The shoreline polygons (cei12_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 (cei12_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.
