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 dataset described here identifies the Euclidean distance from the center of each 5x5 m GeoTiff cell within the boundaries of the Myrtle Island, Virginia study area to the ocean, with the ocean boundary being the mean high water (MHW) ocean shoreline, according to lidar captured in 2014. See Zeigler and others (2019) for additional details. This dataset is part of a series of spatial datasets used to describe characteristics of barrier islands found along the North American Atlantic coast in order to identify habitat for the federally protected piping plover (Charadrius melodus). 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.

The portion of this shoreline adjacent to the open ocean, which is the only component of the shoreline relevant to the present dataset, was originally derived from mean high water (MHW) shoreline points (myr14_SLpts.shp in larger work; 14CNT01_morphology.csv in Doran and others, 2017). These shoreline points were QA/QC'd in ArcMap and edited in MATLAB. The shoreline was not further checked for topological consistency. No further logical accuracy tests were conducted on the present dataset. Completeness_Report: This dataset is clipped to a custom boundary and may not include the entire spatial extent of source datasets as they are published in original form. However, the custom boundary spans the entire coverage of Myrtle Island relevant to the broader research program (see Zeigler and others, 2019 for more details). This dataset is therefore 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: We assume an accuracy within 5 m horizontally. No formal accuracy assessments of the horizontal positional information in the dataset have been conducted. However, the accuracy is dependent on that of the source data. Horizontal accuracy is inherited from the edges of the shoreline polygons (myr14_shoreline.shp in the larger work) adjacent to the open ocean, which were derived from the shoreline points (myr14_SLpts.shp in larger work). Ocean-facing segments of the shoreline polygons are accurate to about 5 m. Shoreline point coordinates were transformed with the datum transformation WGS_1984_(ITRF00)_To_NAD_1983 (WKID: 108190, accuracy: 0.1 m) using the 'Project' tool in ArcGIS. This raster file was created in reference system North American Datum (NAD) 1983 Universal Transverse Mercator (UTM) zone 18N at a resolution of 5 m. Lineage: Process_Step: Process_Description: Full methods are provided in the associated USGS Open-File Report (Zeigler and others, 2019). The following steps were all performed in ArcGIS 10.4.1. Using ArcGIS, we started by locating the ‘ocean’ boundary in the study area. Using the geomorphic settings GeoTIFF (Myr14_GeoSet.tif in larger work), we selected all raster cells defined as ‘beach’ and exported the selected features as a polygon using the ‘Raster to Polygon’ conversion tool. Here, ‘beach’ is defined as the area between the shoreline (myr14_shoreline.shp contained in the larger work) and the study area boundary. The custom study area boundary spans the entire coverage of Myrtle Island relevant to the broader research program (see Zeigler and others, 2019 for more details). Its extent beyond the Myrtle Island site is otherwise irrelevant and does not affect data quality or completeness. In an Edit session in ArcGIS, we used the ‘Cut Polygons’ tool to manually clip the beach polygon so that only the portion of the polygon on the ocean-facing side of the barrier remained. The mean high water (MHW) shoreline points (myr14_SLpts.shp in larger work) were referenced to identify the extent of the ocean-facing portion of the beach. For these purposes, this clipped beach area from the MHW shoreline seaward to the edge of the study area was considered the ocean boundary. Using the ‘Euclidean Distance’ tool, we created a raster layer with a 5x5 m cell size that measured the straight-line distance from each cell within the study area to the closest cell in the clipped beach polygon (considered the ocean boundary). Cells landward of the MHW shoreline received a positive distance to ocean value and those seaward of the MHW shoreline received a value of 0 m. See Zeigler and others (2019) for example figures. No transformations were performed because shoreline polygons and geomorphic setting rasters were acquired in the NAD83 UTM projection.
