Description:
Abstract: This dataset represents Land Mobile Commercial transmission tower locations as recorded by the Federal Communications Commission, extracted from the FCC Licensing Database. This serves 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 FCC licensee data or FCC market boundaries. The material in these data and text files are provided as-is. The FCC disclaims all warranties with regard to the contents of these files, including their fitness. In no event shall the FCC be liable for any special, indirect, or consequential damages whatsoever resulting from loss or use, data or profits, whether in connection with the use or performance of the contents of these files, action of contract, negligence, or other action arising out of, or in connection with the use of the contents of these files. It is know that there are some errors in the licensing information - Latitude, Longitude and Ground Elevation data as well as frequency assignment data from which these files were generated.
Purpose: This dataset represents Land Mobile Commercial transmission tower locations as recorded by the Federal Communications Commission, extracted from the FCC Licensing Database.
Supplemental Information: Caution should be exercised by the user of this feature class. This feature class does not contain fields of attribution for MEDS attributes of ZIP, ZIP+4, TELEPHONE (non-PII general switchboard phone number), and COUNTY FIPS. The following fields are only partially populated with actual values beyond “NOT AVAILABLE” (or blank): QZONE: 1% (this is likely a correct population of the value, but this cannot be adequately determined on the lack of adequate explanation in the metadata), TOWREG: 20%, STRUCTYPE: 84%, NEPA: 61%. LOCADD information is largely directional or locational, rather than an actual address. This layer also includes 11 records that appear to have erroneous locations in the Atlantic Ocean and Pacific Ocean.

Process Description:
Updated the locations of four points by updating incorrect negative sign information. Standardized letter casing, fixed spelling, and removed included states in the LOCCITY field. Standardized letter casing, abbreviations and punctuation in the LICENSEE field. Standardized letter casing, spelling, abbreviations and punctuation in the LOCSTATE, LOCADD, LOCCOUNTY, and LOCCITY field. Updated incorrect entries in the LATDIR and LONDIR fields. Standardized capitalization in the STRUCTYPE field. Updated blank attributes in the LOCCOUNTY field to 'NOT AVAILABLE'. Updated blank attributes in the LOCADD field to 'Not Available'. Updated blank attributes in the QZONE, STRUCTYPE and TOWREG fields with 'N/A' due to character restrictions. Updated Gulf of Mexico entries in the LOCCOUNTY field to 'NONE'. PII removed from metadata.
