Atmospheric Administration Coastal Services Center's efforts to create an
online mapping viewer depicting potential sea level rise and its associated
impacts on the nation's coastal areas. The purpose of the mapping viewer is to
provide coastal managers and scientists with a preliminary look at sea level
rise (slr) and coastal flooding impacts. The viewer is a screening-level tool
that uses nationally consistent data sets and analyses. Data and maps provided
can be used at several scales to help gauge trends and prioritize actions for
different scenarios. The Sea Level Rise and Coastal Flooding Impacts Viewer may

These data depict the potential inundation of coastal areas resulting from a
projected 1 to 6 feet rise in sea level above current Mean Higher High Water
(MHHW) conditions. The process used to produce the data can be described as a
modified bathtub approach that attempts to account for both local/regional
tidal variability as well as hydrological connectivity. The process uses two
source datasets to derive the final inundation rasters and polygons and
accompanying low-lying polygons for each iteration of sea level rise: the
Digital Elevation Model (DEM) of the area and a tidal surface model that
represents spatial tidal variability. The tidal model is created using the NOAA
National Geodetic Survey's VDATUM datum transformation software (</font><a href='http://vdatum.noaa.gov/'><font color='#0000ff' face='Calibri' size='3'>&lt;http://vdatum.noaa.gov&gt;</font></a><font color='#000000' face='Calibri' size='3'>) in
conjunction with spatial interpolation/extrapolation methods and represents the
MHHW tidal datum in orthometric values (North American Vertical Datum of 1988).
The model used to produce these data does not account for erosion, subsidence,
or any future changes in an area's hydrodynamics. It is simply a method to
derive data in order to visualize the potential scale, not exact location, of
inundation from sea level rise<br /></font><font face='Calibri'><font color='#000000' size='3'>
