SpectralGPT: The first remote sensing foundation model customized for spectral data

<p>SpectralGPT is the first purpose-built foundation model designed explicitly for spectral RS data. It&nbsp;considers unique characteristics of spectral data, i.e., spatial-spectral coupling and spectral sequentiality, in the MAE framework with a simple yet effective 3D GPT network.</p> <p>We will gradually release the trained models (SpectralGPT, SpectralGPT+), the new&nbsp;benchmark dataset (SegMunich) for the downstream task of&nbsp;semantic segmentation, original code, and implementation instructions.</p>
