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).

Pamlico Sound, NC (S020) Bathymetric Digital Elevation Model (30 meter resolution) Derived From Source Hydrographic Survey Soundings Collected by NOAA

Bathymetry for Pamlico Sound was derived from Sixty-five surveys containing 648,402 soundings. Nine older, overlapping, less accurate surveys were entirely omitted before tinning the data. The overlap from eight older, less accurate surveys was omitted prior to tinning. The average separation between soundings was 104 meters. Ten surveys in the southwest dated prior to 1900. The remaining fifty-five surveys used dated from 1913 to 1980. The total range of sounding data was 0.3 meters to -21 meters at mean low water. Mean high water values between 0.1 and 0.6 meters were assigned to the shoreline. Twelve points were found that were not consistent with the surrounding data. These were removed prior to tinning. DEM grid values outside the shoreline (on land) were assigned null values (-32676). Update 2 (10/31/00): Seven additional surveys collected prior to 1900 have been digitized and have been included in the new update. These surveys were in the Pamlico River and at the mouth of the Neuse River, as well as the Wysocking Bay region. The previous update corrected an error in one of the hydro-graphic surveys where feet were registered as fathoms. These soundings were near the mouth of the estuary. No soundings of greater than 21 meters should be present within Pamlico Sound. A vector file delineating the regions were data are inadequate for quality 30m bathymetry have been included in the Zipped files in both Mapinfo [MIF] and ArcView [SHP] formats. NOTE: These updated DEMs are NOT available for the 3 arc second version. Pamlico Sound has seventy-eight 7.5 minute DEMs and four one degree DEMs. The 1 degree DEMs were generated from the higher resolution 7.5 minute DEMs which covered the estuary. A Digital Elevation Model (DEM) contains a series of elevations ordered from south to north with the order of the columns from west to east. The DEM is formatted as one ASCII header record (A- record), followed by a series of profile records (B- records) each of which include a short B-record header followed by a series of ASCII integer elevations (typically in units of 1 centimeter) per each profile. The last physical record of the DEM is an accuracy record (C-record). The 7.5-minute DEM (30- by 30-m data spacing) is cast on the Universal Transverse Mercator (UTM) projection. It provides coverage in 7.5- by 7.5-minute blocks. Each product provides the same coverage as a standard USGS 7.5-minute quadrangle but the DEM contains over edge data. Coverage is available for many estuaries of the contiguous United States but is not complete.

EMAG2: Earth Magnetic Anomaly Grid (2-arc-minute resolution)

EMAG2 is a global Earth Magnetic Anomaly Grid compiled from satellite, ship, and airborne magnetic measurements.  It is a significant update of our previous candidate grid for the World Digital Magnetic Anomaly Map. The resolution has been improved from 3 arc-minutes to 2 arc-minutes, and the altitude has been reduced from 5 km to 4 km above the geoid. Additional grid and track line data have been included, both over land and the oceans. Wherever available, the original shipborne and airborne data were used instead of precompiled oceanic magnetic grids. Interpolation between sparse track lines in the oceans was improved by directional gridding and extrapolation, based on oceanic crustal age model. The longest wavelengths (>330 km) were replaced with the latests CHAMP satellite magnetic field model MF6.

Atlantic City, New Jersey Tsunami Forecast Grids for MOST Model

The Atlantic City, New Jersey Forecast Model Grids provides bathymetric data strictly for tsunami inundation modeling with the Method of Splitting Tsunami (MOST) model. MOST is a suite of numerical simulation codes capable of simulating three processes of tsunami evolution: generation, transoceanic propagation, and inundation of dry land. Tsunami waves are computationally propagated across a set of three nested grids (A, B, and C), each of which is successively finer in resolution, moving from offshore to onshore. Nearshore details are resolved to the point that model output can be directly compared with tide gauge observations and can provide estimates of wave arrival time, wave amplitude and simulation of wave inundation onto dry land. A Grid Resolution: 30 arc-sec. B Grid Resolution: 6 arc-sec. C Grid Resolution: 2 arc-sec.

Gravity Data for the Greater Portland Area

The gravity station data (1,522 records) were compiled by the Portland State University. This data base was received in August 1990. Principal gravity parameters include Free-air Anomalies and Complete Bouguer Anomalies (terrain correction applied). The observed gravity values are referenced to the International Gravity Standardization Net 1971 (IGSN 71). The gravity anomaly computation uses the Geodetic Reference System 1967 (GRS 67) theoretical gravity formula. The data are randomly distributed within the boundaries of the greater Portland area.

Northern Mariana Islands: Continuously Updated Digital Elevation Model (CUDEM) - 1/3 Arc-Second Resolution Bathymetric-Topographic Tiles

NOAA's National Centers for Environmental Information (NCEI) is developing a suite of digital elevation models (DEMs) for the U.S. coast to support a variety of NOAA missions, including improved inundation modeling and mapping, habitat characterization, and visualization of Earth's surface. The DEMs are being developed according to a 0.25 degree tiling scheme. The spatial resolution of the tiles "telescopes" from the coastal zone to the deep ocean floor at 1/9, 1/3, and 3 arc-second grid resolution. Only the 1/9 arc-second DEM tiles integrate both bathymetric and topographic data; all other resolutions map bathymetry only. The tiling of the DEMs facilitates targeted, rapid updates as new coastal and marine elevation data are acquired and become available. Bathymetric and topographic data utilized for DEM creation originate from a variety of sources, including (but not limited to) the NOAA Office of Coast Survey, NOAA National Geodetic Survey, NOAA Office for Coastal Management, U.S. Geological Survey, and the U.S. Army Corps of Engineers. The DEMs are referenced vertically to Northern Marianas Vertical Datum of 2003 height (m) . The vertical units of the DEMs are meters. The DEMs are referenced horizontally to NAD 83. The horizontal units of the data are decimal degrees.

ETOPO1 1 Arc-Minute Global Relief Model

In August 2008, the National Geophysical Data Center (NGDC), an office of the National Oceanic and Atmospheric Administration (NOAA), developed the ETOPO1 Global Relief Model as an improvement to the ETOPO2v2 Global Relief Model. ETOPO1 is available in "Ice Surface" (top of Antarctic and Greenland ice sheets) and "Bedrock" (base of the ice sheets) versions. Both versions of ETOPO1 were generated from diverse global and regional digital data sets, which were shifted to common horizontal and vertical datums, and then evaluated and edited as needed. Bathymetric, topographic, and shoreline data used in ETOPO1 were obtained from NGDC, Antarctic Digital Database (ADD), European Ice Sheet Modeling Initiative (EISMINT), Scientific Committee on Antarctic Research (SCAR), Japan Oceanographic Data Center (JODC), Caspian Environment Programme (CEP), Mediterranean Science Commission (CIESM), National Aeronautics and Space Administration (NASA), National Snow and Ice Data Center (NSIDC), Scripps Institute of Oceanography (SIO), and Leibniz Institute for Baltic Sea Research (LIBSR). ETOPO1 is vertically referenced to sea level, and horizontally referenced to the World Geodetic System of 1984 (WGS 84). Cell size for ETOPO1 is 1 arc-minute.
