  10. 10. The Challenges: data to knowledge 10 Data Observation Theory Knowledge • Managing exponential increase in rates and volumes. • Empowering the end user for multi-purpose processing, analytics, data mining and exploration. • Data Fusion with big multi-wavelength data and big simulations • Collaboration, sharing and joint execution of data-intensive projects by globally distributed teams of researchers
  11. 11. SKA Regional “Science” and Data Centres What is the “roadmap”-how do we get there from here? • Leverage South African Investment in MeerKAT to SA expertise and leadership • Engage university researchers as stakeholder and drivers of innovation • Training of cohort of required data scientists • “Precursor” SKA Regional Science Centres?
