This map consists of long-term (100+ years) shoreline change rates for the lower 48 states of the United States and Hawaii. Rate calculations were computed within a GIS using the Digital Shoreline Analysis System (DSAS) version 4.1, an ArcGIS extension developed by the U.S. Geological Survey. Long-term rates of shoreline change for the lower 48 states were calculated using a linear regression rate based on all available shoreline data. Long-term rates of shoreline change for Hawaii were calculated using a weighted 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.
