In early 2014, topographic LiDAR was collected for the entire state of Delaware through a collaboration between the USGS, Delaware Geological Survey (DGS), Department of Natural Resources and Environmental Control (DNREC), and Delaware Department of Transportation (DelDOT), funded through the Hurricane Sandy Supplemental Fund. The state-wide LiDAR data has a RMSEz of 6.3 cm in open terrain. From these data, a seamless, statewide 1-meter, hydro-flattened, bare earth digital elevation model (DEM) was produced. This topographic DEM was used to develop new bathtub-model coastal inundation maps for the state of Delaware. Inundation maps correspond to inundatation scenarios and 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 and advise long-range planning of infrastructure, facilities, land management, land use, and capital spending.

The DGS is, by statute, the state agency responsible for entering into agreements with its counterpart federal agencies, including the U.S. Geological Survey, the USGS Office of Minerals Information (formerly the U.S. Bureau of Mines), and the Bureau of Ocean Energy Management, Regulation and Enforcement (formerly the U. S. Minerals Management Service), and for administering all cooperative programs of the State with these agencies. The DGS also works with many in-state and out-of-state partner agencies and organizations.
