Update 2.0 to Coastal dynamics analyzer (CDA): A QGIS plugin for transect and area based analysis of coastal erosion

Abstract

The Coastal Dynamics Analyzer (CDA) v.2.0 is an enhanced version of the existing QGIS plugin, CDA v.1.0, which was originally developed for transect-based analysis (TBA) in coastal erosion assessment. This new release introduces the Area-Based Analysis (ABA), a new methodology useful for analyzing irregular or dynamic shorelines. By integrating ABA, CDA v.2.0 enables users to evaluate broader coastal dynamics and changes, providing a more comprehensive toolkit for researchers and professionals engaged in coastal monitoring and management. The plugin maintains its user-friendly interface and compatibility with QGIS, ensuring seamless integration into existing workflows.
