This digital elevation model (DEM) is a part of a series of DEMs produced for the National Oceanic and Atmospheric Administration Office for Coastal Management'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 - Clallam, Jefferson, Kitsap, Mason, Pierce, and Thurston Counties. The DEM includes the best available lidar data known to exist at the time of DEM creation for the coastal areas of Clallam, Jefferson, Kitsap, Mason, Pierce, and Thurston counties, that met project specifications. The DEM is derived from multiple LiDAR datasets collected between 1996 and 2005 for the Puget Sound LiDAR Consortium. 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.
