Description:
Abstract:
This dataset contains the spatial extent of AM tower structures in the state of Florida. AM stands for "Amplitude Modulation", which refers to the means of encoding the audio signal on the carrier frequency. In many countries, AM radio stations are known as "medium wave"(MW) stations. AM stations are also sometimes referred to as "standard broadcast stations", since AM was the first form used to transmit broadcast radio signals to the public.
Purpose:
Serve as base information for use in GIS systems for general planning, analytical, and research purposes. It is not intended for engineering work or to legally define reservation boundaries, FCC licensee data or FCC market boundaries.

Process_Description:
Data was downloaded by GeoPlan in shapefile format from the FCC website (<http://wireless.fcc.gov/geographic/index.htm?job=licensing_database_extracts>) on January, 28 2010. When received the data was in the following 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.
- Changed original file name from AM to amtow_jul09 - DESCRIPT item was added based on the item LICENSEE - FGDLAQDATE was added based on date downloaded from source

Attribute:
Attribute_Label: CLASS
Attribute_Definition:
FCC given code. The AM band frequencies are divided into three categories: Clear, Regional, and Local channels. The allowable classes depend on a station's frequency, in addition to other variables. On the Clear channels certain stations are specifically classified as Class A stations or as Class B stations. The other stations have their class determined by the frequency.

Enumerated_Domain:
Enumerated_Domain_Value: A
Enumerated_Domain_Value_Definition:
Class A station is an unlimited time station (that is, it can broadcast 24 hours per day) that operates on a clear channel. The operating power shall not be less than 10 kilowatts (kW) or more than 50 kW.
Enumerated_Domain:
Enumerated_Domain_Value: B
Enumerated_Domain_Value_Definition:
Class B station is an unlimited time station. Class B stations are authorized to operate with a minimum power of 0.250 kW (250 watts) and a maximum power of 50 kW. (If a Class B station operates with less than 0.250 kW, the RMS must be equal to or greater than 141 mV/m at 1 km for the actual power.) If the station is authorized to operate in the expanded band (1610 to 1700 kHz), the maximum power is 10 kW.
Enumerated_Domain:
Enumerated_Domain_Value: C
Enumerated_Domain_Value_Definition:
Class C station is an unlimited time station that operates on a local channel. The power shall not be less than 0.25 kW nor more than 1 kW. Class C stations that are licensed to operate with 0.100 kW may continue to operate as licensed.
Enumerated_Domain:
Enumerated_Domain_Value: D
Enumerated_Domain_Value_Definition:
Class D station operates either daytime, limited time, or unlimited time with a nighttime power less than 0.250 kW and an equivalent RMS antenna field less than 141 mV/m at 1 km for the actual power. Class D stations shall operate with daytime powers not less than 0.250 kW nor more than 50 kW. NOTE: If a station is an existing daytime-only station, its class will be Class D.

Resource_Description: DOWNLOADABLE DATA
Distribution_Liability:
The Florida Geographic Data Library is a collection of Geospatial Data compiled by the University of Florida GeoPlan Center with support from the Florida Department of Transportation. GIS data available in FGDL is collected from various state, federal, and other agencies (data sources) who are data stewards, producers, or publishers. The data available in FGDL may not be the most current version of the data offered by the data source. University of Florida GeoPlan Center makes no guarantees about the currentness of the data and suggests that data users check with the data source to see if more recent versions of the data exist.
Furthermore, the GIS data available in the FGDL are provided 'as is'. The University of Florida GeoPlan Center makes no warranties, guaranties or representations as to the truth, accuracy or completeness of the data provided by the data sources. The University of Florida GeoPlan Center makes no representations or warranties about the quality or suitability of the materials, either expressly or implied, including but not limited to any implied warranties of merchantability, fitness for a particular purpose, or non-infringement. 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: <http://geoplan.ufl.edu/education.html>
