Metadata from the RGIS Metadata Repository
Identification Information
- Title Cadastral PLSS Standardized Data - PLSSIntersected (Dalhart) - Version 1.1
- Date 2013-04-17
- Date Type Publication
- Cited Responsible Party
-
- Organization Name BLM Cadastral Survey - NM
- Role identify
- Presentation Form vector digital data
- 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 Report
-
- 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.
- Quantitative Attribute Accuracy Assessment
-
- Attribute Accuracy Value
- Attribute Accuracy Explanation
- Horizontal Positional Accuracy Report
-
- 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

- Logical Consistency Report 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.
- 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.

- Process Step
-
- 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 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 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.
