Description:
Abstract:
The or_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.

This spatial database is 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.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report: Not stated in source metadata
Logical_Consistency_Report:
All polygons are closed and adjacent polygons do not have identical attributes. Each polygon has one and only one attribute
Completeness_Report:
Each map once digitized was plotted on semi-translucent paper and overlayed with the original on a light-table. Any inconsistencies in linework or attributing was noted on the map and "checked off" as the needed changes were completed. (Lab standards similar to National Mapping Standards were strictly followed. For example, lab standards required that any linework deviating from the original map enough for "white space" to exist between the edit plot and the source map be documented and fixed. Step one was then performed again until no more errors were found.)

Once all digitized maps were joined into one coverage several "dissolve" processes were performed to look for any inconsistencies in attributing. Dissolves were performed on both TOWNSHIP and RANGE. Searches were also made on the coverage for unattributed slivers and for polygons less than 10 acres that might have been errors.

Process_Step:
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.

Projected to Geographic coordinates, 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.
