Where this comes from

  • Address matching, coordinates and census geography: the U.S. Census Bureau Geocoder. Block population and FCC market areas: the FCC Area API. Ground elevation: the FCC terrain service. NAD27 and UTM: NOAA's National Geodetic Survey (NADCON 5).
  • FM zones follow §73.205; K and W call letters follow the Mississippi River (§73.3550(e)), as do the FM translator power tables (§74.1235(b)). Within 320 km of Canada or Mexico, FM stations follow the international agreements (§73.207(b)), and translators and boosters have their own limits (§74.1235(d)).
  • Zone lines, the river and the borders are drawn from public map data and generalized, so sites close to a line are flagged to confirm.
