This digital elevation model (DEM) represents the elevation (adjusted for mean high water tidal datum) for each 5x5 m cell within the boundaries of the Ship Shoal Island, Virginia study area as measured by lidar collected in 2014. See Zeigler and others (2019) for additional details.
The DEM is part of a series of spatial datasets used to describe characteristics of barrier islands found along the North American Atlantic coast in order to identify habitat for the federally protected piping plover (Charadrius melodus). Information contained in these spatial datasets was used within a Bayesian network to model the probability that a specific set of landscape characteristics would be associated with piping plover habitat.
