Description:
Abstract:
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. The fully intersected data is the atomic level of the PLSS that is similar to the Esri coverage or the smallest pieces used to build the PLSS. Polygons may overlap in this feature class. This feature class will also contain retired or replaced areas of the PLSS.
Purpose:
The fully intersected polygons are used for conversion and for maintenance. The contain the atomic and fully attributed components of the other PLSS features. This is the feature class used to derive other feature classes in this data set. This feature class also contains retired or replaced features.

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.
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:
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

Process_Description:
BLM Cadastral Survey using the computational programs of either GMM or PCCS has generated the data where BLM Cadastral is the identified data steward. For both programs the first step is to compile survey input data from the best and most current survey records. Control points are identified, evaluated and entered into a control database With GMM the survey data, measurements abstracted from survey plats, and control stations extracted from the control database are manually entered with weighting factors into GMM software. Compass rule and least squares adjustments are performed using weighting factors assigned to both control stations and survey line data, based on survey methodologies and vintage of survey. With GMM, section subdivision is performed to achieve land unit detail to at least the forty acre (1/16th ) level. Instructions for calculating non-regular and minor subdivisions are persistently stored during collection and rerun after every new adjustment in order to achieve the detail necessary to delineate all lines required for depicting federal rights, interests, restrictions, and encumbrances. Coincident lines and lines identified as non-boundary lines are removed from the data set used for final land unit constructions. Line intersections are computed and given unique identifiers and land units are constructed. GMM lists all coordinates produced by the compass rule and least squares adjustments and subdivision, with connectivity codes between points and compiles them into a single file for development of Geographic Information Systems (GIS) output. With PCCS the survey data, measurements abstracted from survey plats, and control stations extracted from the control database are manually entered into the PCCS processing software. A succession of compass rule adjustments is performed on the lines to adjust them to the control points, followed by a least squares analysis. The resulting coordinates are accompanied by indications of positional reliability; the average of misclosures in the data set and the maximum misclosure in the data set. PCCS lists all coordinates produced by the compass rule and least squares adjustments with connectivity codes between points and compiles them into a single file for development of Geographic Information Systems (GIS) output. With PCCS, section subdivision is performed to achieve land unit detail to at least the forty acre (1/16th) level.
Process_Step:
Process_Description:
GCDB data conversion software (also called data prep) verifies correctness of GCDB file formats and content based on the polygon coding and the rules associated with those codes. Verified coordinate, line and label files are converted to GIS coverages using the topology check application. All errors in topology are flagged for editing and correction. If topological errors exist, editing of arc and node data, as well as parcel labels, is performed using either GMM or ArcGIS Interface. Final edits are entered into input files and the process is repeated until all errors are corrected and a successful GIS coverage is created. GIS coverages are edge matched with adjoining township data sets to insure a seamless PLSS data set is created. Topologically correct GIS coverages are modified to use FGDC compliant naming conventions and then loaded into the CADNSDI.
Process_Step:
Process_Description:
The resulting GCDB data sets are imported into a file geodatabase feature class called LADESC and the points are loaded into the PLSSCorners feature class. A series of extract-transfer-load (ETL) routines are run to import the data into the PLSS Intersected feature class. Metadata is loaded and edited.
