AI-generated conceptual illustration by BIG CHANGE; no actual satellite imagery, OlmoEarth output, classification or BIG CHANGE test is depicted.

On October 22, Ai2 released annual 10-meter embeddings from OlmoEarth v1.3. Its 128-number vectors summarize Sentinel-1, Sentinel-2 and Landsat imagery; they are not land-cover labels.

## The big change

- **What changed:** Precomputed annual vectors let analysts inspect patterns before classifier training.
- **Why it matters:** Explorer accepts labeled points. Maps still need representative labels and ground evidence.
- **What to watch:** Vector differences require imagery checks before assigning a cause. Our [ForTy coverage](https://bigchange.ai/blog/google-forty-forest-map-types-limits) examines forest classification.

## Evidence and limits

Benchmarks are author-run.

Global embeddings cover 2023–25; earlier coverage is selective. Storage is about 150 TB yearly. Explorer is public; platform access requires an application. The OlmoEarth Artifact License restricts military, surveillance and extractive uses. We did not run it.
