Coastal Elevation Models from NOAA/NCEI
Named by primary coastal city, state in DEM.
Digital elevation models (DEMs) of U.S. and other coasts that typically integrate ocean bathymetry and land topography. The DEMs 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. NOAA's National Centers for Environmental Information (NCEI) has built many of these models, and also distributes DEMs on behalf of other NOAA offices, as well national and international partners. Bathymetric, topographic, and shoreline data used in DEM development come from a variety of sources, including NOAA's National Ocean Service (NOS) and NCEI, the U.S. Geological Survey (USGS), the U.S. Army Corps of Engineers (USACE), and the Federal Emergency Management Agency (FEMA), as well as other federal, state, and local government agencies, academic institutions, and private companies. The DEMs are referenced to a variety of vertical tidal datums, typically mean high water (MHW) or North American Vertical Datum of 1988 (NAVD 88), and usually a horizontal datum of North American Datum of 1983 (NAD 83) or World Geodetic System 1984 (WGS84). DEM cell sizes range from high-resolution models (1/9 to 1/3 arc-second; ~3 to 10 meters) that support coastal inundation studies, to regional models (roughly 3 to 24 arc-seconds) that extend farther offshore, to global models (1 arc-minute; ~2 km).
The DEMs 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.

Digital Elevation Models Mosaic (Individual DEMs)
An image service providing access to bathymetric/topographic digital elevation models stewarded at NOAA's National Centers for Environmental Information. Either individual DEMs or small subsets can be accessed through this service.

publisher
The DEM Global Mosaic is an image service providing a global, seamless bathymetry/topography mosaic that includes NCEI's ETOPO 2022, NCEI's Continuously Updated DEM (CUDEM), and other NCEI-stewarded DEMs, along with regional grids such as IBCAO, IBCSO and the Hawaiian Island Multibeam Synthesis (University of Hawaii). This service provides elevation/depth values in meters; for a visualization of the data, please see the related DEM Global Mosaic (Color Shaded Relief) service. There are 5 related image services providing access to Digital Elevation Models: DEM Mosaic (Individual DEMs), DEM Global Mosaic (Elevation Values), DEM Global Mosaic (Color Shaded Relief), CUDEM Mosaic (Elevation Values), and CUDEM Mosaic (Color Shaded 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. This service is a general-purpose global, seamless bathymetry/topography mosaic. It combines DEMs from a variety of near sea-level vertical datums, such as mean high water (MHW), mean sea level (MSL), and North American Vertical Datum of 1988 (NAVD88). No conversion/harmonization of vertical datums was performed. Because the mosaic contains 'overviews' for performance, individual DEMs cannot be separated from the others. Individual DEMs, or smaller subsets, are available in the companion DEM Mosaic (Individual DEMs) image service. By default, the DEMs are drawn in order of cell size, with higher-resolution grids displayed on top of lower-resolution grids. If overlapping DEMs have the same resolution, the newer one is shown. Please see NCEI's corresponding DEM Footprints feature service for polygon footprints and more information about the individual DEMs used to create this composite view.

NOAA National Centers for Environmental Information
NOAA created the National Centers for Environmental Information (NCEI) by merging NOAA's National Climatic Data Center (NCDC), National Geophysical Data Center (NGDC), and National Oceanographic Data Center (NODC), including the National Coastal Data Development Center (NCDDC), per the Consolidated and Further Continuing Appropriations Act, 2015, Public Law 113-235. NCEI launched publicly on April 22, 2015.
