EGDI Multifunctional 2D/3D Decision-Support Module

The EGDI Multifunctional 2D/3D Decision Support Module plays a crucial role in improving decision-making for both coastal vulnerability assessment and offshore windfarm siting. This document provides an in-depth inventory of existing Decision Support Systems (DSSs), Decision Support Tools (DSTs), and Decision Support Indices (DSIs) used by Geological Survey Organisations (GSOs) across Europe. The study is based on a structured questionnaire circulated among GSOs to gather insights into their methodologies, tools, and outputs. By evaluating current practices and identifying gaps, this report lays the foundation for future improvements in decision-support frameworks.
