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.

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.

DATA LINEAGE SUMMARY:

In 2012 the FCC stopped releasing tower and antenna locations as spatial data. Data layers are available as databases with associated .dat files. GeoPlan downloaded FM towers using the FM Query Broadcast Station Search. Selected only Florida stations with an output of Text file (pipe delimiters / no links). Downloaded from (https://www.fcc.gov/media/radio/fm-query) in August 2019. Copied all records and pasted them into a text file. Saved as fmtow.txt. During the QA/QC process GeoPlan performed the following steps: - Opened and formatted the fmtow.txt in Excel and saved as a CSV. Exported the CSV to a .dbf file using ArcMap. Added field names using previous fgdl versions and the Data arrangement for Text file outputs file available at (https://www.fcc.gov/media/radio/am-fm-tv-textlist-key). Saved coordinate fields as LATD, LATM, LATS, LAT_DIR, LOND, LONM, LONS, and LON_DIR - Added LAT and LONG fields using type = double - Used field calculator to convert coordinate fields from DMS to DD. The equation for latitude was: ( [LATS] /3600) + ( [LATM] /60) + [LATD] The equation for longitude was: ( [LONS] /3600) + ( [LONM] /60) + [LOND] - Generated XY data using the LATDD and LONDD fields. The projection was defined as WGS 1984. - Exported XY events to shapefile. - Fields LATD, LATM, LATS, LAT_DIR, LOND, LONM, LONS, and LON_DIR were deleted. - A number of records fell outside the boundaries of Florida. These records were left as is. - Projected the new shapefile to NAD83 HARN using the WGS_1984_(ITRF00)_To_NAD_1983 + NAD_1983_To_HARN_Florida transformation - Edited the feature class attribute table to match previous fgdl versions. - Added field MGRS by using the Convert Coordinate Notation tool and choosing output coordinate format as MGRS. - Added field GOOGLEMAP by concatenating: https://www.google.com/maps/place/ and the MGRS ID - Added descript field based on LICENSEE. - Added FGDLAQDATE based on the date GeoPlan acquired the data - Restructured table and uppercased all fields Notes: 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.
