Data only becomes truly useful when it is presented in a way that users can understand quickly. The study therefore includes a visualisation environment that projects cleaned and smoothed vessel tracks onto a geographic background, using standard latitude–longitude coordinates. Route segments are coloured according to speed on a thermochromatic scale, making it easier to spot accelerations, slowdowns and other unusual behaviours at a glance.

The interface highlights the latest estimated position with associated information such as speed in knots, heading and timestamp. Users can upload data, trigger automatic analysis and immediately see the resulting trajectory and key parameters. The system is designed to support not only situational awareness but also “metacognitive interaction”: helping users understand why certain segments or points were flagged as anomalies.

For UnderSec, these visual and interpretable outputs make it easier for different stakeholders—maritime authorities, coast guards, infrastructure operators and researchers—to share a common picture of traffic around critical and underwater infrastructures. This shared view can support coordinated responses and long-term risk assessment.
