About this paper
Tommaso Monopoli, Fabio Montello, Claudio Rossi
A novel bi-temporal-bi-modal deep learning architecture, BBUnet, enables automatic mapping of newly occurred landslides from Sentinel-2 imagery by fusing it with Digital Elevation Model (DEM) data. The model achieves the highest F1 score of 0.348 on a new globally diverse, open-access landslide geodatabase, demonstrating the benefits of integrating topographical context for geo-hazard detection.
Key insights
- Building a globally diverse, open-access geodatabase is essential for developing deep learning models with improved generalizability across different geographical contexts.
- Utilizing a bi-temporal change detection framework is critical for accurately identifying newly occurred landslides, providing timely and actionable intelligence for emergency response.
- Integrating auxiliary topographical information from Digital Elevation Models (DEM) significantly enhances the accuracy and robustness of deep learning models for landslide delineation.
- Freely available Sentinel-2 imagery, when combined with advanced deep learning, can provide effective and cost-efficient solutions for large-scale, automated landslide monitoring.
