USER NOTES:
This dataset contains informatin on Intermodal Terminal Facilities (facilities that support two or more modes of transportation) from the U.S. Department of Transportation, Bureau of Transportation Statistics (BTS), National Transportation Atlas Database (NTAD) 2003. An Intermodal facility is defined as generalized descriptors for collated customers and services. The table contains facilities that support two or more modes of transportation. These facilities can contain an address, but must contain a latitude and longitude. A single coordinate pair for GIS reference represents all points. A unique id number relates the records to other tables. A parent id is required, which may be used to aggregate to its facility, which is the granularity of the publicly released data. All records require geocoding, mode type, facility type, unique name combination, and unique id to be included in the final dataset. Geocode source holds the source of the spatial coordinates, particular sources have varying spatial accuracy and is noted below. GDT98Streets - 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. For more detailed information please see Geographic Data Technology Inc. 1(800) 331.7881 or email to info@gdt1.com 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 A note concerning data scale: Scale is an important factor in data usage. Certain scale datasets are not suitable for some project, analysis, or modelling purposes. Please be sure you are using the best available data. 1:24000 scale datasets are recommended for projects that are at the county level. 1:24000 data should NOT be used for high accuracy base mapping such as property parcel boundaries. 1:100000 scale datasets are recommended for projects that are at the multicounty or regional level. 1:250000 scale datasets are recommended for projects that are at the regional or state level or larger. Vector datasets with no defined scale or accuracy should be considered suspect. Make sure you are familiar with your data before using it for projects or analyses. Every effort has been made to supply the user with data documentation. For additional information, see the References section and the Data Source Contact section of this documentation.

FGDL QUALITY ASSURANCE STATUS:
Process Steps for NTAD 2003 Intermodal Facility Locations: -Intermodal Facility locations were obtained from the CD-ROM National Transportation Atlas Database (NTAD) 2003 (A Collection of Spatial Data for Use in GIS-based Applications) BTS-03-04. -GeoPlan extracted this data in shapefile format and removed facilities not located in Florida. -Three tables were also joined to the shapefile through the Facilities ID number. -The shapefile was reprojected from WGS_1984 Decimal Degrees to the FGDL Albers HPGN map projection. (See "Map Projection Parameters" below).
