The 6th International Workshop on Information Fusion and Geographic Information Systems (IF&GIS 2013)
St Petersburg, Russia, May, 2013
• Worldwide, there are still many thousands of maritime accidents each year,
• 445 acts of piracy recorded (+8.5% in one year) and 1181 marine taken hostages in 2010 (BMI, 2010),
• 54 700 tonnes of oil and hazardous substances accidentally discharged in 2009 against 7500
tonnes in 2008 (Cedre, 2009)
Context
2
• 90% of international trade,
• 80% of energy transport,
• 1.19 billion Deadweight tons (dwt) in 2009, 6.7% more compared to 2008 (CNUCED, 2009).
 Maritime activity: risks generator context
A risk is the eventuality of event that may cause harmful effects (Boisson, 1998)
• Risks related to safety: collision, grounding, etc.
• Risks related to security: piracy, illicit goods, etc.
 The need to use means of monitoring, control and repression
• Organisms responsible for safety and security,
• Regulations (ENC, legislative packages Erika I, II, III, etc.),
• Systems of navigational aid (NavTrack, Marine GIS, ex-Trem, etc..),
• Maritime tracking systems (Spationav, SIVE, SYTAR, etc..)
 The importance of maritime activity
 Risk always important despite means implemented

Maritime tracking systems

Definition: they allow the retrieval and fusion of information on vessels (position,
heading, speed, etc.) for monitoring traffic on a display device (screen, touch table,
etc.) .

Control interface Maritime surveillance
operator
Data acquisition
infrastructure
 Improvement of these systems:
 Increase detection capabilities: new sensors (FMCW radar for small boats, waves of long
range surface)
 Integrate new databases to analyze weather, oceanographic context, etc.
 Integrate the decision aid tools to post-hoc analysis and identify risk behaviors
Risk behavior: movement (s) + conditions describing a risk
• Movement: spatio-temporal (position change)
• Conditions: vessel characteristics, environment, etc.
Introduction > Proposition > Application > Conclusion

4
 The maritime surveillance systems display operational data difficult to exploit for
decision-making
 These data are not saved to a post-hoc analysis
 Decision-making functions of collecting multi-source data to presentation to
users are not supported
 The problem of maritime surveillance can be seen as a problem of
spatiotemporal decision aid
 Operators should monitor ships as mobile objects moving in a spatiotemporal
open space and make decisions on risky behaviors

Approaches to decision support
5
 Many ways to improve decision support in the maritime domain
 Approaches based on advanced spatial analysis (Claramunt et al., 2007)
 Knowledge representation (Vandecasteele et al.,2012)
 Automatic risk identification (Idiri et al., 2012)
 Knowledge extraction about risk behavior based on historical data

Spatial data
mining
Spatial OnLine
Analytical
Processing
 Formalize the use of geo-decision-making tools in the form of a chain
(using the analogy of the decision-making chain) with the aim of support all
Geo-decision-making functions
 Spatial data mining and Spatial OnLine Analytical Processing allows the extraction of:
 Patterns (spatial and temporal unusual frequent, periodic, groups, etc.)
 Relationships (association rules, sequential, etc.).
Introduction > Proposition > Application > Conclusion
The post-hoc analysis of maritime risks
7
The data repository (or SDW) that records the evolution of maritime activity serves
as a tool for automatic (SDM) data mining and visual (SOLAP) data mining that leads
to knowledge discovery on risk behaviors.
Definition:
Spatial Data Mining is the non-trivial extraction of implicit and potentially useful
knowledge from data supplied by the spatial database (Krzysztof et al., 1995)
The Spatial OLAP has been defined by Bédard as, “a visual platform specifically
designed to support a rapid and efficient spatiotemporal analysis through a
multidimensional approach that includes mapping, graphical and tabular levels of
aggregation” (Bédard , 1997)

 MAIB data:
 Historical accidents/incidents between 1991 and 2009,
 14,900 accidents and incidents,
 16,230 ships.
 MERRA data:
 Provides meteorological data from the period 1991-2009,
 Regular download (1 time/day) to supply the facts.
 AIS data:
 Historical data since ~ 4 months,
 Continuous flow of ship movements.

 Results
 Formalize a paradigm that we call geo-decision-making chain
 Apply the geo-decision-making chain to the domain of maritime surveillance
that supports all decision-making functions, from data collection to its
presentation to decision-makers
 Automatic and visual extraction of risky behaviors from data
Introduction > Proposition > Application > Conclusion
 Future works
 Apply other data mining algorithms (periodic patterns, convoy, etc.) to
extract risky behaviors
 Design and develop a software workshop integrating automatic methods
for data mining and visual aid for analysis and subsequent identification of
risk behaviors

Conclusion 11  Results  Formalize a paradigm that we call geo-decision-making chain  Apply the geo-decision-making chain to the domain of maritime surveillance that supports all decision-making functions, from data collection to its presentation to decision-makers  Automatic and visual extraction of risky behaviors from data Introduction > Proposition > Application > Conclusion  Future works  Apply other data mining algorithms (periodic patterns, convoy, etc.) to extract risky behaviors  Design and develop a software workshop integrating automatic methods for data mining and visual aid for analysis and subsequent identification of risk behaviors

  1. To achieve this integration of data mining into maritime surveillance systems, we formalized the use of geo-decision-making tools in the form of a chain (using the analogy of the decision-making chain).
