U.S. Geological Survey


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 Desktop 10.x and MATLAB component runtime library utility (free download)

Previous Versions: DSAS for ArcGIS 9.x
