Count Component Title Abstract
1 Central Oregon 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 tsunami forecasting and warning efforts at the NOAA Center for Tsunami Research, Pacific Marine Environmental Laboratory (PMEL). The DEMs are part of the tsunami forecast system SIFT (Short-term Inundation Forecasting for Tsunamis) currently being developed by PMEL for the NOAA Tsunami Warning Centers, and are used in the MOST (Method of Splitting Tsunami) model developed by PMEL to simulate tsunami generation, propagation, and inundation. 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 the vertical tidal datum of Mean High Water (MHW) and horizontal datum of World Geodetic System 1984 (WGS84). Grid spacings for the DEMs range from 1/3 arc-second (~10 meters) to 3 arc-seconds (~90 meters).

            1 2008-06-25T00:00:00 All datasets obtained by NGDC were converted to common horizontal and vertical datums of WGS84 geographic and Mean 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 2008-07-07T00:00:00 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 2008-08-04T00:00:00 Multibeam surveys were gridded to 1/3 arc-second spacing (~10 meters) using MB-System's 'mbgrid' tool. The resulting Arc ASCII grid was imported into ArcGIS.
            1 2008-08-13T00:00:00 xyz files of the bathymetric data were surfaced using GMT's 'surface' tool onto a 1 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 2008-08-25T00:00:00 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 2008-08-28T00:00:00 The DEM was quantitatively evaluated by comparing with source datasets and with elevation values extracted from NGS geodetic monuments. 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.
