  Description:
    Abstract:
      This dataset contains latitudes, longitudes, and other
      descriptive data for aggregate producers in New Mexico that are
      believed to have been active during the period 1997-1999. The data
      in this compilation were derived from U.S. Geological Survey files,
      U.S. Bureau of Land Management files, contact with producers, and
      reports from the New Mexico Bureau of Mines and Mineral Resources,
      the New Mexico Bureau of Mine Inspection, and the New Mexico Mining
      and Mineral Division. This dataset includes 2 tables: Table 1 contains
      crushed stone operations and table 2 contains sand and gravel operations.
    Purpose:
      This dataset was developed as part of a larger effort by the
      U.S. Geological Survey to provide plottable locations of
      aggregate producers for National Atlas and for aggregate
      research.
    Supplemental_Information:
      This dataset consists of one Excel 97 spreadsheet file
      (NMsandg2.xls) which contains information about Sand  Gravel
      operations in New Mexico and one Excel 97 spreadsheet file
      NMcstn1.xls) which contains infomation about Crushed Stone
      operations in New Mexico.  The files are also included in DIF
      format under the same filenames, but with the .DIF extension.
  Time_Period_of_Content:
    Currentness_Reference:
      These data are for active and intermittent aggregate producers
      during the period from June 1997 to June 1999.

    This digital database is not meant to be used or displayed at any scale
    larger than 1:24,000.  Some data points are only known within +/- 1 mile.
    The user may need to contact the New Mexico Bureau of Mines and Mineral
    Resources or the New Mexico Bureau of Mine Inspection, or the Bureau of
    Land Management for updates and additional information on current producers.

  Data_Set_Credit:
    Data were compiled by Greta J. Orris and Paul Oland on aggregate producers
    from U.S. Geological Survey files, U.S. Bureau of Land Management files,
    company data, and reports from the New Mexico Bureau of Mines and Mineral
    Resources, the New Mexico Bureau of Mine Inspection, and the New Mexico
    Mining and Mineral Division. Compilation included verification of the data
    to the extent possible, removal of duplicate records and conversion of
    township, range, and section locations and other location descriptions to
    latitude and longitude. The latitudes and longitudes were largely determined
    using 1:24,000 scale topographic maps and the accuracy of these locations
    vary with the detail of the original information. Less than 30 locations
    were determined from site visits using a GPS instrument with a resolution
    of 15 m.
  Native_Data_Set_Environment: MS Excel 97 or later, or a DIF-compatible program

    Attribute_Accuracy_Report:
      The accuracy of source data attributes was based on agreement between
      sources and not verified on the ground.

      Horizontal_Positional_Accuracy_Report:
        The horizontal positional accuracy of the digital data was checked 
        against the original file data. The latitudes and longitudes were 
        largely determined using 1:24,000 scale USGS topographic maps using 
        township, range, and section data or other location descriptions from 
        the original dataset. The accuracy of these locations vary with the 
        detail of the original information. Less than 30 locations were 
        determined from site visits using a GPS instrument with a resolution 
        of 15 m.
