U.S. Department of Agriculture, North Carolina Natural Resources Conservation Service State Office 03152005 Unknown 1 vector digital data Raleigh, North Carolina Natural Resources Conservation Service NCCGIA distributes this dataset withheld Stormwater_Basins_Clipped This data set is a complete digital hydrologic unit boundary layer to the Subwatershed (12-digit) 6th level for Cabarrus County. This data set consists of geo-referenced digital data and associated attributes created in accordance with the "FGDC Proposal, Version 2.0 - Federal Standards For Delineation of Hydrologic Unit Boundaries 8/30/04"(http://www.ftw.nrcs.usda.gov/huc_data.html). Polygons are attributed with hydrologic unit codes for 4th level sub-basins, 5th level watersheds, 6th level subwatersheds, name, size, downstream hydrologic unit, type of watershed, non-contributing areas and flow modification. Arcs are attributed with the highest hydrologic unit code for each watershed, linesource and a metadata reference file. The Watershed and Subwatershed hydrologic unit boundaries provide a uniquely identified and uniform method of subdividing large drainage areas. The smaller sized 6th level sub-watersheds (up to 40,000 acres) are useful for numerous application programs supported by a variety of local, State, and Federal Agencies. This data set is intended to be used as a tool for water-resource management and planning activities, particularly for site-specific and localized studies requiring a level of detail provided by large-scale map information. The dataset will be appended to a larger seamless nationally consistant geospatial database as other states complete their portion of the watershed boundary dataset. system filename: ncWBD83m.xml file format: ESRI ArcGIS 9.0 Geodatabase export file file size: 37 mb (zipped), 60 mb (unzipped) en 20050309 Publication date of sources Complete Unknown -80.862879 -80.185530 35.640519 35.173028 1446480.691964 1645770.961855 523064.789907 690174.759398 None HUC Hydrologic Units Hydrologic Unit Code Region Sub-region Basin Sub-basin Watershed Watershed Boundaries boundaries Subwatershed WBD Watershed Boundary Dataset None North Carolina Cabarrus None The distributor shall not be held liable for improper or incorrect use of this data, based on the description of appropriate/inappropriate uses described in this metadata document.

Funding for the North Carolina Watershed Boundary Dataset (WBD) was provided by the U.S. Department of Agriculture-Natural Resources Conservation Service, North Carolina Department of Environment and Natural Resources (NCDENR)-Division of Coastal Management, and the US Geological Survey. Representatives from the NCDENR-Division of Coastal Management, NCDENR-Division of Land Resources-Geological Survey, NCDENR-Division of Water Quality, NCDENR-Division of Water Resources, NCDENR-Division of Water Resources-Groundwater Section, NCDENR-Center for Geographic Information and Analysis, US Geological Survey (USGS), National Oceanic and Atmospheric Administration (NOAA), and US Fish and Wildlife Service contributed a substantial amount of time and salary towards oversight and quality review of the dataset. Special recognition goes to Randy Ferguson (NOAA), Ted Mew (NCDENR), Kathleen Farrell (NCDENR), Alan Clark (NCDENR) and Silvia Terziotti (USGS) who contributed greatly of their time and expertise to guide this project and develop the science necessary to produce this product. ESRI ArcCatalog 9.3.1.3000 Shapefile There are no unclosed polygons, intersections without nodes, or polygons without labels or with more than one label. Arc/Info's topological correction program CLEAN was used to correct intersections without nodes, identify unclosed polygons and remove duplicate lines with the same beginning and ending nodes. All sliver polygons were removed either using eliminate, merge or manually in ArcEdit. All fields for all polygons in the .pat are attributed. Some polygons in the Ncontrb_a field might have a 0 value. All fields for the lines in the .aat are attributed. The lines adjacent to the universal polygon are attributed with a 0 for the hu_level. These cannot be attributed until the adjacent states complete their linework at which point the highest level of hydrologic unit can be determined. The WBD was produced using either Enhanced Digital Raster Graphics (DRG-Es) digital images as source map for land data (current work in 2002-2005) or data manually digitized from paper USGS quadrangle maps (previous work in 1993-1994). The WBD for North Carolina was started in 1993 using paper USGS quad maps and digitized into the NC Coordinate system, feet, NAD27. All edits since then have also used this Coordinate base. Maps in other coordinate systems were produced using the ArcInfo 9 project utility from this base map. The WBD used NOAA Nautical Charts for over-water data, when the DRG-Es were not adequate. Data completeness for DRG files reflect content of the source graphic and may therefore be reflected in the completeness and accuracy of the WBD. The map was digitized from USGS 1:24,000-scale digital raster graphic base maps, with an inherited error of +/- 40 feet according to USGS National Map Accuracy Standards. A shift of up to 150 feet (varies from quad to quad and across the state) was noted between lines placed on the previously used paper USGS quadrangle maps when compared to the currently used DRG-Es computer maps. This map was originally digitized from paper USGS quadrangle maps in 1994 and revised with the newer DRG-Es computer maps for this data. Approximately half of the lines are from the old paper USGS quadrangle maps and will have a greater line placement error when compared to the DRG-Es base. Digitized line locations were held to the +/- 40 foot accuracy standards for current work by ensuring that all lines were within a 12 meter buffer of where visual interpretation put the actual boundary. Any lines outside the buffer were corrected. It is estimated that the errors detected were less than 10%. It should be noted that while general rules of hydrology were used (i.e. water flows downhill), the location of boundaries is still somewhat subjective as the 1:24,000-scale DRG-E do not always provide enough information for identifying the location of the boundaries. In these instances group consensus was used. In the extremely flat areas located in the coastal plains of North Carolina, boundaries were adjusted for drainage effects. Please refer to the methods section for more details on watershed delineation rules. Unquantifiable errors may be associated with coordinate shift (fuzzy tolerance was set to 0.0001 meters, double precision), dangle (set to 15 meters). The default was used for all other ArcEdit tolerances. As with the original DRGs, DRG-E is cast in the Universal Transverse Mercator projection and is referenced to the NAD27 datum. When the drg-es are used in the NAD83 datum the alternate world files only approximate the NAD83 by shifting the coordinates of the imagery. The total error introduced using this shift is less than 2 meters for all DRG-E imagery.
