Description:
Abstract:
Investigations of coastal change and coastal resources often require continuous elevation profiles from the seafloor to coastal terrestrial landscapes. Differences in elevation data collection in the terrestrial and marine environments result in separate elevation products that may not share a vertical datum. This data release contains the assimilation of multiple elevation products into a continuous digital elevation model at a resolution of 3-arcseconds (approximately 90 meters) from the terrestrial landscape to the seafloor for the contiguous U.S., focused on the coastal interface. All datasets were converted to a consistent horizontal datum, the North American Datum of 1983, but the native vertical datum for each dataset was not adjusted. Artifacts in the source elevation products were replaced with other available elevation products when possible, corrected using various spatial tools, or otherwise marked for future correction. This data release contains the assimilation of multiple elevation products into a continuous digital elevation model at a resolution of 3-arcseconds (approximately 90 meters) from the terrestrial landscape to the seafloor for the contiguous U.S. that were constructed using this shapefile.
Purpose:
The purpose of this dataset is to identify and correct elevation artifacts in the source elevation datasets that can be corrected in future products or were corrected. These artifacts are assigned a Type and Action attribute that is used to correct the source datasets where possible using the processing steps for creating the west_cdem_v1.tif and east_cdem_v1.tif rasters. The primary focus of the artifact delineation was between -50 to 50 meters elevation. Only those interpolation artifacts that could be replaced by other data, were unavoidable/unfillable using other datasets, or were distinguishable from nearby bathymetry or topography were delineated and saved in DEM_artifacts.shp.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
Features were manually drawn. Many of the artifacts were lines (i.e., infinitely thin) that were delineated by polygonal features with a finite width. The drawn width does not represent an area for the artifact, but rather outlines the general location of the artifact.
Logical_Consistency_Report:
The individual and merged elevation datasets were checked for accuracy in the coastal area using coloring schemes that highlighted elevations near sea level (e.g., -10 m to 10 m). These areas were delineated manually and at multiple scales. Features contained in this dataset do not locate all elevation artifacts.
Completeness_Report:
Data set is considered complete for the information presented, as described in the abstract. Users are advised to read the rest of the metadata record carefully for additional details.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
The horizontal accuracy of the features were dependent upon the horizontal accuracy of the source terrain models. The feature boundary locations were manually drawn and do not represent an exact position or boundaries of an artifact, but instead were meant to indicate the presence of an artifact within the area encompassed by the polygon feature.
Vertical_Positional_Accuracy:
Vertical_Positional_Accuracy_Report: The shapfile has no vertical component.

Elevations greater than 8 meters in the final product are all from NED data. Elevations between 8 and 0 meters may be NED values but the source depends on the availability of bathymetry for each grid cell.

This dataset was used to supply values where the merged CRM and NED datasets were missing bathymetry values.
Process_Step:
Process_Description:
Manually outlined and delineated features where the DEMs in this analysis required additional steps to correct artifacts using ArcGIS 10.3. The elevations were checked primarily by using a color scheme that ranged from slightly below sea level to slightly above sea level to accentuate the elevations in the coastal zones. For the U.S. east coast, the range used was primarily -10 m to 10 m relative to zero in the datum of the source data. For the U.S. west coast, -20 m to 20 m and -10 m to 50 m were used to check both coastal zones and as well as deeply incised channels.
