Title: BLM OR WA Cadastral PLSS Corners Point
Originators: BLM Cadastral Survey - <ST>
Publication date: unknown
Data type: vector digital data
Description
A characterization of the data, including its intended use and limitations.
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.

Data Quality and Accuracy Information
General
Information about the fidelity of relationships, data quality and accuracy tests, omissions, selection criteria, generalization, and definitions used to derive the data.
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.
Attribute Accuracy
Accuracy of the identification of data entities, features and assignment of attribute values.
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.
Positional Accuracy
Accuracy of the positional aspects of the data.
Horizontal 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.
Data Source and Process Information
Process Steps
Information about events, parameters, tolerances and techniques applied to construct or derive the data.
Process step information
Process Step 1
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.

Metadata Standards
Description of the metadata standard used to document the data and reference to any additional extended profiles to the standard used by the metadata producer.
Standard name: FGDC Content Standard for Digital Geospatial Metadata
Standard version: FGDC-STD-001-1998
Time convention: local time
FGDC Plus Metadata Stylesheet
Stylesheet: FGDC Plus Stylesheet
File name: FGDC Plus.xsl
Version: 2.0
Description: This metadata is displayed using the FGDC Plus Stylesheet, which is an XSL template that can be used with ArcGIS software to display metadata. It displays metadata elements defined in the Content Standard for Digital Geospatial Metadata (CSDGM) - aka FGDC Standard, the ESRI Profile of CSDGM, the Biological Data Profile of CSDGM, and the Shoreline Data Profile of CSDGM. CSDGM is the US Federal Metadata standard. The Federal Geographic Data Committee originally adopted the CSDGM in 1994 and revised it in 1998. According to Executive Order 12096 all Federal agencies are ordered to use this standard to document geospatial data created as of January, 1995. The standard is often referred to as the FGDC Metadata Standard and has been implemented beyond the federal level with State and local governments adopting the metadata standard as well. The Biological Data Profile broadens the application of the CSDGM so that it is more easily applied to biological data that are not explicitly geographic (laboratory results, field notes, specimen collections, research reports) but can be associated with a geographic location. Includes taxonomical vocabulary. The Shoreline Data Profile addresses variability in the definition and mapping of shorelines by providing a standardized set of terms and data elements required to support metadata for shoreline and coastal data sets. The FGDC Plus Stylesheet includes the Dublin Core Metadata Element Set. It supports W3C DOM compatible browsers such as IE7, IE6, Netscape 7, and Mozilla Firefox. It is in the public domain and may be freely used, modified, and redistributed. It is provided "AS-IS" without warranty or technical support.

Click on a section name (e.g. Description) to open and close section content. Within a section, click on a item name (Status, Key Words, etc.) to open and close individual content items. By default, the Citation information within the Description section is always open for display.
