These categorical raster files map 2015 substrate and vegetation characteristics in 5-m cells. The supervised classification raster (FI15_SupClas.tif) depicts landcover attributes (for example, marsh, sand, water, herbaceous vegetation). It was created with a supervised classification of 2015 aerial imagery. Raster files FI15_SubType.tif, FI15_VegDen.tif, FI15_VegType.tif were reclassified from the supervised classification raster with some manual modifications. FI15_SubType.tif maps discrete substrate types; FI15_VegDen.tif maps discrete categories of vegetation density; FI15_VegType.tif maps discrete vegetation types. Raster file FI15_GeoSet.tif maps discrete geomorphic settings (e.g. beach, dunes, washovers) and was digitized manually with reference to source datasets. 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 (Zeigler and others 2019).
