Summary

This dataset includes New York State historical shoreline positions represented as digital vector polylines from 1880 to 2015. Shorelines were compiled from topographic survey sheets from the National Oceanic and Atmospheric Administration (NOAA). Historical shoreline positions can be used to assess the movement of shorelines through time. Rates of shoreline change were calculated in ArcMap 10.5.1 using the Digital Shoreline Analysis System (DSAS) version 5.0. DSAS uses a measurement baseline method to calculate rate of change statistics. Transects are cast from the reference baseline to intersect each shoreline, establishing measurement points used to calculate shoreline change rates. For wetland shorelines these rates can be interpreted [...]

Purpose

This data set is part of a cooperative agreement between USGS and New York State Department of Environmental Conservation to assess coastal wetland vulnerability within the state. Monitoring shoreline change enables quantification of land loss or gain over time, determined by the balance between erosion and accretion along coasts. Metrics such as this are valuable to management decision makers in evaluating long-term wetland viability. For coastal wetlands, erosion along the water boundary causes a loss of ecosystem services, such as habitat provision, carbon storage, and wave attenuation.
