Causey, J.D. 2006 mt_pls_04 - a shapefile in "Mining Claim Activity on Federal Land in the Contiguous United States, 1976 through 2004" 1 vector digital data Digital Series DS-228 Menlo Park, CA U.S. Geological Survey http://pubs.usgs.gov/ds/2006/228 mt_pls_04Frank, D.G. The mt_pls_04 spatial data set (shapefile) contains Public Land Survey section polygons that had mining claims on December 31, 2004 as recorded in the U.S. Bureau of Land Management's LR2000 database May 26, 2005 for the period from 1976 to 2004. This spatial database was designed to be used with the U.S Bureau of Land Management LR2000 database. It contains a field, MTRS, which allows linking information in the LR2000 case_tbl and case_land tables. However, it is only valid for data downloaded from the LR2000 database May 25, 2005, since the database is dynamic and new information may have been added after that date, or older information corrected. en 20050526 Date that BLM extracted mine claim data from their LR2000 database to provide to U.S. Geological Survey Complete Annually -116.048344 -104.039646 49.000015 44.420780 -116.048344-104.03964644.42078049.000015 None Mining claim Public Land Survey Meridian Township Range Section MontanaNone None This spatial database is not meant to be used or displayed at any scale larger than 1:100,000 (for example, 1:24,000).

These sections were attributed with an appropriate MTRS code or with the meridian code plus the word 'undetermined' (for example '08 undetermined'). In addition, river polygons within or cutting sections were eliminated and the section boundaries completed. The tolerances for the coverage was set to 0.0000000001. The 'clean' and 'build' commands were used to rebuild topology. Paul Hyndman, retired U.S. Geological Survey Geologist mailing and physical address ArcInfoUnknown The coverage was compared with the Idaho digital PLSS at this step to create a common boundary between the states. The individual boundary segments were visually inspected to identify the one that appeared to be better in line quality (smooth vs. jagged). Section lines were extended as necessary to intersect the chosen border segment. Generally the Idaho segments were better than the Montana segments. The coverage was cleaned and built. Paul Hyndman, retired U.S. Geological Survey Geologist ArcInfoUnknown A check was run to identify the number and location of any sections with duplicate names. Several sections were identified; some of the errors may have existed in the original Montana coverage. The duplicates were checked and corrected. Several sections contained two or three polygons because the irregular state border cuts through them.20040709Paul Hyndman, retiredU.S. Geological SurveyGeologistArcInfoUnknownJ.

SpokaneWA99201-1087USA509.368.3116509.368.3199dcausey@usgs.gov8 AM - 4 PM PSTA field, MTRS, was added to the PLS database 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, NAD27 datum. The spatial database was 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.ArcGIS 9.02005J. Douglas CauseyU.S. Geological SurveyGeologistmailing and physical address
