Description:
Abstract:
Understanding how sea-level rise will affect coastal landforms and the species and habitats they support is critical for crafting approaches that balance the needs of humans and native species. 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 shoreline polygons (fiis10_shoreline.shp) are a generalized delineation of the mean high water (MHW) position on the seaward face of the island and mean tidal level (MTL, average of MHW and mean low water) position on the inland face. They delineate the shoreline for the purposes of this study. These polygons were used to convert the transects to 5-m points and to measure island width, distance to inlet from each transect, and position of the shoreline (see larger work). In addition, the inlet delineation polylines (fiis10_inletLines.shp) use single straight line segments to roughly locate each side of tidal inlets for the barrier island study area. These lines were used (1) to designate the transition between ocean-facing and land-facing sides of the barrier island and (2) to measure the distance to tidal inlet in the 5-m points dataset (see larger work). They were created manually to cross the MHW contour line on each side of a tidal inlet within the study area.

Data_Quality_Information:
Logical_Consistency_Report:
The shoreline shapefile (fiis10_shoreline.shp) consists of polygon data produced from elevation data and tidal datum values through an automated process described below. It was not checked for topological consistency. The inlet delineation shapefile (fiis10_inletLines.shp) consists of manually created line data. No checks for topological consistency were performed on these data.
Completeness_Report:
fiis10_shoreline.shp: The polygons represent a generalized outline of the land above water. Polygons within 30 m of each other were aggregated and land masses and polygon holes less than 300 m2 were eliminated (Aggregate Polygons tool in Cartography toolbox, ArcGIS 10.5). Polygon outlines were compared to ancillary datasets, such as elevation and orthoimagery. The delineation is generalized and should not be used for any purpose that requires precision or accuracy, such as navigation or engineering.
fiis10_inletLines.shp: All points where the barrier island alongshore shoreline is broken are located in these data. If one side of a delineated inlet was not within the study area, that side was not delineated.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
fiis10_shoreline.shp: Positional accuracy is dependent on the accuracy of the input datasets (DEM and shoreline points) and on the generalization routines used to create these polygons. For any given section, these outlines are assumed to be accurate within 25 m. However, the assumed accuracy along the seaward edge of the shoreline is much greater. For the greatest shoreline accuracy, refer to the shoreline points (fiis10_SLpts.shp in larger work) that were used to derive the seaward side of the shoreline.
fiis10_inletLines.shp: These data are an approximation. Their assumed positional accuracy is 5 m.

Process_Description:
Full methods are provided in the associated Methods OFR (Zeigler and others 2019).
fiis10_shoreline.shp:
A polygon outlining the shoreline of the island was created for the study area. On the ocean-facing side of the island, this was considered the MHW contour (Weber and others 2005, Zeigler and others 2019). To include partially submerged wetland on the estuarine-side, the land-facing shoreline was delineated at mean tidal level (MTL), which was calculated from the local MHW and mean low water (MLW) levels at the given study area.
The local MLW elevation was estimated from NOAA’s VDatum (2014 release) as the average MLW elevation at a sample of nearshore points in the study area. Experimentation conducted as part of this study found that the MTL delineation more consistently identified the boundary between marsh (intertidal vegetation) and submerged areas than either MHW or MLW. For consistency with the MHW offset applied throughout the project, MHW was used as part of the calculation of MTL.
To create this shoreline, we performed the following steps. Most of the steps were performed programmatically using the function functions_warcpy.DEMtoFullShorelinePoly in bi-transect-extractor (Sturdivant, 2019):
1. Convert the shoreline points CSV to a multipoint feature class in reference system NAD_1983_UTM_Zone_18N. This was performed in ArcGIS 10.5 using the tools Make XY Event Layer and Project. The datum transformation used was WGS_1984_(ITRF00)_To_NAD_1983 (WKID: 108190, accuracy: 0.1 m).
2. Manually digitize lines from the DEM that indicate where land meets a tidal inlet, which is considered the division point between the oceanside and the bayside or estuarine side of the island. This line was visually approximated.
3. Create a generalized polygon from the DEM in which every cell within the polygon is above MHW (MHW polygon). This was performed programmatically using the function functions_warcpy.RasterToLandPerimeter in bi-transect-extractor v1.0 (Sturdivant, 2019) with a MHW elevation of 0.46 m NAVD88, calculated for the area by Weber and others (2005). The process includes generalizing the polygons (Aggregate Polygons tool in the Cartography toolbox) using an aggregation distance of 10 m, a minimum area of 300 m, and a minimum hole size of 300 m.
4. Repeat Step 3 for MTL, using an MTL elevation of -0.275 m NAVD88.
5. Merge the polygons so that the MHW contour outlines the island on the oceanside and the MTL contour outlines the island on the bayside, divided at the delineated tidal inlets. To do so, create a symmetrical difference polygon between MHW and MTL polygons (SymDiff) and split the resulting polygon at the inlet lines (Feature to Polygon). Create a polygon that outlines only the bayside area that is above MTL and below MHW (MTL-only polygon) by deleting the segments of the symmetrical difference polygon that overlap shoreline points (Spatial Join, Erase). Merge the MTL-only polygon with the MHW polygon (Union, Dissolve). This was performed using the function functions_warcpy.CombineShorelinePolygons in bi-transect-extractor (Sturdivant, 2019).
6. Adjust the vertices of the polygons to precisely match the MHW shoreline positions wherever they are within 25 m of each other (Doran and others, 2017). This was performed using the function functions_warcpy.NewBNDpoly in bi-transect-extractor (Sturdivant, 2019). That snaps the polygon to the shoreline points where it is within 25 m of a point (Snap tool in the Edit toolbox, ArcGIS 10.5).
7. QA/QC the output and manually revise any sections where the point snapping created clearly incorrect artifacts.
The dataset contains 152 polygons.

Display the DEM with a color break at mean high water (MHW) elevation. Manually digitize a straight line that bisects MHW where the seaward shoreline land meets a tidal inlet, which is also considered the division point between the ocean-side and bay- or estuarine-side of the island. This line was visually approximated. The dataset contains 3 polylines.
