TerrAlert — AI satellite change detection
Monitor any location on Earth with AI-powered satellite change detection. Draw an Area of Interest and TerrAlert watches it with Sentinel-2 imagery, shows public signals recorded nearby (NASA FIRMS, GLAD, RADD) as context, and alerts you by email or webhook when a new clear image shows a change.
What it detects
Deforestation and forest canopy loss
Construction and land development
Flooding and water-body expansion
Fire and burn scars
Vegetation loss and urban expansion
Why teams choose TerrAlert
Optional alert policy that waits for an independent source that can see that kind of change
Flat monthly pricing — no per-scene or per-image fees
Developer-friendly REST API (Pro and Enterprise)
Email and HMAC-signed webhook alerts
