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. 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. All DEMs for the entire study area (WFO) were loaded into Global Mapper for a final review. Corrections were applied to the DEM and reprocessed for further review. The DEM was reviewed in Global Mapper for incorrect elevations and artifacts introduced from source inputs or during the raster creation process. img file format) with a cell size of 3 meters.
The ESRI Terrain was converted to a DEM (Erdas Imagine. An ESRI Terrain was then generated from these source data. Hydrographic features were assigned elevation values at or below 0 meters. Ground classified points (Class 2) and those classified as mudflats (Class 10 project specific to CCC data) were used to reflect a bare earth surface. Lidar source data and hydrographic breaklines were obtained and imported into an ESRI ArcGIS file geodatabase for each constituent county within the WFO boundary.

Geographic_Coordinate_Units: Decimal degrees Further information regarding the lidar data can be accessed using the following url's: USGS CLICK: The data used to construct this DEM are publicly available via the NOAA Office for Coastal Management's Digital Coast (or through the USGS CLICK. 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. 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.
The resolution of the DEM is approximately 5 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 DEMs are hydro flattened such that water elevations are less than or equal to 0 meters. Hydrographic breaklines used in the creation of the DEM were obtained from the California Coastal Conservancy, NOAA or the USGS. The DEM is derived from LiDAR data collected for the California Coastal Conservancy, NOAA and the United States Geological Survey between 20. The DEM includes the best available lidar data known to exist at the time of DEM creation for the coastal areas of Santa Cruz and Monterey counties, that met project specifications.
San Francisco Bay/Monterey (CA) WFO - Sonoma, Marin, Napa, and Solano Counties This metadata record describes the DEM for the San Francisco Bay/Monterey (CA) WFO - Santa Cruz and Monterey Counties. San Francisco Bay/Monterey (CA) WFO - Contra Costa, San Francisco, Alameda, San Mateo, and Santa Clara Counties 3. San Francisco Bay/Monterey (CA) WFO - Santa Cruz and Monterey Counties 2. They are divided along county lines and are: 1. The San Francisco Bay/Monterey (CA) WFO DEM was split into three smaller DEMs. Because the WFO boundaries can cover large areas, the WFO DEM was divided into smaller DEMs to ensure more manageable file sizes. The DEMs created for this project were developed using the NOAA National Weather Service's Weather Forecast Office (WFO) boundaries.
