Abstract: This data set includes crushed stone operations in the United States. These data were obtained from information reported voluntarily to the USGS by the aggregate producing companies. The data represent commodities covered by the Minerals Information Team (MIT) of the U.S. Geological Survey, and the operations are those considered active in 1998 with production greater than 30,000 tons and surveyed by the MIT.
Purpose: These data are intended for the 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.usgs.gov/minerals/>.

Title: Automated Minerals Information System (AMIS)
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: Delorme Street Atlas software (Searches performed on addresses.) <http://www.yahoo.com/> (Searches performed on company or operation name.) <http://www.superpages.com/> (Searches performed on company or mine id.) <http://www.msha.gov/> (Searches performed on company or operation name.) Whenever possible the locational information was checked for accuracy. The resulting database file was loaded to ArcView and converted to ESRI Shapefile format. The National Atlas staff converted the shape file to an Arc/INFO coverage and then to NAD83. The National Atlas staff also added the State-fips code and converted the full State name to the two-character code. Several coordinate values were corrected so that point locations fell in the correct State. The result was then converted back to shapefile format.
