Chignik, Alaska 1/3 arc-second 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).

Puget Sound, WA (P290) Bathymetric Digital Elevation Model (30 meter resolution) Derived From Source Hydrographic Survey Soundings Collected by NOAA

Bathymetry for Puget Sound was derived from eighty-eight surveys containing 930,967 soundings. There were thirty-nine older, overlapping, less accurate surveys that were either partially or entirely omitted. The average separation between soundings was 53 meters. The surveys used dated from 1934 to 1982 with the majority falling between 1934 and 1943. The total range of soundings for the surveys used was 3.0 to -295.1 meters at mean low water. Mean high water values between 1.5 and 3.4 meters were assigned to the shoreline. Forty 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). Puget Sound has sixty-seven 7.5 minute DEMs and three 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.

St. Helena Sound, SC (S100) Bathymetric Digital Elevation Model (30 meter resolution) Derived From Source Hydrographic Survey Soundings Collected by NOAA

Bathymetry for St. Helena Sound was derived from nineteen surveys containing 83,246 soundings. No surveys were omitted. The average separation between soundings was 49 meters. Sixteen of the nineteen surveys used dated from 1934. The remaining surveys, located in the southwest, dated from 1956 and 1973. The total range of sounding data was 3.7 meters to -23.5 meters at mean low water. Mean high water values between 1.5 and 2.1 meters were assigned to the shoreline. Six 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). St. Helena Sound has eleven 7.5 minute DEMs and a single one degree DEM. 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.

Narragansett Bay, RI (M020) Bathymetric Digital Elevation Model (30 meter resolution) Derived From Source Hydrographic Survey Soundings Collected by NOAA

Bathymetry for Narragansett Bay was derived from fifteen surveys containing 165,184 soundings. Three older, less accurate, overlapping surveys were entirely omitted, and the overlap from six older, less accurate surveys was omitted before tinning the data. The average separation between soundings was 50 meters. The fifteen surveys used dated from 1943 to 1957. The total range of sounding data was 1.2 meters to - 58.8 meters at mean low water. Mean high water values between 0.9 and 1.4 meters were assigned to the shoreline. Four 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). Narragansett Bay has thirteen 7.5 minute DEMs and a single one degree DEM. 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.

Mobile Bay, AL (G150) Bathymetric Digital Elevation Model (30 meter resolution) Derived From Source Hydrographic Survey Soundings Collected by NOAA

Bathymetry for Mobile Bay was derived from twenty-three surveys containing 173,661 soundings. Older, overlapping, less accurate surveys were deleted. The average separation between surveys was 79 meters. The surveys used dated from 1960 to 1962. The range of soundings for the surveys was 0.6 meters to -32.9 meters at mean low water. Mean high water values between 0.3 and 0.5 meters were assigned to the shoreline. Nine 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). Mobile Bay has eighteen 7.5 minute DEMs and two 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.
