Why rebuild an AI pipeline just to find a forest change? Ai2's October twenty-second OlmoEarth release lets you start with satellite features already computed, then explore them in a browser.
Think of an embedding as a compact description of a patch of ground. The model combines a year of radar and other satellite observations. You can reuse that description to find similar places or train a small map classifier.
The new explorer lets you mark examples, compare years and export a map without an account. This is a first pass for asking where land changed, not a live camera or proof of what caused the change.
Coverage has a catch. The release has global data for twenty twenty-three through twenty twenty-five. Earlier years cover selected countries. The dataset excludes Antarctica, and missing data must not be mistaken for unchanged land.
We have not independently tested its accuracy. Its license restricts military, surveillance and resource-extraction uses. Check a result against the underlying imagery and local knowledge. Watch whether a useful map survives that check before acting on it.
