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

Main Objective of the SC7 Pilot
Automatically detect
land cover evolution,
caused by physical or
human activities, and
alert users
accordingly.

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

Event Detection Workflow
Pilot Data Sources
◎ Sentinel-1o 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
◎ Twittero Free Twitter Public Streams API and specific user accounts
o Plain text along with metadata in JSON format

Pilot Status
◎ Change Detection Workflowo System able to search, download and (pre-)process images in parallel (Spark)
◎ Event Detection Workflowo System able to continuously monitor social media and news agencies
o Events clustered and mapped to geolocations
◎ Activation Workflowo 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

Future Developments
◎ Overall SC7 Piloto Add cybersecurity mechanisms (e.g. authentication / authorization)
o Add more data sources for both workflows (e.g., HR satellite images)
◎ Change Detection Workflowo Improve classification accuracy
◎ Event Detection Workflowo Dockerize Spark version
◎ Activation Workflowo New GUI functionalities according to user feedback
