NOAA Sea Level Rise and Coastal Flooding Impacts Data and Viewer

Published by Office for Coastal Management | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: September 01, 2026 at 10:42 PM | Dataset Last Updated: January 01, 2014 at 12:00 AM
This aggregate metadata record describes the underlying geospatial datasets and the associated NOAA Sea Level Rise and Coastal Flooding Impacts Viewer application. The data, hosted via the NOAA Open Data Dissemination (NODD) program on a cloud service provider (Azure), includes high-resolution digital elevation models (DEMs), shallow coastal bathymetry, mapping confidence, marsh migration modeling, and sea level rise inundation depth surfaces for various SLR scenarios. These datasets cover U.S. coastal states (except for Alaska, Louisiana, and Great Lake states) and the U.S. territories of Guam, Puerto Rico, Saipan, and the U.S. Virgin Islands. The associated Sea Level Rise and Coastal Flooding Impacts Viewer is an interactive, screening-level application that leverages these nationally consistent data sets and analyses to depict potential sea level rise and its associated impacts on the nation's coastal areas. The viewer provides coastal managers and scientists with a web-based, preliminary look at sea level rise (slr) and coastal flooding impacts without needing specialized GIS software. The underlying bulk data can be downloaded directly for detailed, localized geospatial analysis, while the viewer serves as a powerful teaching and planning tool for coastal communities. The viewer may be accessed at: http://www.coast.noaa.gov/slr/ and the bulk data via: https://coast.noaa.gov/htdata/Inundation/SLR/BulkDownload/index.html. Key features of this dataset and tool include: 1. Displays potential future sea levels 2. Provides simulations of sea level rise at local landmarks 3. Communicates the spatial uncertainty of mapped sea levels 4. Models potential marsh migration due to sea level rise 5.Overlays social and economic data onto potential sea level rise 6. Examines how tidal flooding will become more frequent with sea level rise.
