Online_Linkage: https://doi.org/10.5066/P970QVB1 Online_Linkage: https://www.sciencebase.gov/catalog/item/5bc4e911e4b0fc368eba1b2d Description: Abstract: This data release of dune metrics for the Massachusetts coast is part of a 2018 update to the Massachusetts Shoreline Change Project. Because of continued coastal population growth and the increased threat of coastal erosion, the Massachusetts Office of Coastal Zone Management (CZM) launched the Shoreline Change Project in 1989 to identify erosion-prone areas of the coast. Maps of historic shoreline locations from the mid-1800s to 1978 were produced from multiple data sources, and in 2001, a 1994 shoreline was added to enable the calculation of long- and short-term shoreline change rates. In 2013, the U.S. Geological Survey (USGS), in cooperation with CZM, delineated an additional oceanfront shoreline using 2007 topographic lidar data and 2008–9 color aerial orthoimagery. Further cooperation between CZM and the USGS resulted in this 2018 update, intended to increase the understanding of coastal erosion and to support coastal management decision making. This update includes beach shorelines, marsh shorelines, and dune metrics, all of which were derived from topographic lidar data. This data release, which is part of the 2018 update, defines the position and elevation of the most seaward dune crest and toe along the Massachusetts coast as derived from 2013–14 lidar data. In the absence of a dune, the peak of the berm or the seaward edge of a bluff, headland, or hard structure (for example, a seawall, road, or parking lot) was chosen as a proxy for the dune crest. Where possible, the dune toe was placed at the base of the proxy feature. Purpose: This dataset provides the elevation and position of the crest of the most seaward dune along the Massachusetts coast. Dune crest and toe elevation data are essential parameters for determining the vulnerability of coastal areas from storms. Dune crest elevation is used as a threshold for determining the probability of overwash and inundation due to waves and storm surge. Dune toe elevation is used to determine the probability of collision (erosion of the base of the dune), and dune toe location allows for the calculation of both beach width and beach slope. Supplemental_Information: The crest of the most seaward sand dune is often the first line of defense for coastal areas during storms. Determining the probability of collision, overwash, or inundation during a storm is just as vital in regions where no dunes are present. Therefore, in the absence of a dune, the peak of the feature that would serve as the first line of defense was chosen as a proxy for the dune crest. This includes the seaward-most edge of a headland, bluff or other hard structure (e.g., seawall, road, parking lot), or the peak of the berm. Where possible, the dune toe was placed at the base of these proxy features. Accompanying dune toe position and elevation data are available from the larger work citation.

Online_Linkage: https://pubs.usgs.gov/of/2012/1084/ Data_Quality_Information: Logical_Consistency_Report: The dune features were QA/QC’d on aerial imagery in both ArcMap and Google Earth, on the gridded elevation surfaces in ArcMap, and on the grid profiles in MATLAB to ensure that appropriate features were chosen. Points were adjusted or deleted as necessary. In the absence of a dune, the seaward edge of the headland, bluff or hard structure (e.g., seawall, road, parking lot), or the peak of the berm was chosen as the dune crest. Each dune crest point was assigned a “Class” value so that actual dunes could be distinguished from other features (See Process Step 2 for details on the classification system). If the dune crest was located at the edge of a hard structure or bluff, the dune toe was placed at the base of that feature. It is possible to have a dune crest but no corresponding dune toe for any profile if the dune toe was not discernable by the automatic algorithm or if it did not meet quality assurance standards. Completeness_Report: This dune crest data set is complete for all regions in Massachusetts where this method could be used (i.e., regions where a shore-parallel reference line was available). These data adequately represent the dune crest at the time of the survey. Remaining gaps in the dune data are a consequence of gaps in the lidar data, an unresolvable dune feature due to vegetation or structures that resulted in too much noise, features with indistinct edges (e.g., headlands or bluffs), or points that did not meet quality assurance standards. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Horizontal accuracy of the dune crest and dune toe positions is estimated to be 0.42 m which is the horizontal accuracy of the lidar data at the 95 percent confidence level. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: The calculated vertical error for each dune crest and toe point was based solely on the scatter of the lidar data in the grid cells. However, vertical accuracy is also partially dependent on the positional accuracy of the lidar data itself which is 0.189 m at the 95th percentile level for this data set.

Process_Step: Process_Description: 2013–14 lidar elevation data were downloaded from NOAA’s online data access viewer (https://coast.noaa.gov/dataviewer/#/) in LAS format (NAD83 2011, UTM Zone 19N (meters) and NAVD88 (meters)) for ten regions along the Massachusetts coast. These regions include: the North Shore, South Shore, Cape Cod Bay, Outer Cape, South Cape, part of the South Coast along Buzzard’s Bay, the southwestern, southern, and eastern coastlines of Martha’s Vineyard, the Vineyard Sound-facing coastline of Martha’s Vineyard, the Atlantic Ocean-facing coastlines of Muskeget, Tuckernuck, and Nantucket Islands, and the Nantucket Sound-facing coastlines of Muskeget, Tuckernuck, and Nantucket Islands. Each of the ten regions has its own coast-following reference line along which the lidar data are processed, and each reference line is divided into segments. The lidar point data were processed segment by segment along each region’s reference line to extract the peak of the most seaward dune following methods developed by Stockdon and others, 2012. The elevation data for each segment were interpolated in MATLAB 2017a to create a shore-parallel grid with a resolution of 10 m in the longshore direction and 2.5 m in the cross-shore. Each 10 m wide grid row is a cross-shore profile along which dune features are extracted. Each segment grid begins at profile number one, and for each profile, the MATLAB dune crest extraction algorithm finds inflection points in the slope of the data, classifies them as peaks and troughs, and selects the highest peak as the crest of the dune. The vertical error, which is based on the scatter of the data, is also calculated for each point. See Stockdon and others, 2012 for details. The MATLAB algorithm was run for all segments in each region. Within the program, the geographic coordinates (WGS84) were calculated for each point and the automatically-extracted dune crest data, which includes dune crest elevation, error, and location in both eastings/northings and latitude/longitude, were written to ArcGIS shapefiles using MATLAB’s shapewrite.m script and Keyhole Markup Language (kml) files. The dune crest locations were manually examined to ensure that an appropriate and consistent alongshore feature was identified. This was done by simultaneously viewing the data in three ways: dune crest kml files were viewed on 2014 Google Earth imagery, the shapefiles were viewed on DigitalGlobe world imagery in ArcMap, and the dune crest and lidar data (interpolated and point data) were viewed for each grid profile in a MATLAB Graphical User Interface (GUI). The GUI allowed for the deleting or moving of dune crest points as necessary to produce a final shapefile of dune peaks for each region. In the absence of a dune, the beach berm or seaward edge of the headland, cliff, bluff or hard structure (e.g., road, parking lot, seawall) was extracted since those features would serve as the first line of defense during a storm. Much manual editing and deleting was required in developed regions as well as in regions with complex topography. The dune crest shapefiles for each of the ten regions were combined in ArcMap (ArcToolbox >> Data Management Tools >> General >> Merge) to create a final shapefile of dune crest position and elevation for the entire state.

The dune crest points were viewed over imagery (2014 Google Earth Imagery and DigitalGlobe world imagery in ArcMap), and each point was assigned one of four classes based on the material of the feature and its susceptibility to erosion: 1). The dune crest point is at the peak of a dune, the berm crest of a sandy beach, or the top seaward edge of a bluff. 1A). (1-Armored) The dune crest point is at the peak of an armored dune or the top seaward edge of an armored bluff. Armoring usually consisted of a rocky wall at the base of the feature. Note that sand fencing isn’t considered armoring so dunes with sand fencing were classified as (1), not (1A). 2). The dune crest point is at the crest of a rocky beach or at the top seaward edge of a cliff or headland. 3). The dune crest point is at the top seaward edge of a hard (non-natural) structure such as a road, parking lot, seawall, etc.). A coordinate system transformation of the dune crest data was required for the points to correspond with the beach and marsh shoreline data that are part of this update to the Shoreline Change Project. Using ArcGIS version 10.5, the dune crest shapefile was transformed from the UTM zone 19 (NAD83 2011) coordinate system to the WGS84 geographic coordinate system (ArcToolbox >> Data Management Tools >> Projections and Transformations >> Project) using the “NAD_1983_HARN_To_NAD_1983_2011 + NAD_1983_HARN_To_WGS_1984” transformation. The DBF file of the shapefile was then saved as a CSV file using Microsoft Excel (version 2016).
