  Description:
    Abstract:
      This digital elevation model (DEM) is a part of a series of DEMs produced for the National Oceanic and Atmospheric Administration Coastal
      Services Center's Sea Level Rise and Coastal Flooding Impacts Viewer. The DEMs created for this project were developed using the NOAA
      National Weather Service's Weather Forecast Office (WFO) boundaries. Because the WFO boundaries can cover large areas, the WFO DEM was divided 
      into smaller DEMs to ensure more manageable file sizes. 

      The Seattle (WA) WFO DEM was split into three smaller DEMs. They are divided along county lines and are:
      1. Seattle (WA) WFO - Grays Harbor County
      2. Seattle (WA) WFO - Clallam, Jefferson, Kitsap, Mason, Pierce, and Thurston Counties
      3. Seattle (WA) WFO - Whatcom, San Juan, Skagit, Island, Snohomish, and King Counties

      This metadata record describes the DEM for Seattle (WA) WFO - Grays Harbor County. The DEM includes the best available lidar data known to exist
      at the time of DEM creation for the coastal areas of Grays Harbor County, that met project specifications.

      The DEM is derived from LiDAR datasets collected for the Puget Sound LiDAR Consortium (PSLC), United States Geological Survey (USGS) and the Oregon
      Department of Geology and Mineral Industries (DOGAMI), available from the NOAA Digital Coast. Hydrographic breaklines used in the creation of
      the DEM were delineated using LiDAR intensity imagery generated from each constituent dataset. The DEMs are hydro flattened such that water 
      elevations are less than or equal to 0 meters.

      The DEM is referenced vertically to the North American Vertical Datum of 1988 (NAVD88) with vertical units of meters and horizontally to
      the North American Datum of 1983 (NAD83). The resolution of the DEM is approximately 5 meters.

    Purpose:
      The NOAA Coastal Services Center has developed high-resolution digital elevation models (DEMs) for use in the Center's Sea Level Rise And
      Coastal Flooding Impacts internet mapping application. These DEMs serve as source datasets used to derive data to visualize the impacts of
      inundation resulting from sea level rise along the coastal United States and its territories.

  Use_Constraints:
    The dataset is provided "as is," without warranty to its performance, merchantable state, or fitness for any particular purpose. The entire
    risk associated with the results and performance of this dataset is assumed by the user. This dataset should be used strictly as a
    planning reference and not for navigation, permitting, or other legal purposes.

  Data_Set_Credit:
    Acknowledgment of the NOAA Coastal Services Center as a data source would be appreciated in products developed from these data, and such
    acknowledgment as is standard for citation and legal practices for data source is expected.

Data_Quality_Information:
  Logical_Consistency_Report: Data covers the project area, defined as the WFO boundary. Elevation data checked for anomalous elevation
    values outside expected range.

  Completeness_Report: 
    A visual qualitative check was performed to ensure data completeness. All available lidar data known at the time of DEM creation that meets
    project specifications has been used to develop the DEM. Known data gaps may exist where lidar coverage was incomplete.

  Positional_Accuracy:
    Horizontal_Positional_Accuracy:
      Horizontal_Positional_Accuracy_Report: 
        The DEM is derived from the source lidar data. Horizontal accuracy testing is not performed on the DEM. Lidar source data assumed to
        meet 1 meter horizontal accuracy.

    Vertical_Positional_Accuracy:
      Vertical_Positional_Accuracy_Report: 
        The DEM is derived from the source lidar data. Vertical accuracy is not tested on the DEM. Project specifications require all source
        lidar data used in constructing the DEM to meet FEMA Specifications for Flood Hazard Mapping.

    Process_Step:
      Process_Description:
        1. Lidar source data and hydrographic breaklines were obtained and imported into an ESRI ArcGIS file geodatabase for each constituent county
           within the WFO boundary. Only ground classified lidar (Class 2) points were used to reflect a bare earth surface. Hydrographic features
           were assigned elevation values at or below 0 meters. An ESRI Terrain was then generated from these source data.
        2. The ESRI Terrain was converted to a DEM (Erdas Imagine .img file format) with a cell size of 3 meters. The DEM was reviewed in Global
           Mapper for incorrect elevations and artifacts introduced from source inputs or during the raster creation process. Corrections were applied
           to the DEM and reprocessed for further review.
        3. All DEMs for the entire study area (WFO) were loaded into Global Mapper for a final review. The constituent DEMs were then checked to
           ensure complete coverage within the study area and that no issues existed along the boundary between adjacent DEMs. Once it was determined all
           DEMs were seamlessly edge-matched and no other artifacts were present, the constituent DEMs were mosaiced together, resampled to 5m
           and reprojected to the NAD83 geographic coordinate system.
