Title: FCC Antenna Structure Registration for Kentucky

Abstract:

The Kentucky Public Service Commission (PSC) has downloaded and extracted the Kentucky data on Antenna Structure Registration from the Federal Communication Commission's (FCC) web site. The PSC takes no responsibility for the accuracy or completeness of the data. To promote air safety, the Federal Communications Commission (FCC) requires owners to register antenna structures more than 200 feet in height or located near an airport with the FCC. An antenna structure can be free-standing, built specifically to support or act as an antenna, or it can be mounted on another object such as a building, bridge, smoke stack, or tree. Because the Antenna Structure Registration requirements only apply to those antenna structures that may create a hazard to air navigation (either by their height or proximity to an airport), the registration files do not contain a comprehensive record of all antenna structures. Contacts for the structures are contained in a separate table that can be linked to the GIS data.

      • Entity point (1754)

   2. What coordinate system is used to represent geographic features?

      Horizontal positions are specified in geographic coordinates, that is, latitude and longitude. Latitudes are given to the nearest 0.000000. Longitudes are given to the nearest 0.000000. Latitude and longitude values are specified in Decimal degrees.

      The horizontal datum used is North American Datum of 1983.
      The ellipsoid used is Geodetic Reference System 80.
      The semi-major axis of the ellipsoid used is 6378137.000000.

   Source_Contribution:

   The Kentucky data is derived from the FCC Antenna Structure registration data files, RA (registation data) and CO (tower coordinates.) All registrations are filed via FCC Form 854.

2. How were the data generated, processed, and modified?

   Date: Whenever new data is downloaded. (process 1 of 1)

   The following procedures were performed: 1) All records were selected from the CO (Coordinates) file that had a Kentucky site address and those records were joined to the RA (Registration) file. 2) The coordinates were processed into decimal degrees NAD 83. The original coordinates were in NAD83, expressed as DD MM SS.S. However, most of the data is expressed as DD MM SS. 3) Some records were eliminated. This includes those records for coordinates for the center of an array of towers, so that just the tower coordinates are included in the database. In addition those antenna structures with a status of cancelled, terminated, or dismantled were deleted from the database. This leaves a registration database with antenna structures that have been constructed or have been granted permission for construction. 4) There are four fields for height. The data was initially recorded in meters and has been converted to feet. 5) Two tables were created: AntennaR, which contains location coordinates and structure information for each antenna, and AntContR, which includes several contacts for each structure with name, address, phone, and e-mail data. 6) Point coordinates from AntennaR were plotted as an event theme in ArcView 3.2 and converted to a shapefile.

1. How well have the observations been checked?

2. How accurate are the geographic locations?

   The coordinates were processed into decimal degrees NAD 83. The original coordinates were in NAD 83, expressed as DD MM SS.S, which means that the data base allows for a positional accuracy of plus or minus ten feet. However, most of the data is expressed as DD MM SS, so the positional accuracy is generally plus or minus one hundred feet.

3. How accurate are the heights or depths?

4. Where are the gaps in the data? What is missing?

5. How consistent are the relationships among the observations, including topology?

Are there legal restrictions on access or use of the data?

Use_Constraints:

Credit should be given to the Federal Communications Commission for the data and to the Kentucky Public Service Commission for processing. The Kentucky Public Service Commission takes no responsibility for the accuracy or completeness of the data. All critical information should be independently verified. Users should be aware that the data is downloaded periodically and may not be the most up-to-date information available through the FCC.
