USGS Digital Shoreline Analysis System (DSAS)
Entry ID: USGS_DSAS


Summary
Abstract: The Digital Shoreline Analysis System (DSAS) version 2.2.1 extends the normal functionality of the ArcView© version 3.2 (and later) geographic information system to include historic shoreline change analysis. The DSAS 2.2.1 was developed by the USGS in cooperation with TPMC. The application extension is designed to efficiently lead a user through the major steps of shoreline change analysis in a clearly organized and attractive user interface. This extension to ArcView contains three main components to assist a user to define a baseline, generate orthogonal transects at a user defined separation along the coast and to calculate rates of change (linear regression, endpoint rate, average of rates, average of endpoints, jackknife). The extension utilizes Avenue code to develop transects and rates and uses the Avenue programming environment to automate and customize the user interface.
