LTM: Large-scale Terrain Model for Wildfire-prone Landscapes

arXiv:2607.08711v1 Announce Type: cross Abstract: Accurate 3D terrain maps are essential for emergency response when assessing wildfire hazards. However, wildfire-prone regions often span vast areas where conventional reconstruction methods underperform. Airborne LiDAR systems provide high-resolution terrain data, but they are expensive and infrequently updated. Image-based methods offer a lower-cost alternative, but struggle due to sparse visual features and limited image overlap. We propose a multi-modal reconstruction framework leveraging outdated Digital Elevation Models (DEMs) as geometri

Why this matters
Why now

Advances in multi-modal AI and improved data aggregation techniques are enabling more sophisticated environmental monitoring solutions, reflecting a push for better disaster preparedness.

Why it’s important

Accurate terrain mapping for wildfire-prone areas is critical for effective emergency response, resource allocation, and risk mitigation, directly impacting lives and infrastructure.

What changes

The ability to generate large-scale, accurate 3D terrain models using a combination of LiDAR and image-based data improves monitoring capabilities in challenging and vast geographical regions.
