Description
Abstract
This is a public dataset for the Department of Transportation, Research and Innovative Technology Administration's Bureau of Transportation Statistics. The public database consists of four tables. One of the tables is a spatial table: INTERMODAL_FACILITY. The three other tables consist of attribute data for the database: INTERMODAL_CARGO, INTERMODAL_COMMODITY and INTERMODAL_DIRECTIONALITY. This database was based on the requirements from the Commodity Flow Survey and with the different modes of DOT, supervised by RITA/BTS. The database will extend its design to support all of the modes within the DOT and in reference to modes involved with Intermodal transfer.
Purpose
This is a public dataset for the Department of Transportation, Research and Innovative Technology Administration's Bureau of Transportation Statistics for internal use in GIS efforts. The data can be utilized alone or in conjunction with various networks developed for the data.

Process step 1
Process description: The use of this data for network or attribute related queries should note that supplementary data is stored in a separate dbf files. These tables hold pertinent information in a relational database format, ID fields being linked as the primary keys and foreign keys. PU_FAC table's primary key is ID and is the foreign key in PU_CAR, PU_COM, and PU_DIR, identified by FAC_ID.
The shape files match the corresponding dbf files, no conversion is needed to utilize either format for analysis. Data is based on various public and private published sources, i.e. IANA Railway Guide, WWW, Army Corps of Engineers - Port Report. These sources are frequently updated and revised, any particular inquires should be directed to the data source of the record or records.

Spatial data quality
Horizontal positional accuracy
Geocode source holds the source of the spatial coordinates, particular sources have varying spatial accuracy and is noted below.
Estimated accuracy: 1:100,000
How this value was determined:
GDT98Streets:
- The original digital source of line segment, such as a Census Bureau 1980 GBF/DIME File or a USGS 1:100,000 scale DLG-3.
- Scale 1: 24,000
- For line segments that originated with the USGS DLG-3 files, the FCC is based on the USGS classification code in the DLG-3 file. For line segments that originated with the 1980 GBF / DIME Files, the FCC is based on the NS code and other feature identification content of the GBF/DIME -File.
- Latitude/longitude Data: except for DIME format (ASCII) boundary files, all latitude and longitude coordinates are signed and have six decimal places. Northern latitude is positive (0 degrees to 90 degrees), southern latitude is negative (0 degrees to -90 degrees). West longitude are negative (0 degrees to -180 degrees), and longitude are positive (0 degrees to 180 degrees)
- DIME format boundary file coordinates are expressed as all positive values with six implied decimal places. Any longitude west of 180 degrees is expressed in increasing, rather than decreasing values.
Projection using latitude/longitude coordinate values with an implied 6 decimal places
All coordinates are based on the 1983 North American Datum (NAD83).
- As new streets are reported, they are added daily by digital map technicians (DMTs) working in teams assigned to specific geographic areas covering the entire nation. As DMTs work through their particular regions, they concentrate on areas that contain the largest numbers of missing addresses, usually newly developed areas. They apply address ranges to unaddressed street segments, digitized new streets, correct inaccurate segment shapes, and add exits and turn or one-way restrictions. Each addition is verified with current maps and other data.
- ARC/INFO format products are available in double precision. Precision refers to the number of bits (single - 32bits, double - 64 bits) used to store coordinate data. Coverages in double precision are slightly more accurate, but larger than those in single precision.

Estimated accuracy: 1:
How this value was determined:
Army Corp of Engineers
Estimated accuracy: 1:
How this value was determined:
Airport attributes were obtained from the Federal Aviation Administration's (FAA) National Airspace System Resource Aeronautical Data and the Office of Airline Information (OAI) Enplanement Data. The FAA Data was published by the Aeronautical Information Services (ATA-100) with an Effective Date of 21 February 2002.
Horizontal positional accuracy is based on coordinate data provided in the FAA National Airspace System Resource Aeronautical Dataset (Effective 21 February 2002). These coordinate data identify the approximate location of the Airport Reference Point (ARP) as reported by the landing facility on the NFDC (National Flight Data Center) 5010 form. According to NFDC guidelines, the location of the ARP should be reported to a horizontal accuracy of one arc second of latitude and longitude. However, the accuracy of these reported coordinates are not verified by FAA. The records were loaded into a GIS and checked for any unusual or obviously erroneous locations.
