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.

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. For more information regarding scale
and accuracy, see our web pages at:

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).
