Puget Sound 1/3 arc-second NAVD 88 Coastal Digital Elevation Model
Thumbnail of DEM
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: NOAA; the U.S. Geological Survey (USGS);
the Puget Sound Lidar Consortium (PSLC); and other federal, state, and local government
agencies, academic institutions, and private companies. DEMs are referenced to the
vertical datum of NAVD 88 and horizontal datum of World Geodetic System 1984 geographic
(WGS 84). Grid spacing for the DEM is 1/3 arc-second (~10 meters).

Processing Steps |
- 2014-04-09T00:00:00 -All datasets obtained by NGDC were converted to common horizontal and vertical datums
of WGS 84 geographic and NAVD 88, respectively, using VDatum. They were also converted
to common file format for visualization and inspection.
- 2014-04-23T00:00:00 -Datasets were visually inspected with ArcGIS for identification and editing of data
anomalies. Datasets were then compared with overlapping datasets to ensure data consistency.
- 2014-05-13T00:00:00 -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
5 meters along the coastline were also included to ensure that the bathymetric grid
reached zero at the coast. The resulting Arc UTF-8 grid was imported into ArcGIS and
clipped to the coastline to remove values over land.
- 2014-05-20T00:00:00 -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.
- 2014-06-10T00:00:00 -The DEM was quantitatively evaluated by comparing with source datasets.
