Contour Based Visualization of Vessel Movement Predictions Roeland Scheepens Huub van de Wetering Jarke J. van Wijk
Project PhD Project of Roeland Scheepens (2011-2015) – Visualization of heterogeneous and uncertain data in the maritime domain. – Part of Metis project: http://www.esi.nl/metis/ – Supervisors: Jarke J. van Wijk (TU/e) Huub van de Wetering (TU/e)
Context Maritime Safety and Security Domain Law Enforcement Monitoring vessel traffic for suspicious behavior. Inspired by discussions at: – MOVE meeting hosted at Marin – MOVE Summer School and YRF 2011 – Dagstuhl Seminar 12512: Representation, Analysis and Visualization of Moving Objects
Problem Intent of observed vessels not always clear When and where to use scarce resources or expensives responses, e.g.: Intercept, send Unmanned Aerial Vehicle (UAV)? Observer Suspicious vessel ? What is going to happen? Action Observation What to do? Intercept Send UAV Nothing...
Prediction Visualization How to visualize such that an operator can see where a vessel is likely to be at what time?
Prediction Visualization Contour Time Period
Prediction Visualization A colored inner lining is added to identify the vessel. Haloes are used to separate contour lines.
Prediction Visualization Predictions further in the future fade to white due to their increased uncertainty.
Prediction Visualization When and where can the suspected pirate vessel attack the tanker? ? Where/when can the pirate attack the tanker?
Prediction Visualization When and where can the suspected pirate vessel attack the tanker?
Future Work Visualization of uncertain vessel information Visualization of reasoning on vessel intent Common ground: – Uncertainty – Moving Vessels
