Description:

Abstract:

This dataset contains the spatial extent of FM Radio Station Transmitter sites in the state of Florida. FM stands for "Frequency Modulation", which refers to the means of encoding the audio signal on the carrier frequency. In some countries FM broadcast radio is referred to as "VHF." This is an update to the fmtow_jun12 layer.

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_Step:

Process_Description:

In 2012, the FCC stopped releasing its data as spatial data. Downloaded FM Towers using the FM Query Broadcast Station Search. Selected only Florida stations with an output of Text file (no delimiters / no links). Downloaded from (https://www.fcc.gov/media/radio/fm-query) in February 2017. Copied all records and pasted them into a text file. Saved as FMTOWER.txt.
- Opened and formatted FMTOWER.txt in Excel. Added field names using fmtow_jun12 and Data arrangement for Text file outputs (https://www.fcc.gov/media/radio/am-fm-tv-textlist-key). Saved coordinate fields as LATD, LATM, LATS, LATDIR, LOND, LONM, LONS, and LONDIR - Saved as .csv file - Opened .csv in ArcMap and exported to a dbase table - Added LATDD and LONDD fields using type = double. These field names were chosen to mimic the coordinate fields in amtow_jun12. - Used field calculator to convert coordinate fields from DMS to DD. The equation for latitude (LATDD) was: ( [LATS] /3600) + ( [LATM] /60) + [LATD] The equation for longitude (LONDD) was: ( [LONS] /3600) + ( [LONM] /60) + [LOND] - Generated XY data using the LATDD and LONDD fields. The projection used was defined as WGS 1984. Projected the event layer to Albers_Harn using project tool and exported out as shapefile - Deleted fields not present in fmtow_jun12 - Added descript field based on LICENSEE - Added FGDLAQDATE based on the date GeoPlan acquired the data - Added a LAT and LON field based on combination of LATD, LATM, LATS, LATDIR, LOND, LONM, LONS, and LONDIR then deleted those field because they are not present in the previous FMTOW shapefile - Restructured table and uppercased all fields
Note: When the FCC generated this data set spatially in the past they limited the lat/long fields to 4 decimals. Now that we are generating the spatial locations the decimals have been left to the default value of the field type of double. The result is a visible shift of 30-36 meters.

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>
