2011 profile-derived mean high water shorelines of the Outer Cape of MA used in shoreline change analysis

Metadata Updated: November 12, 2020

The Massachusetts Office of Coastal Zone Management launched the Shoreline Change Project in 1989 to identify erosion-prone areas of the coast. The shoreline position and change rate are used to inform management decisions regarding the erosion of coastal resources. In 2001, a 1994 shoreline was added to calculate both long- and short-term shoreline change rates at 40-meter intervals along ocean-facing sections of the Massachusetts coast. In 2013 two oceanfront shorelines for Massachusetts were added using 2008-2009 color aerial orthoimagery and topographic LIDAR datasets (2007) obtained from NOAA's Ocean Service, Coastal Services Center. This 2018 update includes two new mean high water (MHW) shoreline positions for the Massachusetts coast extracted from lidar data collected between 2010-2014. Shorelines were extracted using a few different methods to establish the MHW shoreline position. The 2010 shorelines along the North Shore and South Coast are from lidar data collected by the U.S. Army Corps of Engineers (USACE) Joint Airborne Lidar Bathymetry Technical Center of Expertise (JALBTCX). The 2011 shorelines along the South Shore and Outer Cape are from lidar collected by the U.S. Geological Survey's (USGS) National Geospatial Program Office. The 2012 shorelines along Nantucket and Martha’s Vineyard are from a U.S. Army Corps of Engineers Post Sandy Topographic lidar survey. The 2013-2014 shorelines along the North Shore, Boston, South Shore, Cape Cod Bay, Outer Cape, South Cape, Nantucket, Martha’s Vineyard, and South Coast west of Buzzards Bay are from lidar collected by the U.S. Geological Survey's (USGS) Coastal and Marine Geology Program.
