CALLSIGN A combination of letters and numbers that identify an FCC license.

SERVICE Service provided by structure
CA = Class A TV

DC = Undefined by Source

DT = Digital TV

LD = Undefined by Source

TV = Television

TX = TV Translator or LPTV station

USER NOTES:
This data is provided 'as is'. GeoPlan relied on the integrity
of the original data layer's topology
This data is provided 'as is' by GeoPlan and is complete to our
knowledge.
GeoPlan relied on the integrity of the attribute information within
the original data.
The previous version of this dataset varies greatly from the present version. 
Both the attribute table and feature count are quite different. These changes
are due to a change in the way the FCC keeps this information in their database.

The data was created to serve as base information for use in GIS systems 
for a variety of planning and analytical purposes.

This data is provided 'as is' and its horizontal positional accuracy
has not been verified by GeoPlan

This data is provided 'as is' and its vertical positional accuracy
has not been verified by GeoPlan

THE DATA INCLUDED IN FGDL ARE 'AS IS' AND SHOULD NOT BE CONSTRUED
AS LEGALLY BINDING. THE UNIVERSITY OF FLORIDA GEOPLAN CENTER SHALL
NOT BE LIABLE FOR ANY DAMAGES SUFFERED AS A RESULT OF USING,
MODIFYING, CONTRIBUTING OR DISTRIBUTING THE MATERIALS.

A note about data scale: 

Scale is an important factor in data usage.  Certain scale datasets
are not suitable for some project, analysis, or modeling 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.
1:125000 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 analysis. 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 webpage at:

DATA LINEAGE SUMMARY:
This data was originally released by the Federal Communications
Commission in November 2007 as two separate files, tvntsc.shp 
(analog structures) and tvdigital.shp (digital structures).The original 
data contained data for the entire United States. 

Data was downloaded from the Federal Communications Commission 
website (http://wireless.fcc.gov/geographic/index.htm?job=licensing_database_extracts)
in shapefile format in March 2008.  When received the shapefiles
were in the projection: Geographic,  Datum: NAD 27, Spheroid: Clarke1866, 
Units: Decimal Degrees. Points for only the State of Florida were exported 
using the selection "STATE" = 'FL' and the data was projected to FGDL 
Albers HPGN. The analog and digital structure shapes were merged and
a TYPE field was added denoting whether the structure is either "DIGITAL"
or "ANALOG."

1 point was inside Florida but had STATE = AL. This point was kept in layer.
FILENUM = BMLCT  -20030502ACB

6 points were outside of Florida but had STATE = FL. These points were deleted
FILENUM =
BLCT   -20040316ADP
BLCT   -20070604ACF
BLCT   -20030129AKX
BLCDT  -20060627AAV
BLCDT  -20021025ABG
BLEDT  -20060621AAS

- The original dataset names were tvntsc and tvdigital
- The dataset was projected data to FGDL Albers.
- Added the FGDLAQDATE field based on date downloaded from source
- Added DESCRIPT item based on CALLSIGN.
- All fields were upcased.
