How Overwatch works
Real-time wildfire detection, from space and from the ground.
We combine data from NOAA, NASA, EUMETSAT and INPE satellites across the Americas and Europe, pulled the moment it's published.
Our own detection models pick out new fires early and filter out false alarms such as industrial heat, then merge every satellite's view into one fire.
The Lazarus Sentinel network of high-resolution wildfire detection cameras gives us ground truth to train and check the models.
Follow fires on the live map, or draw any area, like your property or town, and get a free email when a new fire starts inside it.

Clouds and thick smoke hide fires, and positions are accurate to about 1 to 2 km. Overwatch is an early-warning aid, not an emergency service: if you see a fire, call 193 in Brazil or 911 in the US.
