PLSSTownship
This feature class is part of the Cadastral National Spatial Data Infrastructure (NSDI) CADNSDI publication data set for rectangular and non-rectangular Public Land Survey System (PLSS) data set. The metadata description in the Cadastral Reference System Feature Data Set more fully describes the entire data set. This feature class contains the Public Land Survey System Townships which are the primary unit of survey for the PLSS, nominally six miles on a side, usually containing 36 sections. PLSS Townships are numbered from base lines and principal meridians.
This feature class provides the polygons for the PLSS Townships. These polygons are built from the PLSS Fully Intersected feature class by dissolving on the PLSSID in the Fully Intersected feature class.

File Geodatabase Feature Class
The BLM GCDB personnel using software tools such as dataprep and native GS tools in ArcGIS checked the data for attribute accuracy by verifying it against land records databases such as legal land description (LLD) and Case Status databases. There may be instances where information in survey records and LLD and Case do not agree or places where records are missing. If there are questions about the attribution of a polygon contact the identified data steward.
The spatial features in this feature class were derived from the PLSSIntersected feature class. The topology rules for this feature class are re-checked after the dissolve process. The polygon edges in this feature class overlay the polygon lines in the PLSSIntersected feature class.
This feature class represents all available geographic coordinate database (GCDB) at the time of publication. Every attempt was made to complete the rectangular Public Land Survey System(PLSS) to at least the First Division (section) level and to capture the outside boundary of non-rectangular PLSS features. Gaps or holes in the data that are know areas of conflict are presented in the ConflictedAreas feature class. If there are other gaps it is where data has not been automated, was not available from the data steward or was not of sufficient quality to be included.
The polygon lines are built from the PLSS Points. The PLSS points should be at the nodes of the lines. The horizontal accuracy of the polygon lines is derived from the accuracy of the points at the nodes
This feature class is built from the PLSSIntersected feature through a series of SQL selects, dissolves and geoprocessing. The selection uses only the current PLS data so any polygon labeled with a survey note of R (replaced) will not be used in building derived feature classes. Polygons are combined based on the attributes and rules of combination.
