New version of the MAESTRO paper about self-supervised Learning for Earth Observation Data 🛰️✈️🗺️
arxiv.org/abs/2508.10894
We provide an intense benchmark of different ways to deal with multitemporal, multispectral, and multimodal data (fusion strategies / normalization schemes) for MAE based model.
