EOMF-14. Continuously Updated Digital Elevation Models (CUDEMs) supporting coastal inundation modeling programs - Current Status and Future Plans

The National Oceanic and Atmospheric Administration (NOAA) National Centers for Environmental Information (NCEI) develops coastal digital elevation models (DEMs) by integrating bathymetric and topographic elevation data to generate a continuous earth surface at the coast. These DEMs support coastal inundation modeling as part of the Consumer Option for an Alternative System To Allocate Losses (COASTAL) Act and the National Tsunami Hazard Mitigation Program (NTHMP). The CIRES DEM team at NOAA NCEI will present a summary of this last year’s DEM development progress, which includes completing coverage of the U.S. East and Gulf Coasts, portions of Alaska’s Cook Inlet, Guam, and American Samoa. The completed DEMs are accessible via NCEI’s collaboration with the NOAA Office for Coastal Management’s (OCM) Digital Coast Data Access Viewer along with ancillary DEM data products (e.g., spatial metadata). Ongoing and future DEM developments in data products and updates to DEM generation code will also be presented.
