<abstract>Understanding the potential effects of sea level rise (SLR) on coastal landforms and the species and habitats they support will be critical for crafting approaches that balance the needs of both humans and native species. Given this increasing need to develop the capability to forecast sea-level rise impacts on barrier islands in the near- and long-term, 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, i.e. lidar, orthophotography, and geomorphic feature sets derived from those, to extract metrics of barrier island characteristics at consistent sampling distances for incorporation into these models and into the training data used to parameterize these models. This data release contains the resulting 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 at a range of coastal 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 ecological value, ecosystem services, and habitat suitability of beaches in the face of storm impacts, climate change, and sea-level rise. These data were produced for the barrier islands corresponding to the Fire Island National Seashore, NY.
</abstract>
<purpose>The upper beach width was calculated for each transect (see larger work) for use in geomorphology modeling. It was converted from vector to raster format for use in modeling shorebird habitat suitability.</purpose>

Accuracy of the beach width value is dependent on the accuracy of the lineage data, which can be viewed in the dataset containing transect-averaged values in the larger work. To ensure direct agreement between the transects and this raster version, the transects colored by beach width were overlaid on the raster surface colored by beach width. The beach width values were spotted checked while verifying the reliability of the transect values. Spot checks were performed by plotting the beach width on a cross-shore elevation profile with the available dune positions positioned on the plot as well. These values were always found to be in agreement unless reported elsewhere. More detail is provided in the associated Open-File Report (Zeigler and others, 2018), in the source code (https://code.usgs.gov) and in the Entity and Attribute Information.

<logic>With increasing distance of a cell from the seaward face of the island, there is less likely to be a direct orthogonal relationship between the cell value and the beach because transects were shortened to eliminate overlap prior to assigning the line values to the raster grid. Cells may not have the same value as neighboring cells directly seaward because of the same overlap-elimination process applied to the transects.</logic>

Full methods are provided in the associated Methods OFR (Zeigler and others 2018). For the detailed documentation of the processing, see the source code (https://code.usgs.gov).
The width of the upper beach (from mean high water (MHW) shoreline to either dune crest, dune toe, or coastal armoring/development) is calculated along shore-normal transects. These transects populated with all relevant calculations are included in the larger work.
Calculate beach width along transect
To calculate the beach width for the transects, upper beach width (uBW) is calculated based on the difference in position between two points: the position of MHW along the transect (SL_x, SL_y) and the dune toe position or equivalent (usually DL_x, DL_y). It is calculated as follows, relying primarily on numpy and the snapToLine geometry method in ArcPy, and using pandas for data storage/organization: (1) find the position along the transect of an orthogonal line drawn to the dune point (DL_x, DL_y and DH_x, DH_y); (2) calculate distances from MHW to the position along the transect of the dune toe (DistDL), dune crest (DistDH), and armoring (DistArm); (3) conditionally select the appropriate feature to represent "top of beach." Dune toe is prioritized. If it is not available and DH_zMHW is less than or equal to maxDH, use dune crest. If neither of the dune positions satisfy the conditions and an armoring feature intersects with the transect, use the armoring position. If none of the three are possible, uBW will have a fill value (-99999); (4) copy the selected distance to shoreline (Dist--) to uBW.
Assign values to raster
A transect ID raster was created from the same transect file used to produce the 5-m points (see larger work). Those transects were modified from the supplemented NASC transects by manually shortening overlapping transects to the first point of intersection. When a transect overlapped with a supplementary transect, the supplementary transect was shortened to the intersection point. The beach width values from each transect are assigned to the cells that represent that transect using the JoinField tool in the data management toolbox.

<overview>
<eaover>The upper beach width is the distance along a shore-normal transect between the mean high water (MHW) shoreline and either dune crest, dune toe, or coastal armoring/development. The fill value is -99999 and indicates that the beach width is unknown.</eaover>
