A new research paper published on arXiv investigates shortcut learning in geospatial foundation models used for disaster damage assessment. The study found that models trained on familiar disasters often rely on event or scene characteristics rather than transferable evidence, leading to a significant drop in accuracy when applied to new disaster types. Researchers tested embeddings from models like TerraMind and DINOv3 on datasets such as xView2 and BRIGHT, revealing that pre-event images and even the annotated number of buildings were highly predictive. The paper suggests that feature transformations, particularly supervised contrastive learning and principal component analysis, can improve model generalization to unseen disasters, highlighting the need for robust evaluation methods.
