Identification_Information: Citation: Citation_Information: Originator: National Hurricane Center Publication_Date: 19990903 Title: Hurricane Storm Surge Areas - "Slow" Moving Storms Geospatial_Data_Presentation_Form: vector digital data Publication_Information: Publication_Place: Coral Gables, Florida Publisher: National Hurricane Center Other_Citation_Details: NCCGIA distributes this dataset Online_Linkage: www.nconemap.com Description: Abstract: The National Hurricane Center, in cooperation with the North Carolina Center for Geographic Information and Analysis, developed the GIS data set, Hurricane Storm Surge Inundation Areas (1993), to reevaluate the extent of the areas affected by hurricane inundation along the North Carolina coast. The data depicts the extent of hurricane storm surge inundation areas based on SLOSH (Sea, Lake, and Overland Surges from Hurricanes) models, for the North Carolina coast. This is the metadata for the SLOW model (with forward velocities of less than or equal to 15mph). Storm surge is the abnormal rise in water level caused by wind and pressure forces of a hurricane or tropical storm. The SLOSH model was developed using various combinations of hurricane strength (based on the Saffir-Simpson scale), wind speed, and direction of movement. Rainfall produced by a hurricane is not taken into account. This data is stored in a county library by county extent. Purpose: This data was created to assist governmental agencies and others in making resource management decisions through use of a Geographic Information System (GIS). Supplemental_Information: There are several county-based coverages associated with this data layer. The county names below show inundation limit file sizes for the 'slow' hurricanes (with forward velocities of less than or equal to 15mph). There are coverages depicting inundation limits for the 'fast' hurricanes (those with forward velocities greater than 15mph) as well. >Revisions and updates to this layer include: >6.) filenames: (countyabbrev)hss93s999, one metadata file. >Sept. 3, 1999: Updated one polygon coding error for surge value >in Dare County. >5.) directory: hss93_799 filenames: (countyabbrev)hss93s799 >(countyabbrev)hss93f799 >July 21, 1999 update includes surge updates for the following counties: >Carteret and Onslow.

Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: All attributes were supplied by the National Hurricane Center Overlays labeled with attribute information were digitized and the attributes transferred to the digital file. Check plots were made and overlayed to the originals to check attribute accuracy. Logical_Consistency_Report: Using ESRI's ARC/INFO GIS software, the dataset was built for arc and polygon topology using the "build" command. The data set was then cleaned using the "clean" command. Topology has not been edited since the last build or clean. Completeness_Report: These data show the extent of hurricane storm surge inundation areas based on SLOSH (Sea, Lake, and Overland Surges from Hurricanes) for the North Carolina coast based on a National Hurricane Center 1993 study. There are two coverages associated with the data layer: one showing limits for the 'fast' hurricanes and one showing limits for the 'slow' hurricanes. The areas are labeled according to hurricane strength (on the Saffir-Simpson scale) measured by movement at miles per hour. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Hurricane storm surge inundation areas were marked onto a third overlay, with 7.5 Minute USGS paper topographic maps (which meet National Map Accuracy Standards) and SLOSH plots underneath. Boundaries drawn on the third overlay were digitized and check plots used to ensure correct boundary location, within a line width.

Process_Step: Process_Description: SLOSH models, provided by the National Hurricane Center, and USGS topographic maps, both at 1:24,000 and with contour lines, were overlayed and inundation interpolation was done onto a third overlay. The third overlay contained the limits of inundation according to categories 1 and 2, category 3, and categories 4 and 5 hurricanes. Each limit, which was differentiated by color, was then digitized. Check plots were made and overlayed to the originals for accuracy to a pen width of the original linework. Any necessary corrections were made. The coverages were then appended.
