Abstract:
The Public Land spatial data sets (shapefile) contains Public Land Survey section polygons that had mining claims recorded in the U.S. Bureau of Land Management's LR2000 database as of December 31, 2010 (from a March 1, 2011 data extraction) for the period from 1976 to 2010 in Arizona, Arkansas, California, Colorado, Florida, Idaho, Montana, Nebraska, New Mexico, Nevada, North Dakota, Oregon, South Dakota, Utah, Washington, and Wyoming. Alaska was not updated in version 4.
Purpose:
This set of spatial databases was designed to be used with the U.S Bureau of Land Management LR2000 database. Each shapefile contains a field, MTRS, which allows linking information in the LR2000 case_tbl and case_land tables. However, it is only valid for data extracted from the LR2000 database on March 1, 2011, since the database is dynamic and new information may have been added after that date, or older information corrected.
Supplemental_Information:
Shapefile names for the individual states are: ak_pls_07, az_pls_10 (Arizona), ar_pls_10 (Arkansas), ca_pls_10 (California), co_pls_10 (Colorado), fl_pls_10 (Florida), id_pls_10 (Idaho), mt_pls_10 (Montana), ne_pls_10 (Nebraska), nm_pls_10 (New Mexico), nv_pls_10 (Nevada), or_pls_10 (Oregon), sd_pls_10 (South Dakota), ut_pls_10 (Utah), wa_pls_10 (Washington), and wy_pls_10 (Wyoming).

Base spatial databases for report "Mining Claim Activity on Federal Land in the United States", By J. D. Causey
Process_Step:
Process_Description:
A field, MTRS, was added to the PLS databases by concatenating meridian, township, range, and section information into one 18-character string. The string is in the format MM TTTTT RRRRR SSS where MM is a 2-digit number, TTTTT is township, RRRRR is range, and SSS is section for any valid Public Land Survey values. Township and range are 5 characters of the form XXXYZ where X is a numeric, Y is 0 or 2, and Z is N or S for township and E or W for range. A Y value of 2 means that the township or range are fractional township or ranges, otherwise the value is 0. Section is a 3-digit numeric. Then all fields except MTRS were deleted.

All datasets were then projected to Geographic coordinate system, NAD83 datum.

The spatial databases were attached to a list of unique MTRS values from the LR2000 database and all polygons that had a record in the LR2000 database were selected. This selection was saved as the present shapefile.
