Item Identification

Title: North Carolina 2016 HYDRO Polygons
Short Name: North Carolina 2016 HYDRO Polygons
Status: Completed
Publication Date: 2016

This data set contains vector polygons representing the coastal shoreline and hydrography used in the creation of the Environmental Sensitivity Index (ESI) for North Carolina. As a whole, the ESI data characterize the marine and coastal environments and wildlife by their sensitivity to spilled oil, and include information for three main components: shoreline habitats, sensitive biological resources, and human-use resources. See also the HYDROL (Hydrography Lines) data layer for additional shoreline/hydrography information.


The ESI data are intended to provide baseline environmental data for oil spill planning and response. The Clean Water Act with amendments by the Oil Pollution Act of 1990 requires response plans for immediate and effective protection of sensitive resources. The ESI data may be appropriate for many other coastal management efforts, though the original intent should be kept in mind.

Distribution Liability:

Although these data have been processed successfully on a computer system at the National Oceanic and Atmospheric Administration (NOAA), no warranty, expressed or implied, is made by NOAA regarding the utility of the data on any other system, nor shall the act of distribution constitute any such warranty. NOAA warrants the delivery of this product in computer-readable format. If problems are encountered in downloading the ESI data or with file corruption, contact NOAA (see Distributor). These data represent a snapshot in time and temporal changes may have occurred. The data are not intended to include all biological or human-use resources present in an area; they focus on species and resources particularly sensitive to oiling. In the event of a spill, they should be used for a first assessment only. The data providers are the experts with regard to individual resources. They should be contacted to confirm if more current data exist or if in-depth information is needed about a particular resource.

Data Access Constraints:


Data Use Constraints:

DO NOT USE MAPS FOR NAVIGATIONAL PURPOSES. Management boundaries are not to be considered legal boundaries. Edges may have been altered for cartographic processes. Note that the ESI database should not be used to the exclusion of other pertinent data or information held by state or federal agencies or other organizations. Likewise, information contained in the database cannot be used in place of consultations with environmental, natural resource, and cultural resource agencies, or in place of field surveys. Recognize that the information contained in the ESI database represents known concentration areas or occurrences of natural, cultural, and human-use resources, but does not necessarily represent the full distribution or range of each species or resource. This is particularly important to recognize when considering potential impacts to protected resources, such as endangered species, wetlands, etc. Besides the above warnings, there are no use constraints on these data. Acknowledgement of the originators, publishers, contributors, and sources listed would be appreciated in products derived from these data.

Technical Environment


The software packages used to develop the atlas are Environmental Systems Research Institute's ArcGIS for Desktop 10.2(R) and SQL SERVER(R) (version 2005). The hardware configuration is PCs with Windows Operating System 7.

Data Quality


A multi-stage error checking process is used to verify both attribute accuracy and logical consistency throughout data production. The process includes a standardized data entry methodology, data review by in-house and external resource experts, a final Quality Assurance/Quality Control (QA/QC) process, and multiple automated logical consistency checks. Quantitative data (such as densities, counts, abundances, or concentrations) provided by resource experts for inclusion in the data set may vary widely in attribute accuracy, depending upon the methodology used to collect and compile such data. For a more detailed evaluation of source data attribute accuracy, contact the sources listed in the Lineage section.

Completeness Report:

These data represent polygonal hydrography for North Carolina. See also the HYDROL (Hydrography Lines) data layer for additional shoreline/hydrography information.

Conceptual Consistency:

A multi-stage error checking process, described in the above Attribute Accuracy Report, is used to verify both attribute accuracy and logical consistency throughout data production. This process includes multiple automated logical consistency checks that test the files for missing or duplicate data, rules for proper coding, GIS topological consistencies, and SQL SERVER(R) to ArcGIS(R) consistencies. A final review is made by the GIS manager, before the final Geodatabase and metadata are created. After the data are delivered to NOAA, they are again subjected to several consistency checks, and processed into the final delivery format.


Process Steps

Process Step 1

CC ID: 591431

The shoreline locations and features were derived from the integration of the following digital data: National Oceanic and Atmospheric Administration (NOAA) Continually Updated Shoreline Product (CUSP) (2014); NOAA Shoreline Mapping Program NC1401A / NC0801A / NC0801D / NC0902 / NC0503 / NC0501 (20140604) datasets; the North Carolina Division of Coastal Management (DCM) Estuarine Shoreline (1:300/1:500) (2012) dataset; the U.S. Geological Survey (USGS) National Hydrography Dataset (NHD) (2014); the U.S. Fish and Wildlife Service (USFWS) National Wetlands Inventory (NWI) dataset (2010); the NOAA, National Ocean Service (NOS), Office of Response and Restoration (OR&R), Emergency Response Division(ERD) and U.S. EPA, Department of Homeland Security (DHS), U.S. Coast Guard (USCG) Sensitivity of Coastal Environments and Wildlife to Spilled Oil - North Carolina (201107) dataset; and manual digitization at approximately 1:1,000 scale using ortho-rectified aerial imagery resources from the North Carolina Center for Geographic Information and Analysis (2012), Environmental System Research Institute (ESRI) World Imagery (2014), and the NOAA Ortho-rectified Mosaic of Eastern Coastline - Hurricane Sandy Impact Area (20141023).

The HYDROP data layer was created using the ESIL "shoreline" [LINE] types and the atlas area of interest (AOI) extent. Using the ArcGIS Feature to Polygon tool, the ESIL shorelines, the NWI inland waterbodies, and the AOI were integrated to create HYDROP land and water polygons. The land and water designations were identified using a series of spatial queries. The data were checked for logical consistency errors and topology errors. The ESI, biology, and human-use data were compiled into the standard ESI digital data format. A QA/QC period for NOAA and participating resource experts was conducted and, as needed, edits to the HYDROP data layer were made based on the recommendations of the experts, and final hardcopy maps and digital data were created.
