Count Component Title Abstract
1 Prince William Sound, Alaska 8 Arc-second MHHW Coastal Digital Elevation Model NOAA's National Geophysical Data Center (NGDC) is building high-resolution digital elevation models (DEMs) to support individual coastal States as part of the National Tsunami Hazard Mitigation Program's (NTHMP) efforts to improve community preparedness and hazard mitigation. These integrated bathymetric-topographic DEMs are used to support tsunami and coastal inundation mapping. Bathymetric, topographic, and shoreline data used in DEM compilation are obtained from various sources, including NGDC, the U.S. National Ocean Service (NOS), the U.S. Geological Survey (USGS), the U.S. Army Corps of Engineers (USACE), the Federal Emergency Management Agency (FEMA), and other federal, state, and local government agencies, academic institutions, and private companies. DEMs are referenced to various vertical and horizontal datums depending on the specific modeling requirements of each State. For specific datum information on each DEM, refer to the appropriate DEM documentation. Cell sizes also vary depending on the specification required by modelers in each State, but typically range from 8/15 arc-second (~16 meters) to 8 arc-seconds (~240 meters).

            1 2009-01-15T00:00:00 All datasets obtained by NGDC were converted to common horizontal and vertical datums of WGS84 geographic and Mean Higher High Water, respectively, using FME. They were also converted to common file format, ESRI point shapefiles, for visualization and inspection.
            Barry Eakins at Xpath: /gmi:MI_Metadata/gmd:dataQualityInfo[2]/gmd:DQ_DataQuality[1]/gmd:lineage[1]/gmd:LI_Lineage[1]/gmd:processStep[1]/gmi:LE_ProcessStep[1]/gmd:processor[1]
            1 2009-01-29T00:00:00 Datasets were visually inspected with ArcGIS for identification and editing of data anomalies. Datasets were then compared with overlapping datasets to ensure data consistency.
            1 2009-02-12T00:00:00 xyz files of the bathymetric data were surfaced using GMT's 'surface' tool onto a 8/3 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 2009-02-26T00:00:00 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 with a 5% data buffer. The grid was imported in ArcGIS to create the final DEM.
            1 2009-03-12T00:00:00 The DEM was quantitatively evaluated by comparing with source datasets. It was visually 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.
