Off-Nadir Delta

Yemen: Satellite Monitoring & Event Situation

Track recent event signals and monitor Yemen 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 Yemen 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, 144 event signals were recorded in and around Yemen, most in the armed conflict category.

Event data powered by the GDELT Project. Figures cover the mapped region around Yemen and update hourly. For situational awareness only — not for tracking or targeting individuals.

Why Analysts Watch Yemen From Space

Yemen sits on the Bab el-Mandeb strait, one of the world’s critical shipping chokepoints, and attacks on Red Sea shipping have made the surrounding waters a permanent satellite watch area. Onshore, port operations at Hodeidah and humanitarian conditions dominate.

Typical monitoring angles

  • Ship routing and density through the Bab el-Mandeb and southern Red Sea
  • Port operations at Hodeidah and Aden with SAR ship detection
  • Flash-flood impact on wadi settlements after seasonal storms

Monitor Yemen From Space

Off-Nadir Delta lets you watch Yemen 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 Yemen, ranked by severity, that you can connect to satellite imagery in one tip-and-cue workflow.

Frequently Asked Questions

How can I monitor Yemen with satellite imagery?▼
On Off-Nadir Delta you can view Sentinel-1 SAR and Sentinel-2 optical imagery over Yemen, draw any area to monitor it over time with anomaly detection, and overlay NASA FIRMS active fires. The Delta Watchfloor also shows geolocated event signals in and around Yemen, so you can connect what is happening on the ground to what satellites see.
Where does the Yemen event data come from?▼
Geolocated event signals are drawn from global news media and official hazard feeds — open monitoring of world events — AI-enriched and continuously refreshed. The data is for situational awareness and is not intended for tracking or targeting individuals.
Is monitoring Yemen free?▼
Browsing the latest event signals on the Watchfloor is free and needs no account. Deeper capabilities — longer history and AI remote-sensing deep-dives — are available on paid plans or metered by tokens. See the pricing page for details.
