Central Oregon Coastal Digital Elevation Model NAVD 88
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 a vertical tidal datum of Mean High Water (MHW) or NAVD 88
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).

| Processing Steps |
- 2015-08-01T00:00:00 -All datasets obtained by NCEI were converted to common horizontal and vertical datums
of WGS84 geographic and NAVD 88, respectively, using GDAL. They were also converted
to common file format, ESRI point shapefiles, for visualization and inspection.
- 2015-09-01T00:00:00 -Datasets were visually inspected with ArcGIS for identification and editing of data
anomalies. Datasets were then compared with overlapping datasets to ensure data consistency.
- 2015-09-28T00:00:00 -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.
- 2015-10-28T00:00:00 -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.
- 2015-11-28T00:00:00 -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.
- 2015-12-28T00:00:00 -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.
