NOAA Office for Coastal Management Coastal Inundation Digital Elevation Model: Aggregate Record

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. This metadata record describes the aggregate DEM and WFO specific metadata exists for each WFO. The DEM includes the best available lidar data known to exist at the time of DEM creation for each WFO. 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, though some areas may have higher resolution.
