Coastal Relief Models (CRMs)

Thumbnail of the CRMs

Coastal Relief Models CRMs provide seamless topographic and bathymetric bare-earth elevation profiles of coastal regions for US states and territories. Extents span from beyond the upper extent of coastal food zones, out to the continental shelf. As of 2023, new CRM releases are being produced at 1-arc-second horizontal resolution in a geographic WGS84 lat-lon grids. The vertical reference system is EGM2008 or Mean Sea Level (Hawaii and Puerto Rico).
