Description:
Abstract: The locations of Public Land Survey System (PLSS) corners, as represented in geographic coordinate pairs, were derived from a variety of source documents, which include official U.S. General Land Office and BLM survey plats and notes. The attributes assigned to GCDB polygons were taken from the BLM's Legal Land Description data set, contained within the Legacy Rehost for the year 2000, automated records system. At times it is necessary to stack attributes for historic reasons, or for status issues such as split estate. This creates an appearance of overlap. If there is a perceived overlap, the user should consult the source documents. The coordinate data was produced by using control stations of known location, with varying degrees of accuracy, from various sources that include; U.S. Geological Survey (USGS) 1/24,000 series quadrangles, National Geodetic Survey (NGS) first and second order triangulation stations, and Global Positioning System data, which is then adjusted in concert with official survey data for any given geographic area. The GCDB data is a useful representation of the geometry and topology of parcels contained within the PLSS, but its application is intended for mapping purposes only. The GCDB data is not a substitute for a legal land survey.
Purpose: The GCDB was created to provide the BLM and its Public with a set of geographic foundation data that would most accurately portray the locations of PLSS corners. GCDB is based on the BLM and Forest Service survey records and known geographic positions of control stations within the PLSS network. This data will provide the framework upon which the BLM will assemble boundary information for its initial Geographic Information System, and will be instrumental in determining where maintenance and upgrade to the PLSS is necessary.

Attribute_Accuracy:
Attribute_Accuracy_Report:
100% of the data was checked for attribute accuracy by the GCDB personnel
in the BLM State Office.
Logical_Consistency_Report:
Data set is topologically structured polygon data with nodes at all
intersections. All polygons are attributed.
Completeness_Report:
All GCDB spatial outputs are visually inspected for completeness to ensure
that all survey data for a given geographic area is included in the data
set.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
Accuracy of the individual points contained within the GCDB were
adjusted using a least squares analysis, which examines the geometry of
PLSS parcels in relation to the coordinate values of known locations for
control points within the PLSS grid. Each individual point carries a
reliability factor indicating the absolute error of each node.

Process_Step:
Process_Description:
Survey data abstracted from survey plats, and control stations extracted
from control data base, are manually entered into the Coordinate
Geometry (COGO) software PCCS or GMM. A succession of compass rule
adjustments is performed on the survey data to adjust them to the
control points, followed by an averaging of over-computed points in PCCS
or a parametric least squares adjustment in GMM. The resulting
coordinates are accompanied by indications of positional accuracy
estimates for three processes: PCCS - The average and maximum misclosure
in the township. GMM - X/Y abscissa of a true error ellipse. Alternate
Source - Not measureable. Set to values above 9990 to indicate
mathematically qualitative uncertainty.

Process_Description:
If topological errors exist editing of arc, node and attribute data is
performed using GIS software. Final edits are captured in the input
files and processes are repeated until all errors are corrected and
successful GIS coverage is created.
