U.S. Interagency Elevation Inventory

The U.S. Interagency Elevation Inventory provides a comprehensive listing of known high-accuracy topographic and bathymetric data for the U.S. and its territories. Elevation data is necessary to develop coastal elevation models and are critical components when looking at sea level rise, coastal flooding, beach nourishment, erosion, or any other processes that occur within the land-water interface.
