Coastal Relief Model
NCEI's U.S. Coastal Relief Model (CRM) integrates offshore bathymetry with land topography into a seamless representation of the coast. The CRM spans the U.S. East and West Coasts, the northern coast of the Gulf of Mexico, Puerto Rico, and Hawaii,
reaching out to and beyond the continental slope.
Bathymetric data sources include the U.S. National Ocean Service
Hydrographic Database, the U.S. Geological Survey (USGS), the Monterey Bay Aquarium Research Institute, the U.S. Army Corps of Engineers, and other academic institutions. Topographic data are from the USGS and the Shuttle Radar Topography Mission. Volumes 3-5 use bathymetric contours from the International Bathymetric Chart of the Caribbean Sea and the Gulf of
Mexico project.
The CRM contains grids, or digital elevation models (DEMs), of the U.S. coastal zone. Bathymetry of the
Great Lakes and more detailed DEMs of
U.S. coastal areas, are also available.
How to Cite: Each volume is uniquely cited. See below (name) for details.
