NOAA Office for Coastal Management Coastal Inundation Digital Elevation Model: Melbourne (FL) WFO - Indian River, St. Lucie, and Martin Counties

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 Melbourne (FL) WFO DEM was split into two smaller DEMs. They are divided along county lines and are: 1. Melbourne (FL) WFO - Brevard and Volusia Counties 2. Melbourne (FL) WFO - Indian River, St. Lucie, and Martin Counties This metadata record describes the DEM for Miami (FL) WFO - Indian River, St. Lucie, and Martin Counties. The DEM includes the best available lidar data known to exist at the time of DEM creation for the coastal areas of Indian River, St. Lucie, and Martin counties, that met project specifications. The DEM is derived from LiDAR datasets collected for the Florida Department of Emergency Management (FDEM). LiDAR data for Indian River, St. Lucie and Martin counties was collected in 2007. Hydrographic breaklines used in the creation of the DEM were obtained from FDEM. 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.
