The BigDataEurope project is working to integrate big data, software, and communities to address societal challenges in Europe. The EU SatCen is building a Secure Societies community, eliciting big data user requirements, and implementing a space and security pilot. Key activities include holding workshops on big data in secure societies, webinars, presentations at events, and community building dialogues with stakeholders. The most recent workshop had 40 participants from the EC, Frontex, ESA, and other entities to present the outcomes of the project and define next steps.
