Description
Abstract: This data set is a set of two flat files of fielded data derived from nonconfidential portions of the Minerals Availability System/Minerals Industry Location System (MAS/MILS). One file contains merged information from the Minerals Availability System data base, which lists known mining perations, mineral deposits/occurrences and processing plants, and the Minerals Industry Location System, which identifies more than 221,000 mineral locations and processing plants. The MAS Data Base is a working file of the U.S. Bureau of Mines. Quality of the information can range from preliminary, unconfirmed data to validated assessments. The second file contains bibliographic references for the individual properties contained in the two data bases, indexed on the unique sequence number for each property.
This CD-ROM uses GSSEARCH software, developed by the U.S. Geological Survey, to query and display the data. The initial MAS and MILS computer systems, beginning in the early 1970's, were designed for the sequential storage of coded data on magnetic tap files. The system was downloaded in 1989 to an Oracle data base system which allowed for relational data base structuring of separate data tables.
The original Oracle data base, from which this CD-ROM was derived, is accessible to the public through Telnet.
Purpose: The Minerals Availability System (MAS) is an activity of the Bureau of Mines that systematically measures and classifies identified domestic and foreign mineral resources according to their respective extraction technologies, economics, and availability. The MAS program provides a procedure for continuous monitoring of the present and potential availability of minerals to the United States within the context of many parameters that can impinge upon this availability. Examples of such technical parameters are methods and costs of: mining, beneficiation, smelting, refining, transportation, infrastructure, labor, and capital investment.

Security Classification: Unclassified
Native Data Set Environment: Data set included on CD-ROM includes D:\MASMILS\MASMILS.GBG, where D: is the designated CD-ROM drive, and D:\BIBTAB\BIBTAB.GBG. MASMILS.GBG (size=84 megabytes) is nonproprietary fielded data on the location and legal and physical attributes of the properties of record. BIBTAB.GBG (size= 30 megabytes) is the table of bibliographic references for the properties of record. GBG files are flat data base files created by GSBUILD ver. 4.7, part of a family of nonproprietary software developed by the U.S. Geological Survey for rapid access and retrieval from large data bases. GSSEARCH ver. 5.0 Beta is a complimentary software product to GSBUILD that accesses, queries, and displays the data base.
Data Quality Information
Attribute Accuracy
Attribute Accuracy Report: Attribute accuracy is tested by manual comparison of the source with hard copy plots and/or Geographic Positioning System readouts obtained during field verification visits. Point of Reference, Precision of Point, Elevation Precision and Datum of Elevation are individual fields included in the data base to describe the accuracy of information for individual records. The geographic attributes (latitude, longitude, and elevation) and the accuracy fields mentioned above are documented more extensively in the Data Dictionary included as a document file on the CD-ROM.
Positional Accuracy
Horizontal Accuracy Report: Latitude and Longitude accuracy defined by the Precision of Point data field for each record, and gives the maximum deviation from the exact Point of Reference in meters (e.g., 10, 500, 5000). Precision of Point is required if Point of Reference is entered. An entry of 99,999 indicates that the precision is over 10,000 meters. ZON, HEM, NOR and EAS fields in the database represent the Zone, Hemisphere, Northing, and Easting attributes, respectively, of the Universal Transverse Mercator (UTM) grid coordinate system for the mineral property of record.
Vertical Accuracy Report: Point of Reference, or the physical determination point, elevation precision is defined for each record by the ELP, elevation precision, and DAT, or datum, fields. ELP gives the precision of the measurement in meters. An entry of 9999 indicates that the precision is over 500 meters. Datum of elevation provides for elevations to be expressed above or below either sea level or a local datum.

Other Notes: This example makes use of "blanket" statements that describe all the activities that might have happened to the data set. This approachwas needed because the original data set was developed over a time period in excess of 20 years, and the actual processes applied to this data set are not known.
