    "descript": "This shapefile consists of Dauphin Island, AL shorelines extracted from lidar data collected from November 1998 to January 2014. This dataset contains 14 Mean High Water (MHW) shorelines separated into 37 shoreline segments alongshore Dauphin Island, AL.  The individual sections are divided according to location along the island  and shoreline type: open ocean, back-barrier, marsh shoreline.  Raw lidar point data was converted to a gridded surface, from which a contour of the operational MHW shoreline (0.24 m North American Vertical Datum of 1988 [NAVD 88]; Weber and others, 2005) was identified and extracted.  This produced a continuous MHW shoreline for each of the lidar datasets from 1998 \u2013 2014.  Shorelines for all 14 dates were compiled into a database for use with the Digital Shoreline Analysis System (DSAS; Thieler and others, 2009) to quantify rates of shoreline change over the 1998-2014 time period. The migration of shorelines through time is presented as the linear regression rate (LRR) in the associated transect files (https:\/\/coastal.er.usgs.gov\/data-release\/provisional\/ip086178\/).",
