  • 1. CRC Centre de recherche sur les Risques et les Crises Geovisual Analytics for Maritime Surveillance Proposing the Most Suitable Methods for the Users Gabriel Vatin, Aldo Napoli MINES ParisTech Center of research on Risks and Crisis International Cartographic Conference 2013 – Dresden, Germany
  • 2. ICC’13 – Dresden, Germany – August 2013 Maritime domain • Wide and complex area • International regulation • Several moving objects • Changing context Constant threats to 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 2
  • 3. ICC’13 – Dresden, Germany – August 2013 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 3
  • 4. ICC’13 – Dresden, Germany – August 2013 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 Anticipation Vigilance Handling with unexpected Lessons from the past Context of research Raised problems Proposition Visual exploration Conclusion 4
  • 5. ICC’13 – Dresden, Germany – August 2013 Context of research Raised problems Proposition Visual exploration Conclusion 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 5
  • 6. ICC’13 – Dresden, Germany – August 2013 Context of research Raised problems Proposition Visual exploration Conclusion Related work Riveiro 2011 Andrienko & Andrienko 2013 Mallé-Noyon 2008 Willems 2011 6
  • 7. ICC’13 – Dresden, Germany – August 2013 Context of research Raised problems Proposition Visual exploration Conclusion Use of knowledge Query / Selection interface User Goal Gviz solutions proposal Knowledge-based system RulesOntology Working environment Context of Use 7
  • 8. ICC’13 – Dresden, Germany – August 2013 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) Context of research Raised problems Proposition Visual exploration Conclusion 8
  • 9. ICC’13 – Dresden, Germany – August 2013 Context of research Raised problems Proposition Visual exploration Conclusion Exploration & analysis of traffic information A few tasks for using geovisual analytics for maritime domain awareness Spatio- temporal analysis 2 Risk identification 4 General identification 1 Context analysis 3 9
  • 10. ICC’13 – Dresden, Germany – August 2013 Attributes of interest Context of research Raised problems Proposition Visual exploration Conclusion Stop at Sea Space: •Ship location •Stops location •Sensitive area? Time / Dynamic: •Stop duration •Speed Ship infos: •Type •Country 10 Measure Compare …. Locate Characterize … Identify …
  • 11. ICC’13 – Dresden, Germany – August 2013 Trajectory display Context of research Raised problems Proposition Visual exploration Conclusion No clue about the dynamic of the trajectory 11
  • 12. ICC’13 – Dresden, Germany – August 2013 Speed & stops display Context of research Raised problems Proposition Visual exploration Conclusion Long stop Short stops 12
  • 13. ICC’13 – Dresden, Germany – August 2013 Speed & stops display Context of research Raised problems Proposition Visual exploration Conclusion 13 Fishing behavior: user own knowledge
  • 14. ICC’13 – Dresden, Germany – August 2013 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 Context of research Raised problems Proposition Visual exploration Conclusion 14
