Hydrologic unit codes were added by the USGS and

No overlaps or slivers encountered. Some multi-part
polygons may exist because clipping to the state boundary can
sometimes created separate pieces of the same cataloging unit.

USGS metadata reports -
"All digitized lines fall within 0.025 inches of the source
linework. The source linework had an average thickness of
approximately 0.025 inches. The combined variation of about
0.05 inches at 1:24,000 scale constitutes a potential deviation
of about 100 feet on the ground. The user is reminded that the

A TIC coverage was generated for the State of Indiana and immediate vicinity
with a coordinate TIC at every 7.5 minutes of latitude and longitude. These
TICS corresponded to the corner vertices of the 7.5-minute topographic maps
that included any area in Indiana. The drainage divides on most of the maps
(693 of 710) were digitized by hand on an ALTEK model AC-40 digitizing tablet.
The drainage divides on the remaining 17 maps were scanned on a Scangraphics
model CF1000 scanner.
Following are the procedures used to hand digitize the drainage divides on 693 maps:
Each map was taped to the digitizing tablet. The ARCEDIT module of ESRI ArcInfo was used
to determine the Root Mean Square Error (RMSE) of the 4 map corners as compared to the
4 corresponding TICs in the TIC coverage. All RMSE values for hand-digitized maps were
0.016 (the equivalent of 32 feet on the ground) or less. The RMSE values, along with other
quality-assurance data, are recorded in the arc attribute table, in_hu14.aat. The drainage
divides on the map were digitized in stream mode with a vertex every 0.020 inches
(the equivalent of 40 feet on the ground).
The following ARCEDIT tolerances were set-

The drainage divides on the following 17 topographic maps were scanned-
Bluffton, Gilman, Quincy, Cloverdale, Hazelrigg, Roll, Deerfield, Montpelier, Saline
City, Domestic, Newport, Shannondale, Frankton, Omega, Wallace, Gaston and Petroleum
Following are the procedures used to scan the drainage divides on these 17 maps-
Each map was scanned at 200 dots per inch (true optics out). The Scangraphics Editor
was used to remove extraneous lines from the resulting raster-image file. The ESRI ArcInfo
module ARCSCAN was used to vectorize the raster-image file. All RMSE values for scanned
maps were 0.013 (the equivalent of 26 feet on the ground) or less.
The following Arc Environment Properties were used in ARCSCAN during vectorization-
Copy parallel- default Move parallel- default Rotate angle- default Align distance-
default Vertex distance- 0.556 Node snap tol- Off Arc snap tol- Off Intersect arcs-

Gap- 15.000 Dash- 20.000 Hole- 0.05 Fan angle- 45 2nd angle- 90 Variance- 200
The following general procedures were performed subsequent to digitizing or scanning
in 6-10 maps-
After approximately 6-10 maps were digitized, the coverage was stripped of line overshoots
and undershoots using the CLEAN command with DANGLE=50 and FUZZY_TOLERANCE=1. The newly
digitized lines were then examined along the edges of the map where they should meet
previously digitized lines from an adjoining map. Occasionally the ends of lines on
adjoining maps did not join correctly. The lines on the original maps were examined, and
in most cases, the drainage divides on the original paper maps did not precisely align
across map edges. These lines were corrected on the original maps and the appropriate
portion of the line was re-digitized.
All digitized lines were examined for node dangles, double lines, and sliver polygons.
These errors were corrected and a checkplot of each digitized map was plotted at
1:24,000 scale with a line thickness of 0.025 inches. Checkplots were placed over the
original maps on a light table, and any portion of the digitized linework that did not
overlie the original line was re-digitized. For quality control, 36% of the digitized maps
(256 maps) were later re-plotted and all lines were checked by either a USGS staff
member (other than the individual who originally digitized the map) or an NRCS staff
member. Dates for this quality-assurance activity are recorded in the arc attribute table
in_hu14.aat.
Digitizing efficiency began to decrease after approximately 35-40 maps were digitized
into the coverage. Undue amounts of time were being spent waiting for the image of
digitized lines to be displayed on the computer screen. At this point, a second temporary
TIC coverage was generated in the same manner as the original TIC coverage. Additional
maps were then digitized into this temporary TIC coverage. Periodically, the temporary
coverage was joined with the original coverage using the UNION command. All lines were
then deleted from the temporary coverage. This process was repeated until all requisite
maps were digitized.
Each polygon in the coverage represented a distinct drainage basin and was attributed
with 1) a code indicating whether the polygon represented a contributing or
non-contributing area, and 2) a number based on the discharge point for the basin. These
discharge-point numbers were based on the first column of data in Table 3 in Hoggatt
(1975). An electronic file of the discharge-point numbers was sent to NRCS staff. NRCS
staff used copies of the 1:24,000 scale maps with delineated drainage basins to determine
14-digit HUs according to their guidelines in NRCS National Instruction No. 170-304
(U.S. Department of Agriculture, Natural Resources Conservation Service, 1992, Mapping
and digitizing watershed and subwatershed hydrologic-unit boundaries: National Instruction
no. 170-304, 26 p., accessed May 30, 1997 at URL http://www.nhq.nrcs.usda.gov/hu/ni70304.
html). NRCS staff then updated the electronic file of discharge-point numbers with the
appropriate 14-digit HUC's and returned the file to USGS staff. The USGS staff converted
the file to an INFO table and placed the 14-digit HUC into the item called HUC14_C. The
RELATE function in INFO was used, with the discharge-point number as the relate item,
to attribute each polygon with the 14-digit HUC in an item called HUC_14. This procedure
rendered several contiguous polygons with identical 14-digit HUC's (HUC_14). Lines
dividing contiguous polygons with identical 14-digit HUC's were deleted using the
DISSOLVE command to produce the final polygons in the subject data set.
The STATISTICS function in ARC was used to calculate the total non- contributing
area for each 14-digit HUC. The RELATE function in INFO was then used to attribute
each polygon in the final data set with the total non-contributing area, calculated
in acres. Manual adjustments were made where individual 14-digit HU's were represented
by two or more non-contiguous polygons.
To ensure that each 14-digit HU had the correct boundaries and the correct 14-digit HUC,
checkplots of each map were plotted at 1:24,000 scale with each HU labeled with its HUC.
These checkplots were then sent to NRCS. Any errors were noted and corrected, and new
checkplots were generated and re-checked until every map was correct. Quality-assurance
data for this activity is included in the arc-attribute table (AAT) of the final data set.
HU names, provided by the NRCS, were added to the polygon-attribute table (PAT) of in_hu14.
These names are based on the primary waterway within each HU.
The arcs were assigned a 2-digit attribute, called HU_DIV, indicating the boundary type
represented: 6 = Accounting Unit, 8 = Cataloging Unit, 11 = Watershed, 14 = Subwatershed,
or the Indiana state line. Note that arcs representing the state line have a hu_div = 0
and all other arc attributes are blank or 0.
Three colleague reviews of the final data set of 14-digit hydrologic units, the metadata
and the Fact Sheet were performed in July 1999, two reviews by USGS staff and one review
by a staff member of one of the cooperating agencies, the Indiana Department of Environmental
Management.withheld19960201 - 19990801withheldKrysten M. Debroka and David A. Cohen; Robert E. Dunn and Bruce J. NielsonUS Geological Survey; Natural Resources Conservation Servicemailing and physical address

from ESRI ArcInfo coverage to Shapefile. A dissolve operation was
performed on the HUC_08 field using geoprocessing which merged
all subwatersheds into the larger cataloging unit polygon. Area and
perimeter fields were recalculated by software, but the hu_area
and non-contrib fields were attributed by adding the values of
those fields from the 14HU data. The number subwatersheds merged
