Adjusted digital elevation models (DEMs) for the Apalachee Bay region of the Florida panhandle, representative of 2018-03-01 conditions (NCEI Accession 0256313)

These elevation data (in meters) in Apalachee Bay, Florida, have been systematically and variably lowered, mitigating the bias in the lidar DEM and improving its spot elevation accuracy by approximately 69% in Apalachee Bay, Florida. These data span the big bend region of Florida’s gulf coast consisting of Gulf, Franklin, Wakulla, Jefferson, and Taylor counties. The data are in GIS raster format. These adjusted data are now suitable for modeling salt marsh evolution and flood inundation under sea-level rise (SLR) scenarios. Lidar data used in this adjustment were collected on March 01, 2018.
