  Description:
    Abstract: Cellular phone microwave towers registered with the U.S. Federal Communications Commission. Not all antennas are required to be registered with the FCC, therefore, this data set does not necessarily depict ALL cellular phone communication towers actually present on the landscape.  The source data are updated weekly by the FCC as new permits are issued.  However, this particular 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 towers are mislocated in the source data.

Data_Quality_Information:
  Attribute_Accuracy:
    Attribute_Accuracy_Report: The location of several features have incorrect coordinates.  The true accuracy of the remaining features is unknown and untested.
  Logical_Consistency_Report: Dependent upon the source data.
  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 this source database on a weekly basis but this shapefile was created for a short-term analysis and contains only data available on 11/6/2003.

    Process_Step:
      Process_Description: We imported the 'LO.dat' table into MS Access, then extracted pertinent data into a new table using the 'make-table' query function.  We then 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 into delimited text (*.txt) format.
