Ai2 releases open satellite embeddings for the whole planet with OlmoEarth v1.3
Ai2’s OlmoEarth v1.3 provides global satellite embeddings at 10-meter resolution and a browser-based map explorer alongside open weights, data and code.
AT A GLANCE
Key points
- The model produces a 128-dimensional satellite embedding for every 10-meter pixel.
- The 128-dimensional version led 20 of 27 evaluations.
- The Explorer supports change analysis, similar-region search and GeoTIFF export.
- Weights, pretraining data and code are openly available.
What is changing?
Ai2 released OlmoEarth v1.3 and precomputed global satellite embeddings on October 22. The model reads Sentinel‑1 radar, Sentinel‑2 and Landsat time series to produce a 128-dimensional vector for every 10-meter pixel on Earth. Its first 64 dimensions can also be used as a smaller embedding.
Ai2 says the 128-dimensional version scored highest on 20 of 27 evaluations across six continents, while the 64-dimensional version led on 18. The comparisons included AlphaEarth Foundations and Tessera v2. The weights, pretraining data and code are openly available.
The new OlmoEarth Embeddings Explorer can visualize landscape change across years, find similar regions, train a small classifier from a few labeled points and export the result as GeoTIFF. It requires neither an account nor a GPU.
The archive contains roughly 150 TB of 10-meter embeddings per year. Coverage is global for 2023–2025 and limited to selected countries for 2017–2022. The benchmark results are provider-reported.
