- Description:

- Abstract:
- The BASINS Federal Highway Administration Major Roads data product was derived from the National Highway Planning Network, a comprehensive network database of the nation's principal arterial highway system and other National Highway System routes. The data set covers the 48 contiguous States plus the District of Columbia. The nominal scale of the data set is 1:100,000 with a maximal positional error of 80 meters.
- Purpose:
- This geographic dataset was prepared to serve as a reference background map for the USEPA BASINS (Better Assessment Science Integrating Point and Nonpoint Sources) GIS system.
- Supplemental_Information:
-
Data in ArcInfo coverage format were obtained from U.S. Department of Transportation, Bureau of Transportation Statistics internet site at The National Highway Planning Network.
Individual state coverages were projected to geographic decimal degrees, NAD83.
For distribution with BASINS v2.0, state coverages were MAPJOINed then CLIPed to the extent of each of the nine U.S. EPA Regions, plus the hydrologic accounting units that crossed Region boundaries. The coverages were then converted to ESRI Shapefile format, using the ARCSHAPE command.

- The elements of the NHPN have been conflated to the 1:100,000 DLG-3 data set which maintains a nominal accuracy of at least 80 meters. Where new roads have been added which are not in the DLG-3 database link alignments have been digitized or converted from digital sources acquired from State DOTs with a map scale of at least 1:100,000.

- Composite field of SIGNT1, SIGNN1, and SIGNQ1 The SIGNT1 field is followed by a left-adjusted sign route number (SIGNN1) for the route. The SIGNR field can contain alpha characters to allow for actual sign route numbers such as route A1A in Florida. Using HPMS standards, an optional directional indicator (N, S, E, W) can also be used as part of the SIGNN1 field. The Sign Route Number is followed by an optional Sign Route Qualifier Record (SIGNQ1) which is used to qualify the sign route description subfield SIGNT1.
