Given this increasing need to forecast sea-level rise effects on barrier islands in the near and long terms, we are developing Bayesian networks to evaluate and to forecast the cascading effects of sea-level rise on shoreline change, barrier island state, and piping plover habitat availability. We use publicly available data products, such as lidar, orthophotography, and geomorphic feature sets derived from those, to extract metrics of barrier island characteristics at consistent sampling distances. The metrics are then incorporated into predictive models and the training data used to parameterize those models. This data release contains the extracted metrics of barrier island geomorphology and spatial data layers of habitat characteristics that are input to Bayesian networks for piping plover habitat availability and barrier island geomorphology. These datasets and models are being developed for sites along the northeastern coast of the United States. This work is one component of a larger research and management program that seeks to understand and sustain the ecological value, ecosystem services, and habitat suitability of beaches in the face of storm impacts, climate change, and sea-level rise. Purpose: The distance to foraging layer (Assa14_DisMOSH.tif) identifies the least-cost path distance for a piping plover chick to travel from the center of each 5x5 m grid cell to low-energy foraging areas with moist substrates. The distance to foraging data were used within a Bayesian network to model the probability that a specific set of landscape characteristics would be associated with piping plover habitat. The movement cost layer (Assa14_Cost.tif) identifies barriers to the movement of piping plover chicks, with barriers including water, human development, and moderate to dense vegetation. Barriers were identified using orthoimagery captured in 2014 (see data sources below). The movement cost layer was used to calculate the least-cost path distance (Assa14_DisMOSH.tif) to the nearest foraging area (Assa14_MOSH_Shoreline.shp). The foraging shorelines shapefile (Assa14_MOSH_Shoreline.shp) delineates foraging shorelines with moist substrates for piping plovers. Foraging areas were determined from elevations measured in 2014 and orthoimagery captured in 2014. Here, foraging shorelines are defined as low-energy and could include the shorelines of sound- or bay-side beaches, interior ponds, and ephemeral pools. Ocean shorelines were not considered low-energy foraging shorelines. See Zeigler and others (2019) for additional details.

Online_Linkage: https://doi.org/10.3133/ofr20191071 Data_Quality_Information: Logical_Consistency_Report: These files consist of polyline and raster data produced from aerial imagery and a digital elevation model (DEM) through a semi-automated process described below. The foraging shoreline file consists of a polyline vector dataset manually clipped from the shoreline polygon(s) in the larger work (assa14_shoreline.shp). The full shoreline was QA/QC'd in ArcMap. No further logical accuracy tests were conducted on the present dataset. Completeness_Report: These datasets are clipped to a custom boundary and may not include the entire spatial extent of the original source datasets as they are published in original form. However, the custom boundary spans the entire coverage of the Assawoman Island site relevant to the broader research program (see Zeigler and others, 2019 for more details). The movement barriers are derived from a combination of four layers released in the larger work (see process description below) and are a complete combination of the inputs. This dataset is considered complete for the information presented as described in the abstract section. Users are advised to read the rest of the metadata record carefully for additional details. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: All datasets inherit the horizontal accuracy of the source data from which they were created. The movement cost layer (Assa14_Cost.tif) was produced using categorical landcover maps published in the larger work (Assa14_GeoSet.tif, Assa14_VegType.tif, Assa14_VegDen.tif, Assa14_VegDen.tif). We estimate that all four source landcover layers, and therefore the movement cost layer, are accurate within 5 m. The foraging shoreline layer (Assa14_MOSH_Shoreline.shp) was created from the shoreline file in the larger work and the orthoimage, and inherits the horizontal accuracy of these layers. We estimate the accuracy to be within 25 m horizontally. The distance to foraging dataset (Assa14_DisMOSH.tif) was created directly from the foraging shoreline and movement cost layer (Assa14_MOSH_Shoreline.shp and Assa14_Cost.tif). We estimate the accuracy of the distance to foraging dataset within 5 m horizontally. No further formal accuracy assessments of the horizontal positional information in these datasets have been conducted.

Source data were distributed at 0.35 m pixel resolution, in horizontal datum NAD83. Downloaded on 2/21/2017. Data were projected to UTM Zone 18N (EPSG:26918) using the ‘Project Raster’ tool in ArcToolbox (version 10.4.1). Process_Step: Process_Description: Assa14_MOSH_Shoreline.shp This vector file delineates foraging shorelines with moist substrates for piping plovers and their chicks. These are areas where piping plovers and their chicks could forage for terrestrial arthropods, invertebrates, marine worms, and other foods. Foraging shorelines are defined as low-energy and could include the shorelines of sound- or bay-side beaches, interior ponds, and ephemeral pools. Ocean shorelines are not considered low-energy foraging shorelines. Full methods are provided in the associated Open-File Report (Zeigler and others, 2019). All processing was performed in ArcGIS version 10.4.1. We converted the shoreline polygon file (assa14_shoreline.shp in larger work) to polyline format using the 'Polygon to Line' tool in ArcGIS. We overlaid the output shoreline polylines on the orthoimage and - in an Edit session - manually removed sections of the lines that did not correspond to inlets, ponds, ephemeral water bodies, or back-barrier sandy beaches. This included removing the ocean-facing shoreline. These features were identified based on visual inspection of the orthoimage. Also during this Edit session, we hand-digitized the boundaries of low-energy shorelines that were not included as part of the shoreline polygon(s). These included the boundaries of ephemeral pools, inland ponds, and the interior edges of marsh channels. The determination of landscape type was based on visual inspection of the orthoimage. Process_Date: 2018 Process_Step: Process_Description: Assa14_Cost.tif This spatial coverage was created to establish boundaries to the movements of piping plover chicks (which are unable to fly pre-fledging). Development, moderate to dense vegetation, and persistent water are considered barriers to movement of plover chicks. We assumed that adults and chicks might be able to walk across temporarily exposed portions of the beach at low tide. Full methods and additional figures are provided in the associated Open-File Report (Zeigler and others, 2019). Input classification layers (Assa14_GeoSet.tif, Assa14_SubType.tif, Assa14_VegType.tif, and Assa14_VegDen.tif) are published in the larger work. All processing was performed in ArcGIS version 10.4.1. We used the ‘Combine’ tool in ArcToolbox to merge the input categorical landcover layers—geomorphic setting, substrate type, vegetation type, and vegetation density—into a single raster with a values attribute table. We added an additional column ‘Cost’ to the attribute table of this combined layer. We manually assigned a cost value of 10 to every row that contained: - ‘Development’ (substrate type, vegetation type, and vegetation density); - ‘Moderate’, ‘Dense’, or ‘Moderate or Dense’ (vegetation density); or - ‘Water’ (for substrate type; unless geomorphic setting was also 'Beach'). All remaining combinations in the attribute table were assigned a cost value of 0, indicating that there is no cost or resistance to movement through these raster cells. The cost value of 10 indicates a high cost of—or resistance to—movement. The values of 10 and 0 are arbitrary and do not impact data quality. In cases where the substrate type, vegetation type, or vegetation density were unknown (and the remaining known habitat variables did not contain a movement barrier), we allowed for movement so as not to preclude what could be a movement corridor. We converted the Cost column into a new raster layer using the ‘Lookup’ tool in ArcToolbox. In the resulting layer, cell values were equivalent to those in the ‘Cost’ column in the attribute table of the combined raster layer. We reclassified this layer such that every cell with a value of 10 was assigned NoData (-9999) and every cell with a value of 0 was assigned 1 (Reclassify tool). The output extent of the reclassification was set to that of the study area in geoprocessing settings. Thus the final Movement Cost layer indicates barriers to movement with a NoData value (-9999) and possibility of movement with value of 1. Process_Date: 2018 Process_Step: Process_Description: Assa14_DisMOSH.tif We calculated the least-cost path distance from the center of every 5x5 m raster cell to the nearest low-energy foraging area with moist substrates using the ‘Path Distance’ tool in ArcGIS (version 10.4.1). The foraging shoreline vector layer (Assa14_MOSH_Shoreline.shp) was considered the ‘Source data’ and the movement cost layer (Assa14_Cost.tif) was considered the ‘Input cost layer’. This tool calculates the least accumulative cost distance for each cell to the nearest source (foraging shoreline) while accounting for surface distance and horizontal cost factors (movement cost). The output extent was set to a custom boundary that spans the entire coverage of the Assawoman Island site relevant to the broader research program (see Zeigler and others, 2019 for more details). The extent of this custom boundary does not affect the data quality of the distance to foraging layer. We then reclassified this path distance layer using 'Reclassify'. Cells previously coded as NoData within the study area boundaries were converted to a fill value of 99,999, which denoted ‘No Access’ while cells outside the study area retained the NoData designation (-9999). We assumed that cells marked as movement barriers in the movement cost layer had no access to foraging areas. Those cells received a fill value. Please review the individual attribute descriptions as well as Zeigler and others (2019) for detailed information and example figures.
