NGDC created the comprehensive data set by merging the U.S. Geological Survey 3-arc-second DEMs with a compilation of hydrographic soundings covering the US East Coast. The Coastal Relief Model extends from the coastal state boundaries to as far offshore as the data will support a continuous view of the seafloor. This dataset formed the basis for the creating of the CRM bathymetry image for this product's GIS. Purpose: This image provides a color view of the CRM for the project area and is used as a basemap for overlaying land loss and shoreline change data.

Process_Step: Process_Description: The desired data was extracted from the Coastal Relief Model volumes 3, 4 and 5 in the ESRI ASCII format. The ASCII dataset was then converted to an ESRI grid file and combined to a single ESRI grid file.
