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).
