Rates returned as feature class: rate information is automatically spatially joined to DSAS transects for faster visualization.ĭata visualization: rates of change are added to the map view with pre-set color ramps for rapid display and interpretation of results.īeta shoreline forecasting: future shoreline horizons calculated with uncertainty bands for advanced interpretation of forecasted changes. Updates from the original in version 5.1 include the following:Īdvanced baseline placement options: Baselines located onshore, offshore, midshore (new!) or any combination of baseline orientations are now accepted.Īttribute Automator: a tool for easily adding required and optional attribute fields to shoreline and baseline data.
#ARCGIS 10.3 RELEASE UPDATE#
This update builds on the capabilities of the previous version-DSAS v5.0 (Himmelstoss and others, 2018).
#ARCGIS 10.3 RELEASE HOW TO#
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 informatioĭSAS version compatibility with ArcGIS and Windows DSAS version 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 the robustness of the rates, 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.
