Description:
Abstract:
This Coastal Relief Gridded database provides the first comprehensive view of the US Coastal Zone; one that extends from the coastal state boundaries to as far offshore as the NOS hydrographic data will support a continuous view of the seafloor. In many cases, this seaward limit reaches out to, and in places even beyond the continental slope.
Bathymetric data sources include the US National Ocean Service Hydrographic Database, the US Geological Survey (USGS), Monterey Bay Aquarium Research Institute (MBARI), US Army Corps of Engineers LIDAR (SHOALS), and various other academic institutions. Topographic data are from the USGS 3-arc-second DEMs and Shuttle Radar Topography data (SRTM). Volumes 3 through 5 also use bathymetric contours from the International Bathymetric Chart of the Caribbean Sea and the Gulf of Mexico project as input to the gridding process.
The gridded database contains data for the entire coastal zone of the conterminous US, including Hawaii and Puerto Rico. Gridded data for the Great Lakes, and integrated grids of these and additional U.S. Coastal areas, including Alaska are also available at other resolutions.
Purpose:
See <http://www.ngdc.noaa.gov/mgg/coastal/coastal.html> for more information about the NGDC Coastal Relief Model.

Process_Description:
CZM downloaded the data from the NGDC GEODAS Grid Translator - Design-a-Grid website (<http://www.ngdc.noaa.gov/mgg/gdas/gd_designagrid.html>) on December 16, 2010. The following grid was downloaded:
Grid database: US Coastal Relief Model Grids Grid Area in degrees and minutes: Upper Latitude: 43 0 N Lower Latitude: 40 25 N Left Longitude: 71 30 W Right Longitude: 69 05 W Grid Cell Size: 3 seconds Grid Format: Output Grid Format: ASCII Raster Format Output Grid Header: ASCII (Arc) Header
The ArcGIS ASCII to Raster tool was used to convert the ASCII file to a floating-point raster dataset. The projection of the raster was defined to the North American Datum of 1983. The raster was then projected to the North American Datum of 1983, Massachusetts State Plane Coordinate System, Mainland Zone (FIPS zone 2001), meters. Finally, a con statement was used to turn cells with a value greater than 0 to NoData.
