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.
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.
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. Company Name - Operating company's name
2. County - County of operation
3. Site Name/Other Operator - Name of site or name of other known operator
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
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
The details of attributes included in this dataset were compiled by Greta
J. Orris and Paul Oland.
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.
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.
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.
The U.S. Geological Survey (USGS) provides these geographic data "as is."
The USGS makes no guarantee or warranty concerning the accuracy of
information contained in the geographic data. The USGS further makes no
warranties, either expressed or implied as to any other matter whatsoever,
including, without limitation, the condition of the product, or its fitness
for any particular purpose. The burden for determining fitness for use lies
entirely with the user. Although these data have been processed successfully
on computers at the USGS, no warranty, expressed or implied, is made by the
USGS regarding the use of these data on any other system, nor does the fact

In no event shall the USGS have any liability whatsoever for payment of any
