United States: Satellite Monitoring & Event Situation
Track recent event signals and monitor United States from space — geolocated events, the most active areas, and satellite imagery in one place. Free to browse on the Delta Watchfloor.
Quick answer — what Off-Nadir Delta is
You can monitor United States from space on Off-Nadir Delta — viewing Sentinel-1 SAR and Sentinel-2 optical imagery, tracking any area over time with anomaly detection, and overlaying geolocated event signals (from global news media) and active fires. In the past 7 days, 165 event signals were recorded in and around United States, most in the natural disaster category.

Event data powered by the GDELT Project. Figures cover the mapped region around United States and update hourly. For situational awareness only — not for tracking or targeting individuals.
Why Analysts Watch United States From Space
In the United States, satellite monitoring is dominated by natural-hazard response: hurricane landfalls on the Gulf and Atlantic coasts, wildfire seasons in California and the West, and Mississippi-basin flooding. Add the world’s busiest container ports and you have a country where event signals and imagery intersect daily.
Typical monitoring angles
- Wildfire perimeters and hotspots in the western states via NASA FIRMS and burn-scar analysis
- Hurricane flood extent mapped with Sentinel-1 SAR when optical sensors are blocked by storm cloud
- Container-ship queues at Los Angeles/Long Beach and Gulf Coast ports
Monitor United States From Space
Off-Nadir Delta lets you watch United States without any GIS software. View Sentinel-1 SAR (all-weather, day or night) and Sentinel-2 optical imagery, draw any area to build a time series with anomaly detection, and overlay active fires.
The Delta Watchfloor adds the event layer: geolocated signals in and around United States, ranked by severity, that you can connect to satellite imagery in one tip-and-cue workflow.
