What does this data set describe?

Title: Dataset of Aggregate Producers in New Mexico
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.
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.

    4. MSHA No. - Mining Safety & Health Administration ID number
    5. Latitude - Latitude in decimal degrees
    6. Longitude - Longutide in decimal degrees
    7. Section - Section
    8. TNSH - Township
    9. RNG - Range
    10. Quadrangle - USGS 7.5-minute topographic quadrangle containing location
    11. Commodity - Commodity produced (crushed stone spreadsheet only)
    12. Comments - Additional comments include section fractions, location accuracy, description of the location, and other data.
    13. Mineral Estate - Ownership of mineral rights

Who produced the data set?

  1. Who are the originators of the data set? (may include formal authors, digital compilers, and editors)
    • Greta J. Orris
  2. Who also contributed to the data set?
    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.

Why was the data set created?

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.

  3. What similar or related data should the user be aware of?

How reliable are the data; what problems remain in the data set?

  1. How well have the observations been checked?
    The accuracy of source data attributes was based on agreement between sources and not verified on the ground.
  2. How accurate are the geographic locations?
    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.
  3. How accurate are the heights or depths?
  4. Where are the gaps in the data? What is missing?
  5. How consistent are the relationships among the observations, including topology?
    Point data is given in latitude/longitude decimal degrees.

How can someone get a copy of the data set?

Are there legal restrictions on access or use of the data?
