Zachry, B. C., W. J. Booth, J. R. Rhome, and T. M. Sharon, 2015: A National View of Storm Surge Risk and Inundation. Weather, Climate, and Society, 7(2), 109–117. DOI: http://dx.doi.org/10.1175/WCAS–D–14–00049.1

Storm surge hazard maps are available for Texas to Maine and Puerto Rico. The data are available in GeoTIFF (http://trac.osgeo.org/geotiff/) format for use in Geographic Information Systems (GIS) software. Comprehensive metadata are provided with each GIS file describing the data and its limitations. Storm surge inundation datasets are created using the high tide scenario SLOSH MOM products for all regions. Each dataset contains an ESRI World File (.tfw) and metadata .xml file. These GeoTIFFs are 8-bit unsigned integer raster datasets that correspond to 1 ft inundation bins (e.g., Class Value 1 corresponds to the 0-1 ft inundation bin, Class Value 2 corresponds to the 1-2 ft inundation bin, and so on). The maximum Class Value is 21, and inundation in excess of 20 ft is assigned a Class Value of 21. A Class Value of 99 is assigned to leveed areas. A more detailed description of the data can be found in the associated metadata.
