Geometry Type: esriGeometryPolyline

Description: The United States Geological Survey's (USGS) Digital Shoreline Analysis System (DSAS) was used to calculate shoreline change rates for 67 islands . All islands examined were within Forsythe Wildlife National Refuge or proximal to Long Beach Island. Shoreline statistics were computed every ≈ 20 meters using the 1977 NJ Tidelands Claim line and the 2015 NJ Land Use/Land Cover. The results of this analysis include Net Shoreline Movement, Shoreline Change Envelope, and End Point Rate. In addition, for each island the average rates were calculated to make interisland comparison easier. NOTE: A Value of -9999 indicates that DSAS was not run on the selected island.
