Explore the marine terminal connectivity of publicly posted carrier master service schedules.

The node-link diagram pane represents a directed network graph with marine terminals (nodes) as circles and carrier service connections (edges) as lines with arrows. By default, a user may see terminals represented by a white color and all network connections, albeit in a faded out manner. Hovering over a marine terminal displays details such as the terminal’s identifying code, facility name, address, and the port it belongs to. The hover interaction also brings attention to the terminal of interest by changing the terminal’s color to deep red and taking advantage of the pop-out effect. The terminal encoding returns to default when the user interaction focus changes. A selection in the carrier filters pane changes color of the associated terminal nodes to a red outline with a pink fill and brings the connections into focus using color highlighting. When in view, the connections are encoded with a blue or orange color rep- resenting a respective East or West trade lane. This is important to highlight because a carrier may not visit a facility in both directions. The force-directed node-link diagram is advantageous for showing network data because it removes geographic distance and allows the user to focus clearly on specific nodes and edges connections.

Explore the shortest navigable maritime paths between marine terminals of publicly posted carrier master service schedules.
For a selected vessel, view the actual trajectory (historical path) over a set time period.

*Note: the shortest paths paths may not reflect the ideal route.

The geographic map pane displays marine terminals, an optimal maritime route (shortest distance) between terminals, and the trajectory (historical path) for vessels over a set time period. By default, a user may see terminals represented by a white circle. Hovering over a marine terminal displays details such as the terminal’s identifying code, facility name, address, and the port it belongs to. The hover interaction also brings attention to the terminal of interest by changing the terminal’s color to deep red and taking advantage of the pop-out effect. The terminal encoding returns to default when the user interaction focus changes. A selection in the carrier filters pane changes color of the associated terminal nodes to a red outline with a pink fill and brings optimal maritime routes of the carrier network into focus using color highlighting. The optimal maritime route is calculated using the SeaRoute model from the European Union’s statistical office. These elements are not visible by default and ap pear red for a carrier selection. Although these connections may not be accurate for navigation, they show the shortest distance between terminal pairings and provide a base comparison against actual vessel movements (trajectories). A vessel table selection links to this map view and displays the corresponding vessel(s) trajectory for the dataset time period. The trajectory for each vessel is encoded with a different color allowing users can visually compare the actual paths for vessels assigned to the same service as well as the optimal route.
