Intersection points used to calculate rate of shoreline change statistics for New York State coastal wetlands

Metadata Updated: July 6, 2024

This data set contains intersection points used to compute rate of change statistics for New York State coastal wetlands. Analysis was performed in ArcMap 10.5.1 using historical vector shoreline data from the National Oceanic and Atmospheric Administration (NOAA). Rate of change statistics were calculated using the Digital Shoreline Analysis System (DSAS), created by U.S. Geological Survey, version 5.0. End-point rates, calculated by dividing the distance of shoreline movement by the time elapsed between the oldest and the most recent shoreline, were generated for wetlands where fewer than three historic shorelines were available. Linear regression rates, determined by fitting a least-squares regression line to all shoreline points for a particular transect, were used in areas where three or more shorelines were present. A reference baseline was used as the originating point for the orthogonal transects cast by the DSAS software. The transects intersect each shoreline establishing the intersection measurement points presented here, which were then used to calculate the rates.
