Researchers have evaluated three Geospatial Foundation Models (GFMs) – Terramind, DINOv3, and Prithvi-v2 – for wildfire mapping using Sentinel-2 satellite data. The study found that Low-Rank Adaptation (LoRA) was the most efficient method for adapting these models, requiring updates to less than 1% of parameters while achieving strong cross-domain generalization. Prithvi-v2, when adapted with LoRA, demonstrated the highest accuracy and the greatest improvement over full fine-tuning, suggesting a scalable solution for large-scale burned-area mapping. AI
