Military Special Use Airspace is airspace of defined dimensions identified by an area on the surface of the earth wherein activities must be confined because of their nature, and/or wherein limitations may be imposed upon aircraft operations that are not a part of those activities (FAA Order 7610.4K CHG 1, Section 1.3). Limitations may be imposed upon aircraft operations that are not a part of the airspace activities. Special use airspace includes any associated underlying surface and subsurface training areas. The types of SUA are Special Use Airspace (SUA), Alert Area, Controlled Firing Area, Military Operating Area (MOA), Special Operation Area (SOA), Prohibited Area, Restricted Area, Warning Area and Altitude Reservations (ALTRV). DoD Special Use Airspace (SUA) from the NGA Digital Aeronautical Flight Information File (DAFIF). The MarineCadastre.gov team worked with the Navy to provide this data, which is a subset of the Navy's Common Operating Picture, for ocean planning purposes. This data was derived from the Navy Common Operating Picture data which was downloaded on August 11, 2017. Any questions about access to or the content of the data should be directed to the Navy at eims_usersupport@navy.mil.

The Port Statistical Areas dataset was updated on June 05, 2025 from 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). USACE works with port authorities from across the United States to develop the statistical 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 Statistical Area (PSA) is a region with formally justified shared economic interests and collective reliance on infrastructure related to waterborne movements of commodities that is formally recognized by legislative enactments of state, county, or city governments. PSAs generally contain groups of county legislation for the sole purpose of statistical reporting. Through GIS mapping, legislative boundaries, and stakeholder collaboration, PSAs often serve as the primary unit for aggregating and reporting commerce statistics for broader geographical areas. 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

This feature class was extracted from the RealProperty\Site_A feature class of the Spatial Data Standards for Facility, Infrastructure and Environment (SDSFIE) 3.0 data model.

Military regulated airspace areas depict the Air Traffic Control Assigned Airspace (ATCAA) and Airspace Corridor areas.

An Operating Area (OPAREA) Complex boundary is the bounded area in which national defense training exercises and system qualification tests are routinely conducted. OPAREA boundaries are formally established by national designation and by international treaty for national defense training purposes, and allow for specific exercises and training events to be coordinated with other federal, state, and local agencies, and also the general public, as in Notices to Mariners (NOTMARS). Includes the OPAREA, range complex boundaries and study areas.

USACE works with port authorities from across the United States to develop the statistical 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.

The Port and Port Statistical Area web service allows users to visualize and access two USACE enterprise-wide feature classes: the Port Feature Class and the Port Statistical Area Feature Class, both of which include 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.
