TLDR
LandSAR is an immersive analytics system that visceralizes landslide data using integrated simulations and 3D-printed terrain for enhanced situational awareness.
Key contributions
- LandSAR enhances landslide analysis by visceralizing data through integrated simulations and visualizations.
- Supports real-time simulations of landslide dynamics, prevention, and climate impacts for 'what-if' analyses.
- Uses 3D-printed terrain models as tangible interfaces for haptic feedback and gesture-based exploration.
- Expert interviews confirm LandSAR effectively improves situational awareness and user engagement.
Why it matters
Understanding complex landslide dynamics is crucial for public safety but challenging with abstract data. LandSAR bridges this gap by making simulation data tangible and interactive. This enhances analysts' situational awareness, leading to better decision-making for prevention and response.
Original Abstract
Landslides pose a significant threat to public safety, but their dynamic processes are difficult to analyze from post-event observation alone. Computational simulation is therefore essential, but it generates vast, abstract datasets that create a cognitive gap between the analyst and the real-world, physical terrain. While Immersive Analytics (IA) begins to bridge this gap by visualizing data in 3D, we explore how these systems evolve beyond abstract data and integrate data visceralization to enhance Situational Awareness (SA). We present LandSAR, an immersive analytics system that enhances SA for landslide analysis by visceralizing landslide data through integrated simulations and visualizations. LandSAR supports real-time simulations of landslide dynamics, prevention strategies, and climate impacts, enabling multi-perspective what-if analyses. The system uses 3D-printed terrain models as tangible interfaces to facilitate haptic feedback and enable gesture-based exploration, allowing for intuitive geographical perception. Expert interviews and workshops demonstrate that LandSAR effectively improves SA and engagement.
