USER NOTES:
The Fixed-Guideway Transit and Ferry Network is a comprehensive network database of the nation's fixed-guideway transit and ferry systems. The data set covers systems in cities within the 48 contiguous States plus the District of Columbia and Puerto Rico, and includes heavy rail, light rail, monorail, ferry boat, cable car, dedicated HOV roadway, inclined plane, and automated guideway. The data provide users with information about the location and type of fixed-guideway transit and ferry network and terminal facilities primarily for regional cartographic, spatial and network analysis purposes. The dataset provides location and attribute information for use in national and regional cartographic and network analysis applications. 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 multi-county 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:
-Projected data to FGDL Albers HPGN (See "Map Projection Parameters" below). -Clipped to the State of Florida -DESCRIPT item already present -Upcased all character records
DATA LINEAGE SUMMARY:
This data was originally released by U.S. Department of Transportation, Bureau of Transportation Statistics in 2001. In 2002, the GeoPlan Center downloaded this data in shapefile format from the Bureau of Transportation Statistics website (http://www.bts.gov/gis/ntatlas/networks.html). When received, this data was in the following projection: Geographic, Datum: NAD 83, Spheroid: GRS80, Units: Decimal Degrees. The shapefile was projected to FGDL Albers HPGN (See "Map Projection Parameters" below), and clipped to the State of Florida boundary.
