Description:
Abstract: This dataset represents an extract from the Consolidated Database System (CDBS) licensed by the Media Bureau. It consists of Digital Television broadcasters, including noncommercial educational TV broadcast stations and, where indicated, low power TV and TV translator stations in the United States, its Territories and possessions. TV broadcast, low power TV, and TV translator stations are assigned channels 6 MHz wide (see Rule Part: 47 CFR Part 73 Rule Part, Subpart E - TV).
Purpose: This feature class 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. This dataset represents Digital Television broadcasters (see Rule Part: 47 CFR Part 73 Rule Part, Subpart E - TV).
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 ADDRESS, ZIP, ZIP+4, COUNTY, TELEPHONE (non-PII general switchboard phone number), and COUNTY FIPS, nor does it contain other attributes to indicate tower height, tower type, whether the tower is on a building, or the tower registration number. Examination of the data also reveals uncertainty about the locational information; does the value in the CITY field represent the city where the transmitter is located or the city where the licensee is located. This uncertainty produces out-of-area results, or mismatches between CITY and the geographic coordinates of the actual point of the feature. If you are using this dataset as a shapefile, please be aware that it was converted from a Geodatabase. As a result, this shapefile may have attribution and metadata errors resulting from the conversion process. The following are known issues: null values may have been changed to 0s (zeros) or to blank values, numbers (including latitude and longitude) may have been rounded up or down, there may be issues with Unicode character strings, and time cannot be stored in a date field. Field names may have been truncated to no longer than 10 characters or completely changed, lengthy string attributes may have been truncated to 254 characters, and attribute columns may have been deleted. Shapefiles do not support coded domains and subtypes therefore the original file geodatabase attribution and metadata information for coded domains and subtypes could be incorrect or missing in the shapefile version. Please visit the following ESRI website for more information: caution-http://pro.arcgis.com/en/pro-app/tool-reference/appendices/geoprocessing-considerations-for-Shapefile-output.htm
