The National Assessment of Shoreline Change: A GIS Compilation of Vector Shorelines and Associated Shoreline Change Data for the New England and Mid-Atlantic Coasts
This compilation of open-ocean, sandy shorelines for New England and the Mid-Atlantic is part of a series that already includes published shoreline data for the Gulf of Mexico, Southeast Atlantic, and California coasts (Morton and others, 2004; Morton and others, 2005; Hapke and others, 2006) and will eventually include reports for the Pacific Northwest, and parts of Hawaii and Alaska. The New England and Mid-Atlantic shoreline data differ from previously published U. S. Geological Survey (USGS) reports in the series in that the prior shoreline change analyses restricted data to four total shorelines representing specific time periods. The New England and Mid-Atlantic shoreline data incorporate all available shorelines that can be quality-checked. The historical shorelines cover a variety of time periods ranging from the 1800s through the 2000s, and the modern, lidar-derived shoreline was from data collected in 1997 or 2000. The New England and the Mid-Atlantic Coasts were subdivided into a total of ten analysis regions for the purposes of reporting regional trends in shoreline change rates. |
