Description:
Abstract:
Selected elements of Nevada records contained in the MRDS
database were taken from "An Arc/Info point coverage of
Mineral Resource Data System (MRDS) Locations in Eleven
Western States, USGS Open-File Report 99-169" and "U.S
Geological Survey Mineral Databases - MRDS and MAS/MILS, by
E.J. McFaul, G.T. Mason Jr., W.B. Ferguson, and B.R. Lipin,
USGS Digital Data Series DDS-52" and converted to shapefile
format and projected to UTM, zone 11, NAD27 coordinates.
This dataset, Nv_mrds, was then exported from shapefile
format to a standard dBaseIII+ format for nongraphic
applications and use in other GIS type systems. Nv_mrds
contains 6,903 records.
Purpose:
To make available USGS MRDS summary digital data on
various mine sites located in Nevada.
Supplemental_Information:
All data manipulations were performed to a standard that
maintained the location accuracy of the initial data, i.e.,
the accuracy of MRDS and MILS data. Therefore the location
of data points is only as good as the accuracy and
completeness of the original digital data supplied by the
U.S. Geological Survey and U.S. Bureau of Mines. In some
cases the location information in these databases is of
very poor resolution but in most cases the data are
sufficiently accurate to convey the needed information for
this project. Furthermore, very few records have available
information for every field in a record.

DATA_QUALITY_INFORMATION
Attribute_Accuracy:
Attribute_Accuracy_Report:
All attributes created during the creation process were
verified by displaying the points in both the database and
the spatial coverage, but no formal tests were performed.
Logical_Consistency_Report:
These data are believed to be logically consistent, though
no tests were performed.
Completeness_Report:
Data file contains those data points available from
identified references at the time of project.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
No set value has been identified for positional accuracy of
each point. All data manipulations were performed to a
standard that maintained the location accuracy of the
initial data, i.e., the accuracy of MRDS and MAS/MILS data.
Therefore the location of data points is only as good as
the accuracy and completeness of the original digital data
supplied by the U.S. Geological Survey and U.S. Bureau of
Mines. In some cases the location information in these
databases is of very poor resolution but in most cases the
data are sufficiently accurate to convey the needed
information for this project. Furthermore, few records have
available information for every field.
