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.    Time_Period_Information:      Range_of_Dates/Times:        Beginning_Date: 199706        Ending_Date: 199906  Status:    Maintenance_and_Update_Frequency: No updates are planned.    Progress: Complete  Spatial_Domain:    Bounding_Coordinates:      West_Bounding_Coordinate: -109.50      East_Bounding_Coordinate: -103.00      North_Bounding_Coordinate: 37.0      South_Bounding_Coordinate: 31.33  Keywords:    Theme:      Theme_Keyword_Thesaurus: None      Theme_Keyword: crushed stone      Theme_Keyword: gravel      Theme_Keyword: sand    Place:      Place_Keyword_Thesaurus: None      Place_Keyword: USA      Place_Keyword: New Mexico  Access_Constraints: None.  Use_Constraints:    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.  Point_of_Contact:    Contact_Information:      Contact_Person_Primary:        Contact_Person: 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Data_Quality_Information:  Attribute_Accuracy:    Attribute_Accuracy_Report:      The accuracy of source data attributes was based on agreement between      sources and not verified on the ground.  Logical_Consistency_Report: Point data is given in latitude/longitude decimal degrees.  Positional_Accuracy:    Horizontal_Positional_Accuracy:      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.  Lineage:    Process_Step:      Process_Description:        Data were separated into various fields (categories) within the Excel        spreadsheets.      Process_Date: 2000    Source_Information:      Source_Citation:        Citation_Information:          Originator:            New Mexico Bureau of Mine Inspection            New Mexico Bureau of Mines & Mineral Resources            New Mexico Institute of Mining & Technology          Publication_Date: 1998          Title: Mines, Mills  Quarries in New Mexico, 1998      Type_of_Source_Media: Paper      Source_Time_Period_of_Content:        Time_Period_Information:          Single_Date/Time:            Calendar_Date: 1998        Source_Currentness_Reference: Current - Publication Date      Source_Citation_Abbreviation: NMBMI, NMBMMR, NMIMT      Source_Contribution:        Locations of known sites and additional, previously         unknown information.    Source_Information:      Source_Citation:        Citation_Information:          Originator: U.S. Bureau of Land Management          Publication_Date: 1998          Title: ORCA Dataset      Type_of_Source_Media: Paper      Source_Time_Period_of_Content:        Time_Period_Information:          Single_Date/Time:            Calendar_Date: 1998        Source_Currentness_Reference: Current - Release Date      Source_Citation_Abbreviation: USBLM      Source_Contribution:        Locations of known sites and additional, previously         unknown information.    Source_Information:      Source_Citation:        Citation_Information:          Originator: U.S. Geological Survey Minerals Information Team          Publication_Date: 1998          Title: Working file information      Type_of_Source_Media: Digital file      Source_Time_Period_of_Content:        Time_Period_Information:          Single_Date/Time:            Calendar_Date: 1998        Source_Currentness_Reference: Current - Release date      Source_Citation_Abbreviation: USGS, MIT      Source_Contribution:        Locations of known sites and additional, previously         unknown information.  Completeness_Report: This report is complete.Spatial_Data_Organization_Information:  Direct_Spatial_Reference_Method: Point  Point_and_Vector_Object_Information:    SDTS_Terms_Description:      SDTS_Point_and_Vector_Object_Type: Point      Point_and_Vector_Object_Count: 276Spatial_Reference_Information:  Horizontal_Coordinate_System_Definition:    Geographic:      Latitude_Resolution: 1      Longitude_Resolution: 1      Geographic_Coordinate_Units: Decimal DegreesEntity_and_Attribute_Information:  Overview_Description:    Entity_and_Attribute_Overview:      The dataset consists of two MS Excel 97 files: NMsdg.xls and NMcstn.xls      which are displayed as tables 1 and 2, respectively, in the OFR text.      Definitions of the fields are:      1.
