The National Oceanic and Atmospheric Administration (NOAA) National Centers for Environmental Information (NCEI), in collaboration with the Cooperative Institute for Research in Environmental Sciences (CIRES) at the University of Colorado Boulder, has released an updated digital elevation model (DEM) of the U.S. West Coast. This 1 arc-second (~30 m) resolution model spans from 123.25 to 127 W longitude and 37 to 44 N latitude, covering coastal northern California and southern Oregon. This DEM merges bathymetric (seafloor) and topographic (land) data at the coastline to provide a continuous representation of the earth's surface from the deep ocean to the coastal uplands and supports a wide range of coastal and environmental applications including hazard assessment, ecosystem research, and planning efforts in dynamic coastal regions. The DEM was produced through the Continuously-Updated DEM (CUDEM) Program, NOAA's open-source framework for developing elevation models across spatial scales. The CUDEM framework prioritizes transparency, traceability, and accessibility.
