Why was the data set created?

To provide mineral location information in a spatial data form for use in spatial analyses.

How was the data set created?

  1. From what previous works were the data drawn?
    MAS/MILS (source 1 of 1)
    U.S. Bureau of Mines, Unpublished, MAS/MILS database.

    Type_of_Source_Media: digital
    Source_Contribution: All data in the coverage came from this source
  2. How were the data generated, processed, and modified?
    Date: 23-Jun-1998 (process 1 of 2)
    Data were extracted from the MAS/MILS database. Points were generated and additonal field of information were added to the feature attribute table using joinitem. Data from the commodity table was put in antoher table. A relation was extwblished between the com table and the fearure attribute table.
