This software computes the rate of shoreline change using historical shoreline positions represented in a GIS. The software can also be used to compute rates of change for other boundary change issues that incorporate a clearly identified feature position at discrete times.

Requires ArcGIS 10.4–10.7


  • Analyze shoreline change using a GIS
  • Calculate rate-of-change statistics from multiple shoreline positions
  • Produce FGDC-compliant metadata
