Title: BLM REA NOS 2012 Alaska Resource Data File HardRock
Online Linkage: http://ardf.wr.usgs.gov/
Description:
Abstract: Database of descriptions of mines, prospects, and mineral occurrences in Alaska.
Purpose: Alaska Resource Data File (ARDF) contains a database of descriptions of placers, mines, prospects, and mineral occurences.
Supplemental Information: The Alaska Resource Data File is hosted by the U.S. Geological Survey but depends on many agencies to keep information up to date and accurate. The accuracy and concurrency of information varies between records.

Data Quality Information:
Attribute Value Accuracy Information:
Attribute Accuracy Report: Attribute information accuracy varies between records. There is no standard approach to keeping records up to date.
Logical Consistency Report: A site is a single geographic location, point or area, which may have had multiple site names. For historical perspective, all proper names are listed.
Completeness Report: ARDF is mainly concerned with the metallic commodities. Common industrial minerals such as sand and gravel, crushed stone, and limestone are not included, nor are energy minerals such as peat, coal, and oil and gas. Uranium and thorium, and rare earth elements are included, as well as high unit-value industrial minerals as barite, jade, graphite, and gypsum.
Positional Accuracy:
Horizontal Positional Accuracy:
Horizontal Positional Accuracy Report: The location of a site is given in decimal degrees. Some sites are areas rather than points and the geographic coordinates are the approximate center of the area. The precision of the latitude and longitude is reflected in the number of decimal places given. A narrative description of the location and the precision of the location is given in the text field 'Location description and accuracy'.
Positional Accuracy:
Vertical Positional Accuracy:
Vertical Positional Accuracy Report: This dataset does not include a vertical component.
