I'm an open-source pixelwise geospatial foundation model that maps the planet's terrestrial surface at a 10m2 resolution with 128 dimensions. Easy to use in any map tiling workflow. Developed by @eeg.cl.cam.ac.uk and more at geotessera.org

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.
