Title: North Carolina 2016 NATURAL HAZARD Polygons
Short Name: North Carolina 2016 NATURAL HAZARD Polygons
Status: Completed
Publication Date: 2016
Abstract:

This feature class resides within the SOCECON Feature Data Set of the North Carolina 2016 ESI geodatabase. It contains vector polygons representing Natural Hazard human-use resource data for marine and estuarine waters of North Carolina and adjacent lands and waters.

The vector polygons represent predicted flood inundation in the event of a Category 1, 2, 3, 4, or 5 storm. For each storm category, the level of flooding is binned into anticipated depth of flood waters: <= 3 feet, > 3 feet, > 6, and > 9 feet. These are modeled data, based on the National Hurricane Center’s Sea, Lake and Overland Surges from Hurricanes (SLOSH) model (https://www.nhc.noaa.gov/surge/slosh.php). Raster model data, prepared in 2015, was converted to vector polygons for the purpose of the ESI. These data should be used for planning purposes only.

The ArcGIS feature class (NATURAL HAZARD POLYS) has 2 associated attribute tables, considered as Entities or "Child Items" in this metadata record. Location-specific Type and Source information are stored in these related data tables, SOC_DAT and SOURCES (described below), which are stand-alone tables within the Geodatabase.

This data set is a portion of the ESI data for North Carolina - 2016. 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.

Additional human-use information is provided in other feature class themes within the SOCECON Feature Data Set, including NAVIGATION/MARINE (POINTS, LINES, and POLYGONS), PARKS/MANAGED AREA (POINTS and POLYGONS), POLITICAL/JURISDICTIONAL (POINTS and POLYGONS), RESOURCE MANAGEMENT (POINTS and POLYGONS), and SOCECON (POINTS AND POLYGONS).

Purpose:

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 purposes, though the original intent should be kept in mind.

Data Presentation Form: Map (digital)
Entity Attribute Overview:

In addition to the geographic data layers, two associated data tables, SOC_DAT and SOURCES, are used to store the complex socioeconomic data in the ESI data structure. The geographic data layers containing socioeconomic data resource information (in this case, NATURAL HAZARD POLYS) are linked to the Socioeconomic Resources table (SOC_DAT) using HUNUM. HUNUM is a unique reference number concatenated with the atlas number, making it unique across ESI atlas regions. For North Carolina - 2016, the atlas number is 335).

The SOC_DAT and SOURCES data tables are described in detail in this document as Entities or "Child Items". See the Browse_Graphic section for a link to the entity-relationship diagram, which describes the way these tables relate to the geographic data layers and other attribute tables in the ESI data structure.

Data Quality

Accuracy:

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, check the sources listed in the Lineage section.

Completeness Report:

These data represent modeled output provided by the National Hurricane Center, 2015. Raster data was converted to vector polygons by NOAA/NOS OR&R Emergency Response Division.

For additional human-use information, see other feature class themes within the SOCECON Feature Data Set, including NAVIGATION/MARINE (POINTS and LINES), PARKS/MANAGED AREA (POINTS and POLYGONS), POLITICAL/JURISDICTIONAL (POINTS and POLYGONS), RESOURCE MANAGEMENT (POINTS and POLYGONS), and SOCECON (POINTS AND LINES).

These data do not necessarily represent all Natural Hazard features in the North Carolina ESI study area.

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 a several consistency checks, and processed into the final delivery format.

Process Steps

Process Step 1

CC ID: 775828
Description:

The original NHC SLOSH data was a raster data layer with a geographic extent from Maine to Texas. The first process step was to subdivide the source raster data into geographic regions corresponding to an area slightly larger than the ESI region’s geographic extent. The resultant data were then converted to polygons within Arcmap, using the conversion tool Raster to Polygon.

Process Step 2

CC ID: 775829
Description:

A tool was developed, automating the next several steps to ensure consistency. The SLOSH polygon data were projected into the appropriate UTM zone, then clipped to the ESI shoreline and converted from multipart to singlepart polygons. The resultant polygons were unioned with a universal polygon representing the entire area of interest. This step enables identification of SLOSH polys that do not correspond to land (either due to the vectorization process or because of differences between the SLOSH model’s shoreline and the ESI shoreline); these polygons are coded for deletion. Area, perimeter and ratio (area/perimeter) is calculated all polygons.

Process Step 3

CC ID: 775832
Description:

A field, “INUNDATION”, is added to the feature data table, and a value of “<= 3 ft”, “> 3 ft”, “> 6 ft”, “> 9 ft” calculated based on the grid code value from the raster data set. Small (slivers resulting from vectorization) polygons, not assigned an inundation value, are selected and eliminated – merged with the largest adjacent polygon.

Email Address: orr.esi@noaa.gov

Process Step 4

CC ID: 775830
Description:

Shoreline gaps are identified. These are polygons that 1) do not have an inundation value, 2) share a boundary with the shoreline, and 3) share boundaries with polygons that do have an inundation value. These polygons may represent areas where the vectorized SLOSH data did not extend to the shoreline either because of shoreline differences of the raster-vector process. A conservative method was used to avoid attributing shoreline with potential flooding where it was not intended. Only features that had an area of less than 8500 square meters and an area/perimeter ratio less than 15 were selected. These polygons were dissolved into the adjacent flood polygon with the longest length. Because this process was conservative, there are several places where the land nearest the shoreline is not shown as flooding. This is likely not the case, and users need to be aware that these types of areas and small islands may erroneously not highlight flooding potential. Use judgement and consider the flood potential of nearby regions.
