New foundation model fuses hyperspectral imagery with other Earth observation data

By PulseAugur Editorial · [2 sources] ·

Researchers have developed SpectralEarth-FM, a new foundation model designed to process and fuse hyperspectral imagery with other Earth observation data like multispectral, radar, and temperature readings. This model utilizes a hierarchical transformer architecture that can handle varying spectral dimensions and integrates a cross-sensor fusion module. To train SpectralEarth-FM, a large dataset called SpectralEarth-MM was curated, containing over 40TB of co-located data from multiple satellite sensors, enabling state-of-the-art results on downstream tasks.

    SpectralEarth-FM: Bringing Hyperspectral Imagery into Multimodal Earth Observation Pretraining

    Earth observation (EO) foundation models (FMs) are increasingly trained on multisensor data, spanning multispectral imagery (MSI), synthetic aperture radar (SAR), and derived geospatial layers, but hyperspectral imagery (HSI) remains underrepresented. Conversely, existing hypersp…
