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 San Francisco Bay/Monterey (CA) WFO DEM was split into three smaller DEMs. They are divided along county lines and are: 1. San Francisco Bay/Monterey (CA) WFO - Santa Cruz and Monterey Counties 2. San Francisco Bay/Monterey (CA) WFO - Contra Costa, San Francisco, Alameda, San Mateo, and Santa Clara Counties 3. 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 - Contra Costa, San Francisco, Alameda, San Mateo, and Santa Clara Counties. The DEM includes the best available lidar data known to exist at the time of DEM creation for the coastal areas of Contra Costa, San Francisco, Alameda, San Mateo, and Santa Clara Counties, that met project specifications. The DEM is derived from LiDAR data collected for the California Coastal Conservancy, NOAA and the United States Geological Survey between 2009 and 2011. Hydrographic breaklines used in the creation of the DEM were obtained from the California Coastal Conservancy, NOAA or the USGS. 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. completed NOAA Office for Coastal Management (843) 740-1202 2234 South Hobson Ave Charleston SC 29405-2413 coastal.info@noaa.gov https://coast.noaa.gov WWW:LINK-1.0-http--link NOAA Office for Coastal Management Website NOAA Office for Coastal Management Home Page information pointOfContact NOAA Office for Coastal Management (843) 740-1202 2234 South Hobson Ave Charleston SC 29405-2413 coastal.info@noaa.gov https://coast.noaa.gov WWW:LINK-1.0-http--link NOAA Office for Coastal Management Website NOAA Office for Coastal Management Home Page information custodian notPlanned EARTH SCIENCE > LAND SURFACE > GEOMORPHIC LANDFORMS/PROCESSES > COASTAL PROCESSES > FLOODING EARTH SCIENCE > LAND SURFACE > GEOMORPHIC LANDFORMS/PROCESSES > COASTAL PROCESSES > SEA LEVEL CHANGES EARTH SCIENCE > LAND SURFACE > TOPOGRAPHY > TERRAIN ELEVATION > DIGITAL ELEVATION/TERRAIN MODEL (DEM) theme Global Change Master Directory (GCMD) Science Keywords 23.3 CONTINENT > NORTH AMERICA > UNITED STATES OF AMERICA > CALIFORNIA place Global Change Master Directory (GCMD) Location Keywords 23.3 Bathymetry/Topography DEM Digital Elevation Model elevation flooding inundation lidar sea level rise topography theme Alameda County California Contra Costa County San Francisco County San Mateo County Santa Clara County US place DOC/NOAA/NOS/OCM > Office of Coastal Management, National Ocean Service, NOAA, U.S. Department of Commerce dataCentre Global Change Master Directory (GCMD) Data Center Keywords 2017-04-24 publication 8.5 Earth Science Data and Information System, Earth Science Projects Division, Goddard Space Flight Center (GSFC), National Aeronautics and Space Administration (NASA) https://forum.earthdata.nasa.gov/app.php/tag/GCMD%2BKeywords GCMD Keyword Forum Page Global Change Master Directory (GCMD). 2026.

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. Ground classified points (Class 2) and those classified as mudflats (Class 10; project specific) 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. 2011-01-01T00:00:00 Source Contribution: Lidar points covering portions of San Francisco, San Mateo, Santa Clara, Alameda, and Contra Costa counties were used in developing the DEM. | Type of Source Media: online digital data NOAA Office for Coastal Management lidar data holdings 2012-01-01 publication NOAA Office for Coastal Management https://coast.noaa.gov/dataviewer/ WWW:LINK-1.0-http--link Source Citation URL Source Citation URL information 2009 2011 Source Contribution: Lidar points covering portions of San Francisco, San Mateo, Santa Clara, Alameda, and Contra Costa counties were used in developing the DEM. | Type of Source Media: online digital data USGS CLICK lidar data holdings 2010-01-01 publication USGS Center for LiDAR Information Coordination and Knowledge http://lidar.cr.usgs.gov/ WWW:LINK-1.0-http--link Source Citation URL Source Citation URL information 2010
