I've been using TESSERA embeddings to look at Lake Baringo in Kenya and wrote up what I found: www.fathir.live/blog/tessera... I'd really like feedback from the team, especially if I got anything wrong or there's a better way to do it. Thanks for building TESSERA!

Every 10 Metres of Earth in 128 Numbers: A Practical Introduction to TESSERA

What Cambridge's satellite embeddings are, what you can do with them, and one real use case: measuring the rise of Kenya's Lake Baringo from 2017 to 2025 without training a model.

Countries like Senegal could soon use #AI to help plan for food shortages. Former @cam.ac.uk PhD student Madeline Lisaius mapped smallholder crops with Tessera, beating other methods with far less computing power and labelled data. Read more: www.cam.ac.uk/research/new... #FoodSecurity 📷 @wfp.org

Can university teams train large-scale foundation models? Yes! At @geotessera.org, we've been training state-of-the-art FMs from scratch at Cambridge. This involved vast data shuffling, stuffing every SSD we can find, overloading network links, jury-rigging GPU farms, and using national clusters.

It's been an eventful year since we launched Tessera, our geospatial foundation model. Here's a few highlight moments from the past year... Learn more about using Tessera embeddings at geotessera.org or dive right in and join our user community here eeg.zulipchat.com

Thank you for following Tessera. Some highlights since we launched our geospatial foundation model.

We presented our first peer-reviewed paper at CVPR 2026, and later released Tessera v1.1 with greater stability and fewer artefacts.

We used Tessera embeddings to map farms, forests and elusive hedgehog habitats, and we welcomed fresh new faces!

Tessera v2 embeddings are on the way. Learn more at

We're a step closer to Tessera v2! Our preprint paper is online and v2 models are available to download. We're working on generating v2 embeddings and plan to make these available in the coming months. Checkout the Tessera v2 preprint paper: geotessera.org/papers

Small farms grow much of the world's food, but from space are nearly invisible. Now AI tool Tessera, trained on years of satellite imagery, shows it can map crops on small farms better & cheaper than standard methods, which could greatly aid food security planning. www.cst.cam.ac.uk/news/how-ai-...
