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.

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.
