GIS-based DSS for optimal placement for oceanic power generation: OCEANLIDER project, Spanish coastline study

A GIS-based Decision Support System has been developed within the OCEANLIDER project to find optimal placement for green energy generation from oceanic energy. The DSS performs Multi-Criteria Evaluation, MCE, to help in the decision making. The scenario is defined as a combination of the device (power generation from wave or sea current energy) and its geographical location. The criteria used in the decision are physical constraints, together with operational, resource-related, and environmental constraints. Each criterion is computed using both Boolean and fuzzy values, and they can be combined in multiple ways (fuzzy-and, fuzzy-or, weighted linear combination). Finally, the MCE is done using Ordered Weighted Average to allow for multiple actors, multiple risk policies.
