Integrated Models of Coastal Relief

NCEI builds and distributes high-resolution, coastal digital elevation models (DEMs) that integrate ocean bathymetry and land topography to support NOAA's mission to understand and predict changes in Earth's environment, and conserve and manage coastal and marine resources to meet our Nation's economic, social, and environmental needs. They can be used for modeling of coastal processes (tsunami inundation, storm surge, sea-level rise, contaminant dispersal, etc.), ecosystems management and habitat research, coastal and marine spatial planning, and hazard mitigation and community preparedness.

Coastal Inundation (high-resolution, 1 arc-second or finer)
  • Hurricane Sandy DEMs
    Suite of high-resolution DEMs of the U.S. Atlantic Coast impacted by Hurricane Sandy in October 2012.

  • NOAA Tsunami Inundation DEMs
    High-resolution DEMs of select U.S. coastal communities used to support NOAA's tsunami forecast and warning system.

  • NOAA VDatum DEMs
    High-resolution DEMs of select U.S. coastal communities along the central coast of the Gulf of Mexico used to evaluate and support NOAA's Vertical Datum Transformation Tool (VDatum).
