Count Component Title Abstract
1 San Juan Islands, Washington Coastal Digital Elevation Model NOAA's National Geophysical Data Center (NGDC) is building high-resolution digital elevation models (DEMs) for select U.S. coastal regions. These integrated bathymetric-topographic DEMs are used to support individual coastal States as part of the National Tsunami Hazard Mitigation Program's (NTHMP) efforts to improve community preparedness and hazard mitigation. Bathymetric, topographic, and shoreline data used in DEM compilation are obtained from various sources including: NGDC; the U.S. Geological Survey (USGS); Naval Oceanographic Office (NAVOCEANO); NOAA's Coastal Service Center; and other federal, state, and local government agencies, academic institutions, and private companies. The DEM is referenced to the vertical tidal datum of Mean High Water (MHW).

They were also converted to common file format, ESRI point shapefiles or digital rasters, for visualization and inspection.
              1 2010-08-15T00:00:00 Datasets were visually inspected with ArcGIS and QT Modeler for identification and editing of data anomalies. Datasets were then compared with overlapping datasets to ensure data consistency.
              1 2010-11-15T00:00:00 xyz files of the bathymetric data were surfaced using GMT's 'surface' tool onto a 1/3 arc-second grid that interpolated to fill empty cells. Points extracted every 10 meters along the coastline were also included to ensure that the bathymetric grid reached zero at the coast. The resulting Arc ASCII grid was imported into ArcGIS and clipped to the coastline to remove values over land.
              1 2010-12-20T00:00:00 xyz files for each input dataset were gridded using MB-System's 'mbgrid' tool, which utilizes a high-tension spline interpolation method to fill grid cells with no input elevation values. Preferential weighting was given to more recent, higher-accuracy datasets. Gridding was performed in quadrants, each with a 5% data buffer. The grids were imported in ArcGIS and seamlessly merged to create the final DEM.
              1 2011-01-20T00:00:00 The DEM was quantitatively evaluated by converting to UTM-zone coordinates (units of meters horizontally and vertically) and then creating a slope grid to identify gridding artifacts in the DEM. A conversion grid was created using VDatum points to convert the NAVD 88 San Juan Islands DEM to MHW.
              1 2015-04-22T00:00:00 NOAA created the National Centers for Environmental Information (NCEI) by merging NOAA's National Climatic Data Center (NCDC), National Geophysical Data Center (NGDC), and National Oceanographic Data Center (NODC), including the National Coastal Data Development Center (NCDDC), per the Consolidated and Further Continuing Appropriations Act, 2015, Public Law 113-235. NCEI launched publicly on April 22, 2015.
