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.

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
