资源简介:
Communication antenna towers registered with the U.S. Federal Communications Commission's Antenna Structure Registration (ASR) program. The FCC requires that all towers >200 ft tall and towers <200 ft that are positioned in the glide path of an airport be registered with the FCC ASR program. Therefore, this data set does not necessarily depict ALL communication antennas actually present on the landscape. The source data are updated weekly by the FCC as new permits are issued. However, this data set is designed for a specific analysis, and is planned to remain static as of the publication date (11/06/2003).
