This dataset consists of transects intersect points used by the Digital Shoreline Analysis System (DSAS) to calculate rate-of-change statistics. Rate calculations were computed within a GIS using the DSAS, an ArcGIS extension developed by the U.S. Geological Survey. Long-term rates of shoreline change were calculated using a linear regression rate based on all available shoreline data. A reference baseline was used as the originating point for the orthogonal transects cast by the DSAS software. The transects intersect each shoreline establishing measurement points, which are then used to calculate long-term rates.
