These data provide samples of barrier island characteristics for use in Bayesian networks to model geomorphology and shorebird nesting habitat condition and change. Transects spaced every 50 m alongshore from the National Assessment of Shoreline Change (NASC; smi_trans.shp) were extended and supplemented to use as the base sampling unit to compile and sample barrier island characteristics. Attributes are provided at 5-m sample points (smi14_pts.csv) along each transect and include both values extracted for the entire transect and values extracted at each point. The attributes in the points file can be aggregated by transect and joined to the transect features by the field sort_ID. The beach width values calculated for each transect are also provided as a spatially continuous raster (smi14_ubw.tif). See Zeigler and others (2019) for additional details.
