Bright key facts / Demonstrated
A year of satellite observation, made lighter to carry.
TESSERA provides 10-meter, pixel-wise annual embeddings learned from Copernicus Sentinel-1 and Sentinel-2. ESA says the model first launched in 2025; its repository and a peer-reviewed CVPR 2026 paper now document the work.
- AI’s role
- The model compresses a year of radar and optical observations into reusable per-pixel representations.
- Documented result
- ESA announced the peer-reviewed CVPR work on 4 June 2026; the paper reports 10-meter annual embeddings, and the linked repository provides implementation material. The available sources do not establish that every artifact was first released on that date.
- Important limitation
- An embedding discards information and is not a universal map.
