0 likes476 views
The document discusses the challenges of integrating big data in the Global Earth Observation System of Systems (GEOSS), highlighting the importance of data sharing principles for societal benefits. It presents economic benefits from open data policies and outlines plans for future activities related to space and security, including stakeholder engagement and technical assessments. The document emphasizes the need for coordinated earth observations to inform decision-making for disaster resilience and critical infrastructure protection.

- 19. Development of capabilities and solutions to enhance: – The resilience of society against natural and human- induced disasters; – The protection of critical infrastructures; and – The efficiency in tasks related to border and maritime surveillance as well as to civil protection and humanitarian aid. GEO Space and Security Community Activity
- 20. Progress in 2016 • Announced the Space and Security Community Activity (CA): – ESA-SatCen-JRC Big Data from Space Conference; – ESA Living Planet Symposium; – ESA EO Open Science Conference; – SatCen Big Data in Secure Societies Workshop); and – A number of other events (e.g. the SatCen Expert User Forum). • Explored synergies with H2020 projects (e.g. BigDataEurope and EVER-EST) and ensured SatCen participation in the H2020 NextGEOSS project (which will start at the end of 2016).
- 21. Plans for 2017 • Early 2017 - Organisation of a limited event with participation from EU Member States and other key entities; • Early-mid 2017 - Identification of preliminary user requirements and needs in the Space and Security domain; • Mid-late 2017 – Assessment of technical solutions in the framework of relevant H2020 projects; and • Late 2017 - Organisation of an open event with the participation of key stakeholders in the Space and Security domain.
