read the rest of the metadata record carefully for additional details. The U.S. Army Corps of Engineers’ (USACE) Navigation and Civil Works Decision Support Center (NDC) is proud to offer a Geographic Information System (GIS) public web service for port areas. Per Engineering Regulation 1130-2-520, the port area polygons are defined by legislative enactments of state, county, or city governments, or corporate limits of a municipality. USACE’s NDC works with port authorities from across the United States to develop the statistical port boundaries through an iterative and collaborative process. The GIS service includes attribution on port name, boundary description, and associated legislative documentation. The primary use of the new GIS layer is for public reporting on waterborne commerce statistics related to tonnage and commodity types, which USACE’s Waterborne Commerce Statistics Center (WCSC) performs annually. Port boundary information is prepared by USACE to increase transparency on public waterborne commerce statistic reporting, as well as to modernize how the data type is stored, analyzed and reported. The port boundary GIS file allows users to visualize each statistical port, and it can be combined with other dock and vessel statistics compiled by USACE, the U.S. Census Bureau and the U.S. Customs and Border Protection. The statistical port boundary file is designed in accordance with the U.S. Department of Defense’s Spatial Data Standards for Facilities, Infrastructure, and Environment (SDSFIE).
