Abstract: The Sea Level Rise Viewer, available at NOAA’s Digital Coast, has been updated for TX, LA, FL, SC, and areas of WA. A total of 15 new Digital Elevation Models (DEMs) were updated and are available for download, in addition to the mapping outputs for Sea Level Rise, Mapping Confidence, Marsh Migration, and High Tide Flooding. A total of 46 map services were updated with the new data. Areas with older and lower resolution data sets have been updated, with most areas now at 3-meter resolution. Users can now zoom in further to see community level impacts. The High Tide Flooding graphics have now been updated to reflect the latest Annual High Tide Flood report. Additionally, photo-realistic simulations for select locations are now viewable for the 7-10FT sea level intervals and 35more simulations will be added soon.

The Sea Lever Rise Viewer enables users to visualize potential impacts from sea level rise through maps, regional projections, and photos. They can also download all data and obtain mapping methods, as well as share maps and links via social media.

In addition, there are other publicly-available sources for SLR data and visualizations that provide users with similar options and functionality.Several of these will be highlighted and discussed.


Douglas (Doug) C. Marcy is a Coastal Hazards Specialist at the NOAA Office for Coastal Management in Charleston, SC. He has been with the NOAA 18 years working on flooding and sea level rise geospatial mapping projects, storm surge assessments, and coastal hazards assessment projects contributing to more disaster resilient communities. He worked as a Hydraulic Engineer with the U.S. Army Corps of Engineers, Charleston District from 1999 to 2002, where he focused on flood control projects, H&H modeling, flood inundation mapping, shoreline change analysis, and coastal engineering. From 1997 to 1999 Doug worked at the South Carolina Office of Ocean and Coastal Resource Management. Doug has a M.S. in marine geology (1997) from the University of North Carolina at Wilmington and a B.S. in geology (1994) from the College of Charleston. Doug’s current interests include using geospatial technology combined with meteorological, hydrological, and coastal modeling (including sea level change) to enhance inundation forecasting, mapping, and risk assessment.

William (Billy) Brooks is a senior geospatial analyst with Lynker on contract at the NOAA Office for Coastal Management. He has been at NOAA OCM for over 19 years and has worked on a variety of resilience, inundation, and elevation projects, including NOAA’s Sea Level Rise and Lake Level Viewers. His current work focuses on using multiple data sources and visualization techniques to communicate the potential impacts of increased water levels on coastal communities.
