Description:
Abstract:
PLSSPOINT: PLSS Point data created by the Bureau of Land Management for the states of Oregon and Washington. 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 (http://www.nationalcad.org/). These are the corners of the PLSS. This feature class contains summary information about the coordinate location and reliability of corner coordinate information. alternate names or aliases for corners are also inlcuded in this feature class.
Purpose:
This data provides the essential observed coordinate information for plss corners. This is not the complete data set for corners. These are the most current coordinates and a summary of information about the accuracy and quality of the coordinate values. Contact the identified data steward for more information.

This data is for GIS and mapping purposes and is not intended to support or replace land survey data or the information provided by land survey. These data are provided by Bureau of Land Management (BLM) "as is" and may contain errors or omissions. The User assumes the entire risk associated with its use of these data and bears all responsibility in determining whether these data are fit for the User's intended use. The information contained in these data is dynamic and may change over time. The data are not better than the original sources from which they were derived, and both scale and accuracy may vary across the data set. These data may not have the accuracy, resolution, completeness, timeliness, or other characteristics appropriate for applications that potential users of the data may contemplate. The User is encouraged to carefully consider the content of the metadata file associated with these data. These data are neither legal documents nor land surveys, and must not be used as such. Official records may be referenced at most BLM offices. Please report any errors in the data to the BLM office for which it was obtained. The BLM should be cited as the data source in any products derived from these data. Any Users wishing to modify the data should describe the types of modifications they have performed.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
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.
Logical_Consistency_Report:
This feature class data set is topologically structured with nodes being constructed from the PLSS Points and hence points being coincident with nodes at all intersections.
Completeness_Report:
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.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
Accuracy of the individual points contained in the PLSSPoint Feature Class that were determined using GMM software the resulting accuracy is reported with the point in the feature class. An overall statement of reliability may be provided for points that are derived from the least accurate component of the error ellipse(largest value). Accuracy of the individual points that were determined using PCCS software a carries positional reliability factor for the average of the misclosures in the data set and the maximum misclosure in the data set.

Process_Description:
For points with a BLM Cadastral as the data steward this feature class is built geographic coordinate database (GCDB) point files. All PLSS Points are at the nodes of line intersections and have a unique identifier as well as any applicable alias that represents the point identifier in adjoining townships or adjoining features. For points with county or state data stewards the PLSS corners are imported from geodatabase files provided by the data steward.
