Area inundated after 1 - m rise in sea level
The sea level rise (SLR) scenario represented by this GIS polygon was created by the Skidaway Institute of Oceanography to demonstrate the potential area of inundation with a 1 meter rise in the Mean Higher High Water (MHHW) surface.  The 1 meter SLR values were generated based on a water level rise above the current Mean Higher High Water (MHHW) surface estimated for each Coastal GA county.  Base elevation data used for the scenario is a 4ft by 4ft cell resolution liDAR derived hydro enforced digital elevation model (DEM) created by the Georgia Coastal Elevation Project.  Areas of the DEM lower than the 1m SLR scenario surface were removed unless connected to tidal waters.
