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 DEM includes best available lidar data known to exist at the time of DEM creation that meets project specifications for those counties in the state of Washington that fall within the boundary of the Portland, OR Weather Forecast Office (WFO), as defined by the NOAA National Weather Service. The DEM is derived from multiple LiDAR datasets collected between 2002 and 2010 for NOAA, the United States Army Corps of Engineers (USACE) and the United States Geological Survey (USGS). The extent of the DEM includes portions of Pacific, Wahkiakum, Cowlitz, Clark and Skamania counties. Hydrographic breaklines used in the creation of the DEM were either delineated using LiDAR intensity imagery or obtained from USACE. 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.
The NOAA Office for Coastal Management 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.
Acknowledgment of the NOAA Office for Coastal Management 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.

dataset
Horizontal Positional Accuracy
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
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.
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.
Conceptual Consistency
Data covers the project area, defined as the WFO boundary. Elevation data checked for anomalous elevation values outside expected range.
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.
