China: Satellite Monitoring & Event Situation
Track recent event signals and monitor China 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 China 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, 41 event signals were recorded in and around China, most in the natural disaster category.

Most active areas
Event data powered by the GDELT Project. Figures cover the mapped region around China and update hourly. For situational awareness only — not for tracking or targeting individuals.
Why Analysts Watch China From Space
China is a constant subject of open-source satellite analysis: port throughput at Shanghai and Ningbo as a proxy for trade, naval movements opposite Taiwan, seasonal Yangtze flooding, and construction activity at a scale visible from orbit. Nighttime lights add an economic-activity signal that ground reporting cannot.
Typical monitoring angles
- Ship density in the Taiwan Strait and at major container ports with SAR detection
- Yangtze and Pearl River flood extent during the summer monsoon with Sentinel-1
- Industrial-zone and infrastructure build-out tracked in Sentinel-2 time series
Monitor China From Space
Off-Nadir Delta lets you watch China 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 China, ranked by severity, that you can connect to satellite imagery in one tip-and-cue workflow.
