Maritime domain
• Wide and complex area• International regulation• Several moving objects• Changing context
Constant threatsto be monitored
Economy 90% of world’s trade is carried by sea
Security Accidents, pollution, protection of passengers
Safety Piracy, drug traffic, terrorism, illegal immigration
Context of research Raised problems Proposition Visual exploration Conclusion

Maritime Surveillance Systems
Functionalities:• Monitor current traffic• Detect anomalies• Defense, border control• General law enforcement• Protect marine environment
Limits:• Amount of data• Moving objects• Cognitive load• Complex / unknown behaviors Surveillance system at CROSS-Med La Garde

Risk management process
Based on Wybo 2012
• Analysis of events• Prediction of future• Decision-making
• Update rules• Update models• Feed anticipation
phase
• Monitor & Control• Recognition of
threats
• Risks identification• Risks modeling

Surveillance systems in use
Problem:No analysis tools!
Need to support analysis of risk behaviors for Maritime Domain Awareness
For visualization-based support:• Study the tasks and adequate Gviz solutions• Guide in the use of geovisual analytics

Goals & tasks in geovisual exploration
Characteristics of interest:• Scale / Size of the area• Amount of objects• Time of data• Time of task• Exploration question
Linked to the “cartographic interaction primitives” (Roth 2013)• Objectives (use of maps)• Operators (information
manipulation)• Operands (visualized data)

Conclusion
Major points:• Formal description of tasks in geo - exploration for maritime domain
awareness• Translation of risks into visualizable information• Parallel work: formalization of geovisual analytics environments : data,
interactions, dimensions Knowledge-based system for guiding in the use of Gviz
Perspectives :• Develop rules for the KBS• Evaluation of efficiency / utility / ease of use (Davis 1991)• Tests of various controls & interactions
