Title: onemap_prod.SDEADMIN.hunc_poly
Abstract:
The USDA-Natural Resources Conservation Service, Raleigh Office in cooperation with the NC Center for Geographic Information & Analysis, and the NC Dept. of Environment, Health and Natural Resources, Division of Water Quality developed the Hydrologic Units-North Carolina digital data to track resource and conservation activities in the state's river basins and subbasins. Using the 14-digit hyrologic unit code the regional, subregional, accounting, cataloging, NRCS sub-unit, and NRCS reporting unit boundaries id's are recorded. The area attributes allow the user to see hydrologic unit, river basin and subbasin levels of geography.
Supplemental_Information:
Data from the protected and critical watersheds layer for the state was used during the development of the HU boundaries. This coverage supersedes data on past versions, particularly the cama24.hu coverage, which was completed as a preliminary to this statewide version. Some boundaries may have changed between the two versions. There are two additional coverages which were generated from this data, the huncrb-river basins; and huncsb-subbasins files. See the cross references section for details.
The following is an excerpt from the "North Carolina Hydrologic Unit River Basin Study," USDA, Natural Resources Conservation Service, November 1995. Under the sponsorship of the Water Resources Council, a nationally uniform hydrologic unit system was developed in 1974 by the US Geological Survey's Office of Water Data Coordination. This system divides the country into 21 regions, 222 subregions, 352 accounting units, and 2,149 cataloging units, based on surface hydrologic features. A hierarchical code consisting of two digits for each of the above four levels combine to form an eight-digit hydrologic unit. The hydrologic unit system is used to identify any hydrologic area of interest. An eight-digit hydrologic unit generally covers 700 or more square miles. In 1978, the USDA-Natural Resources Conservation Service (NRCS) issued a policy that all resource inventories and surveys were to be coded with and capable of being retrieved by hydrologic unit codes (HUCs). At about the same time, NRCS initiated a national program to further subdivide HUCs into watershed-sized areas (nominally 250,000 acres, or 390 square miles) for use in water resource planning. An extension of three digits was added to the eight-digit HUC to designate sub-watersheds, thus forming elevin-digit HUCs. This 1995 Hydrologic Unit (HU) Study divides the state river basins and subbasins into smaller fourteen-digit hydrologic units that will be useful in targeting project activities, resource inventories, and reporting conservation activities. These fourteen-digit hydrologic units of approximately 4,000 acres (6 sqare miles) to 50,000 acres (78 square miles) are small enough in size to be useful as a planning and reporting tool for the USDA-Natural Resources Conservation Service (NRCS) and other government and state agencies. This 1995 fourteen-digit HU map will replace the 1974 eight- digit HU map [U.S. Water Resource Council (WRC)] and the 1978 NRCS eleven-digit HU map as the locating tool for planning in NRCS. The 1995 HU map were produced using 7.5 minute USGS quadrangle base maps (1:24,000 scale).

NOTE: The subbasin 6-digit code (SUBBASIN#) was developed independently from the hydrologic unit codes, from an entirely different numbering system. (Example of code: 03-03-01.) The first two numbers identify the river basin designations adopted by the Environmental Protection Agency. (Date of source: 1974.) Subbasin boundaries were added within individual river basin boundaries (by the office that is now known as the Division of Water Quality, Water Quality Planning Section). Sequential numbers (example -01) were added by DWQ to the first four-digit EPA code to give each subbasin a unique six-digit identifier. (Each subbasin incorporates three or more hydrologic units. The subbasin boundaries have been modified to be coincident with the hydrologic unit boundaries.) Contact Alan Clark at DWQ for more information on the subbasin# code (733-5083, extension 570).

(huncrb and huncsb need to be updated whenever hunc is updated).

Revisions and updates to this layer include:
4.) filename: hunc1298  The December 1998 update to this layer
consisted of projecting the data from NAD27 datum, State Plane
projection, units of measure feet TO: NAD83 DATUM, State Plane
PROJECTION, UNITS OF MEASURE METERS.  This was done to comply
with the NC Geographic Information Coordinating Council's
"Statement of Direction for North Carolina Corporate Geographic
Database Horizontal Reference, Datum and Unit of Measure".  This
reprojecting was done in various ways depending on the data type
and content.  Vector data was projected using the 'project' command
in ESRI's Arc software and topology was cleaned and built based on
coverage needs.  Raster data was projected using ESRI's Grid module
and various steps as applicable.

3.)filename: hunc496   The April 15, 1996 update included
restoring the Arc Attribute Table (AAT) to the coverage.  This
was lost while processing the file for river basins and subbasins
attributes. It also included names and 6-digit identification
numbers added for subbasins as well as names and abbreviations
added for river basins.  Some minor boundary adjustments were made
throughout the coverage to make the Hydrologic Units boundaries
coincident with the Water Supply Watershed boundaries.

2.) filename: nc24hu1194  This is the first version of the
hydrologic units as studied by NCDWQ and NRCS, statewide.

1.) filename: cam24.hu1194  This file contains only the coastal
area of NC, and has been superceded by the full state coverage.

  2. How were the data generated, processed, and modified?

    Date: 30-Nov-1994 (process 1 of 4)
    Hydrologic Units were delineated on USGS 1:24,000 paper topographic maps by following contour lines. HU codes were written onto the topo maps for later attribute coding. All topo maps within the Coastal Area Management Act (CAMA) area were given to CGIA for digitization. All other topos across the state were given to Westinghouse-Landmark GIS, Inc. for digitization. The USDA-Natural Resources Conservation Service delineated the hydrologic units for North Carolina on 24k USGS topographic maps. The digital files were plotted by CGIA and overlayed to the originals and reviewed by staff at NRCS and DENR-DWQ. Needed corrections were made. Once an agreed upon, digital file was created. DWQ assisted NRCS in modifying certain boundaries which were not at the time coincident with the subbasins that DWQ manages. After that was completed, NRCS met with officials from neighboring states (Virginia, South Carolina, Georgia, and Tennessee) to edgematch the Hydrologic Unit boundaries across the state line. This was done to the 11-digit boundary, not the 14-digit. Once this file was complete, DWQ assisted CGIA in establishing new subbasin boundaries derived from HU boundaries, and then established new river basin boundaries derived from subbasin boundaries. This digital file is updated as changes occur.

    Hydrologic units were digitized from hand delineated boundaries on USGS 7.5 Minute series paper base maps. The digital files were attributed and checkplots were created for review by the Natural Resources Conservation Service and the NC Division of Water Quality. Necessary corrections were made and new plots were run. Post processing involved edgematching and mapjoining of USGS 7.5 Minute series maps used to create the digitized data. This process generated one statewide polygon coverage. CGIA updates the digital file as needed.

How reliable are the data; what problems remain in the data set?

  1. How well have the observations been checked?

    The USDA-Natural Resources Conservation Service delineated the hydrologic units for North Carolina on 24k USGS topographic maps. These boundaries were attributed with USDA-NRCS classification information, acres per polygon, and square miles per polygon. The digital files were plotted and overlayed to the originals and linework and label corrections were made. Once complete and under the direction of DENR-DWQ, the digital file was further defined by subbasins derived from HUs and the river basins derived by subbasins. Appropiate ids were added to the attribute files. Attribute accuracy is considered high. There are no lookup tables, annotation or cartosets for this data.

  2. How accurate are the geographic locations?

    Hydrologic Units for North Carolina were delineated on 7.5 Minute USGS paper topographic maps which meet National Map Accuracy Standards, using a best estimate with reference to surrounding features. Boundaries drawn were digitized and checkplots were used to ensure correct boundary location, within a line-width.

  3. How accurate are the heights or depths?

  4. Where are the gaps in the data? What is missing?

    These data depict the boundaries and unit numbers from the USDA-NRCS Hydrologic Unit River Basin Study, 1995. The study divides the state river basins into subbasins used to track resource and conservation activities.

  5. How consistent are the relationships among the observations, including topology?

    Using ESRI's ARC/INFO GIS software, the data set was built for arc and polygon topology using the "build" command. The data set was then cleaned with a fuzzy tolerance of 1 foot. Topology has not been edited since the last build or clean.

How can someone get a copy of the data set?

Are there legal restrictions on access or use of the data?
