OCEANIDS Decision Support Platform: End-to-End Workflows for Maritime Spatial Planning

Copernicus Marine provides systematic reference information on the physical and biogeochemical ocean state through near-real-time monitoring, forecasts, and multi-decadal records. We present OCEANIDS, a platform and decision-support system (DSS) for climate-informed maritime spatial planning and integrated seascape management, designed to operationalise ocean and coastal data into stakeholder-oriented decision products for ports and coastal authorities.

OCEANIDS is developing an end-to-end digital workflow composed of (i) an EO & Spatial Data Platform that supports data ingestion, cataloguing, visualisation, and APIs, and (ii) the OCEANIDS Decision Support Platform (O-DSP), which exposes decision-support functionality through software services and web interfaces. Within this architecture, OCEANIDS integrates coastal, port, hazard, exposure, and risk layers and makes them available for interactive exploration and downstream processing (e.g., indicator calculation and map-based queries) through platform services.

A central objective is to connect the DSS with the Copernicus ecosystem. OCEANIDS has initiated technical exchanges with Mercator Ocean International (Copernicus Marine Service) and the Copernicus Coastal Hub to integrate relevant services and datasets into the platform while identifying gaps and emerging user needs, ensuring complementarity with existing offerings.

We will present the DSS technical architecture, integration patterns for Copernicus-derived ocean information and DTO-oriented services, and example workflows illustrating how the platform supports reproducible, on-demand decision products at regional-to-coastal scales.
