Expansion of Global and Dense Open Embeddings Dataset of Earth 🌍 We updated our previous embeddings release with three models MMEarth and DeCUR-S2, DeCUR-S1 of the Major TOM embeddings dataset, developed in collaboration with CloudFerro S.A. asterisk labs and Φ-lab, European Space Agency - ESA. Together with @mikonvergence , Jędrzej S. Bojanowski, we extend the open-access collection of open dataset of Copernicus embeddings built at global scale, providing dense coverage across the entire acquisition area of Sentinel-1 and Sentinel-2 sensors. Total embedding resources after the update: - 51 TB of AI-embeddings generated from processed Sentinel data, - over 40 billion embedding vectors, - processing of 147 TB of raw satellite data, - analysis covering more than 15 million Sentinel-1 and Sentinel-2 scenes and more than 16 trillion pixels. This project delivers open and free vectorized expansions of Major TOM datasets available on CREODIAS and Hugging Face, setting a new standard for embedding releases and enabling lightweight, scalable ingestion of Earth Observation (EO) data for countless applications.
