The EO4EU project is committed to fostering transparency, collaboration, and innovation in Earth Observation (EO) data processing. As part of this effort, we have open-sourced the EO4EU platform components developed during the project to make them accessible to all stakeholders. The EO4EU platform enables users to retrieve and process data from heterogeneous data sources, supporting advanced workflows for EO data exploitation. These components include: • Knowledge Graph – to search and link EO data from heterogeneous data sources. • Machine Learning Processing Components – enabling automated analysis and predictive modelling, based on EO4EU use cases. • Orchestration Components – managing workflows and resource allocation across the platform. • User Interfaces – providing different means to access the EO data and services provided by the EO4EU platform.
