Service Description: LiDAR based 1-m DEM was used to develop new bathtub-model coastal inundation maps for the state of Delaware. Inundation maps include surfaces from Mean Higher-High Water (MHHW) to 7 feet above MHHW, in 1-foot increments. These maps will help assess the potential impacts of sea-level rise, storm surges, and numerous other applications and will advise long-range planning of infrastructure, facilities, land management, land use, and capital spending.
