Description: Township, range, and section boundaries from the public
land survey system.
Abstract:
This data set contains township, range, and section boundaries from
the public land survey system for Oklahoma. This data set was
created by appending and editing U.S. Geological Survey Digital
Line Graph data sets based on 1:100,000-scale topographic
quadrangles.
Introduction:
This data set contains township, range, and section boundaries from
the public land survey system for Oklahoma. This data set was
created by appending and editing U.S. Geological Survey (USGS)
Digital Line Graph (DLG) data sets (1994) based on 1:100,000-scale
topographic quadrangles.
Purpose:
This data set is intended for displaying the public land survey
system at scales of 1:100,000 or smaller.
Supplemental_Information:
Procedures_Used: The DLG data sets were acquired on 9-track tape.
These data are now available for downloading by anonymous ftp from,
ftp://edcftp.cr.usgs.gov/pub/data/DLG/100K/. The DLG data sets are
organized in alphabetical order by quadrangle name in the
subdirectory public lands.
The USGS 1:100,000-scale DLG files (1994) were converted to
ARC/INFO format and joined to create a single statewide ARC/INFO
data set. All standard USGS DLG major and minor codes were
simplified to the attribute scheme describe in the
Entity_and_Attribute_Overview section of this documentation
file. The data set was processed with the ARC/INFO command CLEAN
(ESRI, 1995) with a dangle length of 0 meters and a fuzzy tolerance
of 50 meters. Extra label points were deleted in ARCEDIT. The
ARC/INFO command ELIMINATE (ESRI, 1995) was used to remove tiny
sliver polygons formed between quadrangle edges. The ARC/INFO
command DISSOLVE (ESRI, 1995) was used to eliminate quadrangle
boundaries.
Many mislabeled polygons were corrected, using ARCPLOT (ESRI, 1995)
to display the data set and correct polygon attributes. Sections
were displayed row-by-row (for example, sections numbers 1-6 from
all townships were displayed at once) and column-by-column to help
identify mislabeled polygons. When necessary, the USGS
1:100,000-scale and 1:24,000-scale quadrangle maps were used to
determine the correct polygon attributes.
The major and minor pairs were created and the data set was
documented using ARC/INFO DOCUMENT.AML (ESRI, 1995). The ARC/INFO
command CLIP (ESRI, 1995) was used to divide the statewide data set
into separate data sets by county. ARC/INFO export files and
DLG-format files were generated for each county data set.

Reviews_Applied_to_Data:
The Digital Atlas of Oklahoma was reviewed by 13 technical
reviewers. Because of the large volume of data (nearly 1.3 million
points, lines or polygons divided into 861 separate data sets) the
reviewers could not thoroughly check the accuracy of all geographic
features in the data sets. Reviewers were asked to check the
topological consistency, tolerances, attribute frequencies and
statistics, projection, and geographic extent. The reviewers were
asked to check the metadata and other documentation files for
completeness and accuracy. Users should exercise caution and
judgment in applying these data, and be aware that errors may be
present in any or all of the digital map data layers.

Overview_Description:
Entity_and_Attribute_Overview:
Each polygon has six attributes. The first attribute, MERIDIAN,
contains the number 11 for surveys based on the Cimarron Meridian
(Oklahoma panhandle), or the number 17 for surveys based on the
Indian Meridian, covering the remainder of Oklahoma. The second
attribute, TOWNSHIP, contains the township number. The third
attribute, NS, contains the letter N or S to show whether the
township is north or south of the baseline. The fourth attribute,
RANGE, contains the range number. The fifth attribute, EW, contains
the letter E or W to show if the range is east or west of the
meridian. The sixth attribute, SECTION, contains the section
number. MERIDIAN, TOWNSHIP, RANGE, and SECTION values of 99 are
used for void areas not included in the public land survey system.
The attribute, MERIDIAN, in the DLG version is stored in the
first major code (MAJOR1) and TOWNSHIP is stored in the first minor
code (MINOR1). NS is stored in the second major code (MAJOR2) as
integers, where N = 1 and S = 2. RANGE is stored in the second minor
code (MINOR2). EW is stored in the third major code (MAJOR3) as
integers, where E = 1 and W = 2. SECTION is stored in the third
minor code (MINOR3).
