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 polygons that had a record in the LR2000 database were selected. This selection was saved as the present shapefile.
