SpectralEarth-FM is a multisensor hierarchical transformer pretrained on a 40TB co-located HSI-MSI-SAR dataset using a JEPA-style objective and reports state-of-the-art results on hyperspectral and standard EO benchmarks.
HSI acquisitions are used as anchors, filtered, patchified, grouped by location, rebalanced, and paired with co-located MSI, SAR, and LST observations
