Description:
Abstract:
Database of descriptions of mines, prospects, and mineral occurrences in Alaska.
Purpose:
The Alaska Resource Data File (ARDF) is a subset of the National Mineral Resource Data System (MRDS) that has been specifically re-formatted and re-designed to better meet the needs of the local user community.

Data_Quality_Information:
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'.
Lineage:
Process_Step:
Process_Description:
The original ARDF records came from the national database MRDS. The ARDF records are being updated from information of government, industry, and literature sources. The updated ARDF records are fed back to the national MRDS database. Downloaded Filemaker Pro database file (ARDFcomp.fp5) on 05/04/2005 from ARDF website: http://ardf.wr.usgs.gov/digital.html. Imported ARDFcomp.fp5 into Filemaker Pro 6.0 and exported all records as a DBF file. Left out the following 5 fields because field length record exceeded 255 characters: Location, Geologic Description, Workings/exploration, Additional Comments, References. Imported DBF file into ArcView 3.2 and created shapefile: ardf05042005b.shp

Process_Description:
Downloaded ardfcomp.CSV from http://ardf.wr.usgs.gov/ Removed a few duplicate rows in this file. Converted for use in Mineral Resources On-Line Spatial Data web site. Modified nonprintable characters 0x82 to eacute (0xe9), removed nonprintable characters 0x0B, removed excess spaces and tab characters.
