SC7 Workshop 2: Demo of the BigDataEurope pilot for Secure Societies

  1. 1. DEMO OF THE BDE PILOT FOR SECURE SOCIETIES 2nd Workshop on “Big Data in Secure Societies”18/10/2016 Manolis Koubarakis, University of Athens Michele Lazzarini, EU Satellite Center George Papadakis, University of Athens Emanouil Thanos, University of Athens
  2. 2. SC7 – Secure Societies SC7 societal challenge is about protecting freedom and security of Europe and its citizens. In other words:  enhance resilience against natural and man-made disasters  develop novel solutions for the protection of critical infrastructure  fight crime and terrorism  improve border security  provide enhanced cyber-security 20-oct.-16www.big-data-europe.eu
  3. 3. Main Objective of the SC7 Pilot Automatically detect land cover evolution, caused by physical or human activities, and alert users accordingly. 20-oct.-16www.big-data-europe.eu Amatrice Earthquake August 24, 2016
  4. 4. Technical Objectives Track changes in land cover/land use by integrating heterogeneous information sources:  Detect changes using satellite images  Monitor related information in social media 20-oct.-16www.big-data-europe.eu
  5. 5. High-Level Architecture 20-oct.-16www.big-data-europe.eu Remote Sensing Big Data Platform Social Sensing Change Detection Workflow Event Detection Workflow
  6. 6. Pilot Data Sources ◎ Sentinel-1 o Free and open data (radar images) o Satellites operated by ESA in the framework of the Copernicus programme funded and managed by EC o Same area acquired every 6 days with 2 satellites ◎ Twitter o Free Twitter Public Streams API and specific user accounts o Plain text along with metadata in JSON format ◎ Reuters o News articles through RSS feeds in XML format 20-oct.-16www.big-data-europe.eu
  7. 7. Pilot Architecture 20-oct.-16www.big-data-europe.eu Event Detection Change Detection
  8. 8. Pilot Status ◎ Change Detection Workflow o System able to search, download and (pre-)process images in parallel (Spark) ◎ Event Detection Workflow o System able to continuously monitor social media and news agencies o Events clustered and mapped to geolocations ◎ Activation Workflow o GIS interface (Sextant) allows users to activate the two workflows o Geographic information stored in Strabon and queried through SPARQL ◎ All components and workflows setup on BDE infrastructure 20-oct.-16www.big-data-europe.eu
  9. 9. Future Developments ◎ Overall SC7 Pilot o Add cybersecurity mechanisms (e.g. authentication / authorization) o Add more data sources for both workflows (e.g., HR satellite images) ◎ Change Detection Workflow o Improve classification accuracy ◎ Event Detection Workflow o Dockerize Spark version ◎ Activation Workflow o New GUI functionalities according to user feedback 20-oct.-16www.big-data-europe.eu
  10. 10. Demo ◎ GUI / Sextant functionalities for BigDataEurope (Real Time) ◎ Change Detection activation (Real Time) ◎ Event Detection activation (Real Time) ◎ Results Visualization (Not Real Time) 1. Pilot on UoA server 2. BackUp Video 20-oct.-16www.big-data-europe.eu
