Abstract: This data set includes refractory, abrasive, and other industrial minerals operations in the United States. The data represent commodities covered by the Minerals Information Team (MIT) of the U.S. Geological Survey. The mineral operations are plants and/or mines considered active in 1997, or in 2001 bentonite and fire clay, and surveyed by the MIT. This file is an update of the 1998 data set.
Purpose: These data are intended for geographic display and analysis at the national level, and for large regional areas. The data should be displayed and analyzed at scales appropriate for 1:2,000,000-scale data. No responsibility is assumed by the U.S. Geological Survey in the use of these data.
Supplemental_Information: Additional minerals operations information can be obtained from the U.S. Geological Survey Minerals Information web page at: <http://minerals.er.usgs.gov/minerals/>

Process_Description: AMIS contains both proprietary and nonproprietary information. For each commodity, the Minerals Information Team (MIT) extracted from AMIS the nonproprietary information useful for this application, and placed this information in a separate data base. The MIT determined latitude and longitude for each mineral operation from at least one of the following sources: Minerals Availability System/Minerals Industry Location System (MAS/MILS) CD-ROM, U.S. Bureau of Mines Special Publication 12-95 <http://www.yahoo.com> Searches performed on company or operation name. <http://www.switchboard.com> Searches performed on company or operation name. <http://www.epa.gov/enviro.html/multisystem_query_java.html> Searches performed on company or operation name. (This site is no longer active.) Whenever possible the locational information was checked for accuracy. The minerals operations were then placed in commodity groupings. The resulting database file was loaded to ArcView and converted to ESRI Shapefile format. The National Atlas staff converted the shapefile to an Arc/INFO coverage and then to NAD83. The result was then converted back to shapefile format.
Process_Description: Bentonite data were deleted from ATLAS-MINOP. BEN-FIRE is a text file containing updated information for bentonite and new information for fire clay. This text file was converted to an Arc/INFO coverage and projected to NAD83. The resulting data was added to ATLAS-MINOP. In addition, the longitude and latitude value for the Josephine County Operation (Plant), Oregon was updated.
Process_Description: In order to geoprocess spatial files for New York State from the National Atlas Data for distribution in CUGIR, the nationwide data files were added to a map document in ArcInfo 8.2. Using the geoprocessing wizard's clip function, the spatial files were clipped to the detailed New York polygon.
