W., S. T. Knick, M. A. Schroeder, and S. J. Stiver. 2004. Conservation assessment of Greater Sage-grouse and sagebrush habitats. Western Association of Fish and Wildlife Agencies. Unpublished Report. Cheyenne, Wyoming. Online_Linkage: http://sagemap.wr.usgs.gov/ Description: Abstract: Communication antenna towers recorded by the U.S. Federal Communications Commission's International Bureau Filing System (IBFS) - 47 CFR Parts 73/74, 23 and 25 (Earth Stations). Note that not all antennas and towers are required to be registered with the FCC. Therefore, this data set does not necessarily depict ALL communication features actually present on the landscape. The source data are updated daily 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). Purpose: This spatial data set was initially developed for use on the Rangewide Conservation Assessment for Sage Grouse, but the data set has general use applications. Supplemental_Information: There are known (and obvious) spatial errors. Some antennas are mislocated in the source data.

The true accuracy of the remaining features is unknown and untested. Logical_Consistency_Report: Dependent on source data; no further tests were conducted. Completeness_Report: Because not all communication antennas are required to be registered with the FCC, this data set does not necessarily depict ALL communication features on the landscape. Furthermore, the FCC updates the source database on a daily basis but this shapefile was created for a short-term analysis and contains only data available on 11/6/2003.

Converted the 'degree', 'minute' and 'second' fields for both latitude and longitude into 2 fields (one for latitude, one for longitude) containing decimal degrees using the formula: degrees+(minutes/60)+(seacond/3600). We exported this output table to delimited text (*.txt) format.

There exist dozens of data files all with multiple fieldsdescribing characteristics of the feature data. The point data in this set could be further attributed with data found in the FCC website database. NOTE: For several attirbutes (particularly those pertaining to location or tower height), many values are known to be incorrect and are not included in the range of domain values.
