This dataset contains the locations of mineral and metal operations 
in the United States. 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 1997 and surveyed by the MIT.

FEATURE ATTRIBUTE TABLES CODES AND VALUES:

ITEM             ITEM DESCRIPTION 
SHAPE            Data attribute inherent to the ESRI shapefile format,
                 which defines the data as a point, polyline, or polygon.

SITE_NAME        The name of the facility.
COMPANY_NAME     The name of the company which operates the facility.
                 The mineral(s) and/or metal(s) produced or processed by the
                 facility.

COMMODITY        The mineral(s) and/or metal(s) produced or processed by
                 the facility.

LATITUDE         Angular distance measured on a meridian north or south from the
                 equator.

LONGITUDE        Angular distance between the plane of a meridian east or west 
		 from the plane of the meridian of Greenwich.

PLANT_MIN        Whether the facility is a plant or a mine.
                 M = The facility is a mine
                 P = The facility is a plant
                 M/P = The facility is both a mine and a plant
                 
COUNTY           County Name the facility is located within
DESCRIPT         FGDL added item based on COMMODITY

USER NOTES:

The data can be used to conduct geographic analysis on national and large 
regional scales.  The digital data set of the Minerals Information Team is 
used to create electronic and hard copy maps that depict various mineral 
or metal mine and/or processing locations on a national map.  The data can 
be used to conduct geographic analysis on national and large regional scales.
Additional mineral and metal operations information can be obtained from the 
U.S. Geological Survey Minerals Information Team web page at:

A note concerning data scale:
Scale is an important factor in data usage. Certain scale datasets are not
suitable for some project, analysis, or modelling purposes. Please be sure
you are using the best available data.
1:24000 scale datasets are recommended for projects that are at the county
level. 1:24000 data should NOT be used for high accuracy base mapping such
as property parcel boundaries.
1:100000 scale datasets are recommended for projects that are at the
multi-county or regional level.
1:250000 scale datasets are recommended for projects that are at the
regional or state level or larger.
Vector datasets with no defined scale or accuracy should be considered
suspect. Make sure you are familiar with your data before using it for
projects or analyses. Every effort has been made to supply the user with
data documentation. For additional information, see the References section
and the Data Source Contact section of this documentation. For more
information regarding scale and accuracy, see our web pages at:

FGDL QUALITY ASSURANCE STATUS:

-Projected data to FGDL Albers HPGN (See "Map Projection Parameters" below).
-Clipped to the State of Florida
-DESCRIPT item added based on COMMODITY
-Upcased all character records.

DATA LINEAGE SUMMARY:

GeoPlan downloaded this data in shapefile format from the USGS website
at: http://mrdata.usgs.gov/sddpftp.html. When received, the data was in 
the following projection: Geographic, Datum: NAD 27, Spheroid: Clarke 1866, 
Units: Decimal Degrees. The shapefile was clipped to the State of Florida
boundary, and projected to FGDL Albers HPGN (See "Map Projection Parameters" 
below). All character items in the attribute tablewere upcased and the 
DESCRIPT item was added based on the item COMMODITY.
