The layer represents the Strategic Highway Network (STRAHNET). The STRAHNET is a subset of the National Highway System (NHS) and includes information such as road segments, direction, build date, state codes, functional classification, ownership, and other attributes related to highways in the United States. The provided information outlines the preparation of a layer that represents the National Highway System (NHS) in the context of the HPMS 2020 Geometric network and attribute definition source HPMS 2020. The NHS layer incorporates attributes from HPMS, and the conflation process involves the transfer of State_Code, Year_Record, Route_ID, Begin_Point, End_Point, and F_SYSTEM fields. Calibration of Begin_Point and End_Point is performed based on shape length and sequence for split links. The minimum positional accuracy is specified at a spatial resolution of 1:100,000 or better, although most state-submitted data ranges between 1:5,000 to 1:10,000. The spatial data organization method is described as a vector using the SDTS (Spatial Data Transfer Standard) Point and Vector Object Type with a count of 626,366 objects. The coordinate system is defined in geographic terms with a horizontal datum of D WGS 1984, employing decimal degrees for latitude and longitude. The entity and attribute information is comprehensive, covering various aspects of the NHS and HPMS data. A data dictionary, or other source of attribute information, is accessible at https://doi.org/10.21949/1529838 The STRAHNET is an approximately 64,000 mile network of highways important for defense mobility and deployment of military equipment and personnel. The dataset exists to serve the Federal Highway Administration (FHWA) needs in highway planning, policy analysis, and visualization of the STRAHNET database. It is intended for use in understanding and managing the STRAHNET. Also, the dataset is being used by the US DOT to reflect the FHWA-approved technical correction to the STRAHNET Acknowledgment of the Federal Highway Administration (FHWA), State Departments of Transportation, and Bureau of Transportation Statistics (BTS) [distributor]. data is continually being updated Edward Starks Federal Highway Administration (FHWA) Transportation Specialist 1200 New Jersey Ave. SE Washington DC 20590 United States edward.starks@dot.gov party who can be contacted for acquiring knowledge about or acquisition of the resource data is repeatedly and frequently updated NTAD National Transportation Atlas Database Transportation Atlas Database vector line linear Roads Analysis Network Highways NHS Highway Interstate STRAHNET Strategic military DoD Department of Defense Defense mobilization Connectors STRAHNET Connectors keyword identifies a particular subject or topic none USA National United States keyword identifies a location none The NHS Version 2025.08.08 database, or any portion thereof, can be freely distributed as long as this metadata entry is included with each distribution.

Users are advised to read the rest of the metadata record carefully for additional details. The Strategic Highway Network (STRAHNET) dataset is a subset of the National Highway System (NHS) produced by querying out highways that fall under the Eisenhower Interstate System and other non-Interstate STRAHNET routes and connectors.
