Multitemporal foundation models for EO
Multitemporal Foundation Models for EO
Foundation Models (FMs) represent the latest leap forward in Artificial Intelligence (AI), following the era of Deep Learning. Trained on vast amounts of unlabeled data through self-supervised learning (SSL), these models capture rich patterns that can be applied to a wide array of downstream tasks—even with limited or no additional training data. This paradigm holds particular promise for Earth Observation (EO) and Earth Sciences by enabling breakthroughs in analytical, predictive, and even prescriptive capabilities.
In EO and Earth Sciences, FMs can significantly enhance applications such as weather prediction and geospatial semantic data mining. By analyzing large-scale climate and atmospheric datasets, they deliver more accurate forecasts across different time horizons and reveal complex patterns in environmental systems. Their latent space representations and embeddings also enable powerful insights while reducing the need for extensive labeled data—a critical advantage in remote sensing, where labeling is often expensive and time-consuming.
Despite these benefits, integrating FMs into EO workflows poses distinct challenges. EO data often spans multiple modalities, resolutions, and spectral bands, requiring specialized adaptation and careful model updating—especially for “digital twin” scenarios where AI must remain synchronized with real-world changes. Moreover, FMs demand significant computational resources and optimized training strategies, particularly when handling enormous, continuously growing geospatial datasets. Evaluating and benchmarking FMs for these specialized applications further complicates their deployment, as existing benchmarks may be limited in scope.
