This DEM Mosaic is an image service providing access to the newer Continuously Updated Digital Elevation Model (CUDEM) bathymetric/topographic digital elevation models stewarded at NOAA's National Centers for Environmental Information (NCEI). This service provides elevation/depth values in meters; for a visualization of the data, please see the related CUDEM Mosaic (Color Shaded Relief) service.
There are 5 related image services providing access to Digital Elevation Models:
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. For more information about coastal DEMs at NCEI, please see: https://www.ncei.noaa.gov/products/coastal-elevation-models or learn more from our DEM Fact Sheet (1 MB PDF).
The DEMs can be viewed in NCEI's Bathymetric Data Viewer along with other bathymetric datasets stewarded at NCEI.
Please see NCEI's corresponding DEM Extents feature layer for polygon footprints and more information about the individual DEMs used to create this composite view. The newer 1/3 and 1/9 arcsecond "tiled" DEMs are hosted by NOAA's Office for Coastal Management; please see the Data Access Viewer for access to these data.
