Leveraging Foundation Models for Earth Observation Applications

In recent years, we’ve witnessed the rise of foundation models 1 for text (e.g. chatGPT, Llama) and images (e.g. Dalle, Stable Diffusion 2), even video (e.g. Stable Video Diffusion).

Foundation models are also being developed for other fields (e.g. Medical science 3), and particularly for Earth Observation4 5 and Climate Science6. The goal of this thesis is to investigate the maturity of these models and evaluating them in real-world downstream applications, like burned area mapping7, flood detection8 9, wildfire forecasting10 11, volcanic unrest detection12 13 or similar applications with impact for social good. Beyond evaluation, this thesis is about devising ways to fine-tune these large models to work better for downstream tasks.
