SAGE partner CREAFhosts an open codesprint focused on integrating all types of data into the GDDS, together with OEMC, CitiObsand more4natureprojects.
When: 5 – 6 October 2026
Where: Casa Convalescència, Barcelona (Spain)
Registration: Follow this link
A hands-on hackathon where researchers, developers, and environmental data professionals will work together to integrate citizen science and remote sensing data into the Green Deal Data Space (GDDS). It is a unique opportunity to work with real datasets, test a live Proof of Concept data space, and contribute to an official OGC Engineering Report. No prior experience with the GDDS is required.
European Data Spaces are designed to enable secure and sovereign data exchange, ensuring that participants retain full control over their data. Among the several data spaces currently under development across the EU, the Green Deal Data Space (GDDS) stands out for its broad scope, which directly intersects with a wide range of environmental data, including remote sensing products and citizen-generated observations.
This codesprint presents a unique hands-on opportunity to test the Proof of Concept of the GDDS recently deployed by SAGE. The practical work will be organized in threads. One thread aims to demonstrate how the remote sensing data, as those created by the OEMC project in the last 3 years, can be exposed in the GDDS. In a second thread, the codesprint will explore how to include citizen science data in the GDDS. A third thread will explore how to make the GDDS more useful in combination with other data spaces. The results of this codesprint will be compiled into an Engineering Report that will be presented to the OGC for its approval for publication. This event is organized by CREAF in collaboration with the OEMC, SAGE, CitiObs, more4nature projects, funded by the European Union, and the EuroGEO GDDS Action Group.
What will you do?
- Test and explore the GDDS recently deployed by SAGE as a Proof of Concept.
- Integrate remote sensing datasets from the OEMC project and beyond into the GDDS.
- Explore how citizen-generated data, including wearable sensors and community observations, can be made accessible through open, interoperable standards.
- Contribute to shaping how Europe manages and shares its environmental data.
Who Should Attend?
This codesprint is designed for participants with a technical oriented background, some level of development and an interest in data spaces, environmental monitoring, remote sensing, and/or citizen science. We welcome people from a wide range of profiles, including:
- Researchers and scientists working with remote sensing, Earth Observation, or citizen-generated environmental data who want to explore how their datasets can be integrated into the GDDS.
- Data engineers and developers capable of developing software around data spaces, APIs, OGC standards, DGGS, or SensorThings API (STAplus) who want to contribute to real-world technical challenges.
- Representatives from EU-funded projectsconnected to or beyond supporting projects.
- OGC community members and open data & FAIR data advocates interested in testing interoperable, federated data infrastructures.
Why attend?
- Collaborate directly with the teams building the future of European data spaces.
- Warm up for the OEMC Global Workshop with practical work based on the OEMC results.
- Work with actual datasets from 5 major EU-funded projects and initiatives
- Learn how to apply OGC standards for data sharing and making data FAIR
- Contribute to an official OGC Engineering Report, a recognised output in the international geospatial community.
- Connect with researchers, engineers, and policymakers working at the forefront of open environmental data in Europe.
- No prior experience with the GDDS is required, just bring your expertise in geospatial data, APIs, or environmental datasets.
About the contributing projects
SAGE is a Digital Europe co-funded project that is developing a federated, secure and interoperable data space to support key pillars of the European Grean Deal. At this Codesprint SAGE contributes to the testing of the GDDS recently deployed as a Proof of Concept.
OEMC is an EU-funded project accelerating Europe’s capability to process high-quality, user-friendly, environmental observation based on Earth Observation data and the FAIR principles. At this Codesprint participants will explore how to give access to project results in the GDDS.
CitiObs is an EU co-funded project enhancing citizen observatories for healthy, sustainable, resilient and inclusive cities. At this Codesprint participants will explore how to give access to wearable sensors using DGGS and STAplus in the GDDS.
more4nature is an EU co-funded project that aims to bring about transformative change in environmental protecting by including citizens and communities as key actors in collaborative environmental compliance assurance. At this Codesprint participants will explore how to give access to some of the citizen-generated data from the 40 project cases in the GDDS.
EuroGEO GDDS Action Group focuses on defining how the GDDS could contribute to the Group on Earth Observations (GEO). The group’s agenda includes understanding GDDS through existing use cases, consolidating diverse perspectives, discussing governance, and outlining future plans.
