This update builds on the capabilities of the previous version-DSAS v5.0 (Himmelstoss and others, 2018). Update to location of land relative to baseline data: In the Default Parameters window, Baseline Settings tab, there is a new visualization symbol to assist users in identifying the orientation of land relative to baseline data, left (L) or right (R). We are currently considering multiple options for future development of DSAS.īias Feature: The optional proxy-datum bias information will no longer be stored as a table: it is now stored and accessed by DSAS through a polyline feature class.
* The USGS DSAS development team is aware that ArcMap Desktop is nearing the end of its supported life. An in-depth user guide and video tutorials are available that provide detailed instruction on the DSAS workflow including: how to define a reference baseline for measurements, the steps needed to generate automated measurement transects and metadata based on user-specified parameters, guidelines on how to manually add or edit existing transects, and an explanation of the visualization options to display calculated rates of shoreline change and other statistical information.ĭSAS version compatibility with ArcGIS and Windows DSAS versionĪt this time, DSAS is not compatible with ArcPro. However, ArcMap Desktop and ArcPro can be installed and run at the same time allowing DSAS to function. A user-friendly interface guides the user through the major steps of shoreline change analysis. It provides an automated method for establishing measurement locations, performs rate calculations, provides the statistical data necessary to assess rate robustness, and includes a beta model of shoreline forecasting with the option to generate 10 and/or 20-year shoreline horizons and uncertainty bands.
The Digital Shoreline Analysis System (DSAS) v5 software is an add-in to Esri ArcGIS desktop (10.4-10.7+) that enables a user to calculate rate-of-change statistics from multiple historical shoreline positions.
