  Description:
    Abstract:
      The id_pls_03 spatial data set (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 January 15, 2004 for the period from 1976 to 2003.
    Purpose:
      This spatial database was designed to be used with the U.S Bureau of Land Management LR2000 database. It contains a field, MTRS, that allows linking information in the LR2000 case_tbl and case_land tables. However, it is only valid for data downloaded from the LR2000 database January 15, 2004, since the database is dynamic and new information may have been added after that date, or older information corrected.

    Process_Step:
      Process_Description:
        The unsurveyed areas (lakes and unsurveyed blocks) within the coverage were filled by protracting section lines and creating new sections. 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.

      Process_Description:
        The coverage was compared with the Montana 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.

      Process_Description:
        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 Idaho coverage. The duplicates were checked and corrected. Several sections contained two or three polygons because the irregular state border cuts through them.

      Process_Description:
        A 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
