Causey, J.D. Frank, D.G. 2006 1 vector digital data U.S. Geological Survey Data Series DS-228 U.S. Geological Survey http://pubs.usgs.gov/ds/2006/228/ 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, 2004 (from a May 26, 2005 data extraction) for the period from 1976 to 2004 in Arizona, Arkansas, California, Colorado, Florida, Idaho, Montana, Nebraska, New Mexico, Nevada, North Dakota, Oregon, South Dakota, Utah, Washington, and Wyoming. 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 May 26, 2005, since the database is dynamic and new information may have been added after that date, or older information corrected. Data for the individual states are provided in separate files: > Shapefile State >----------------------- > az_pls_04 Arizona > ar_pls_04 Arkansas > ca_pls_04 California > co_pls_04 Colorado > fl_pls_04 Florida > id_pls_04 Idaho > mt_pls_04 Montana > ne_pls_04 Nebraska > nm_pls_04 New Mexico > nv_pls_04 Nevada > or_pls_04 Oregon > sd_pls_04 South Dakota > ut_pls_04 Utah > wa_pls_04 Washington > wy_pls_04 Wyoming 1976 2004 ground condition Complete Annually -125 -80 49 31 None Mining claim Public Land Survey Meridian Township Range Section ISO 19115 Topic Categories geoscientificInformation None Arizona Arkansas California Colorado Florida Idaho Montana Nebraska Nevada New Mexico Oregon South Dakota Utah Washington Wyoming United States None These spatial databases are not meant to be used or displayed at any scale larger than 1:100,000 (for example, 1:24,000). Any hardcopies utilizing these datasets shall clearly indicate their source. If the user has modified the data in any way, they are obligated to describe the types of modifications they have performed on the hardcopy map. User specifically agrees not to misrepresent these data sets, nor imply that changes they made were approved by the U.S. Geological Survey. J. D.

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, NAD27 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. 2005 J. D. Causey U.S. Geological Survey Geologist mailing and physical address
